An SBML Event object defines when the event can occur, the variables that are affected by it, how the variables are affected, and the event's relationship to other events. The effect of the event can optionally be delayed after the occurrence of the condition which invokes it.
The operation of Event is divided into two phases (even when the event is not delayed): one when the event is triggered, and the other when the event is executed. Trigger objects define the conditions for triggering an event, Delay objects define when the event is actually executed, EventAssignment objects define the effects of executing the event, and (in SBML Level 3) Priority objects influence the order of EventAssignment performance in cases of simultaneous events. Please consult the descriptions of Trigger, Delay, EventAssignment and Priority for more information.
In SBML Level 2 versions before Version 4, the semantics of Event time delays were defined such that the expressions in the event's assignments were always evaluated at the time the event was triggered. This definition made it difficult to define an event whose assignment formulas were meant to be evaluated at the time the event was executed (i.e., after the time period defined by the value of the Delay element, or after any other simultaneous event may have been executed and changed the model state). In SBML Level 2 Version 4 and in Level 3, the attribute 'useValuesFromTriggerTime' on Event was added to allow a model to indicate the time at which the event's assignments are to be calculated, whether at the moment the event is triggered (if the value of the attribute is true), or at the moment of execution (if 'useValuesFromTriggerTime'=false). If the event has a delay, the 'useValuesFromTriggerTime' is likely to make a significant difference in the values used in the assignment, but the possibility of simultaneous events mean that even zero-delay events can have different results depending on the value of this attribute.
The definition of Event in SBML Level 2 Versions 1 and 2 includes an additional attribute called 'timeUnits', which allowed the time units of the Delay to be set explicitly. Later Versions of SBML Level 2 as well as SBML Level 3 do not define this attribute. LibSBML supports this attribute for compatibility with previous versions of SBML Level 2; however, if a model in SBML Level 3 or Level 2 Versions 3–4 format sets the attribute, the consistency-checking method SBMLDocument::checkConsistency() will report an error.
The attribute 'useValuesFromTriggerTime' was introduced in SBML Level 2 Version 4. Models defined in prior Versions of SBML Level 2 cannot use this attribute, and SBMLDocument::checkConsistency() will report an error if they do.
SBML Level 3 introduces several changes to the structure and components of Events compared to SBML Level 2. These changes fall into two main categories: changes to what is optional or required, and additions of new attributes and elements.
true); The changes to the attributes of Event are described below; the changes to Trigger and Priority are described in their respective sections.
The detailed semantics of events are described in the specification documents for each SBML Level/Version. Here we include the description from the SBML Level 1 Version 1. Any transition of a Trigger object's 'math' formula from the value false to true will cause the enclosing Event object to trigger. Such a transition is not possible at the very start of a simulation (i.e., at time t = 0) unless the Trigger object's 'initialValue' attribute has a value of false; this defines the value of the trigger formula to be false immediately prior to the start of simulation, thereby giving it the potential to change in value from false to true when the formula is evaluated at t = 0. If 'initialValue'=true, then the trigger expression cannot transition from false to true at t = 0 but may do so at some time t > 0.
Consider an Event object definition E with delay d in which the Trigger object's 'math' formula makes a transition in value from false to true at times t1 and t2. The EventAssignment within the Event object will have effect at t1 + d and t2 + d irrespective of the relative times of t1 and t2. For example, events can 'overlap' so that t1 < t2 < t1 + d still causes an event assignments to occur at t1 + d and t2 + d.
It is entirely possible for two events to be executed simultaneously, and it is possible for events to trigger other events (i.e., an event assignment can cause an event to trigger). This leads to several points:
A software package should retest all event triggers after executing an event assignment in order to account for the possibility that the assignment causes another event trigger to transition from false to true. This check should be made after each individual Event object's execution, even when several events are to be executed simultaneously.
Any Event object whose Trigger 'persistent' attribute has the value false must have its trigger expression reevaluated continuously between when the event is triggered and when it is executed. If its trigger expression ever evaluates to false, it must be removed from the queue of events pending execution and treated as any other event whose trigger expression evaluates to false.
Although the precise time at which events are executed is not resolved beyond the given execution point in simulated time, it is assumed that the order in which the events occur is resolved. This order can be significant in determining the overall outcome of a given simulation. When an event X triggers another event Y and event Y has zero delay, then event Y is added to the existing set of simultaneous events that are pending execution. Events X and Y form a cascade of events at the same point in simulation time. An event such as Y may have a special priority if it contains a Priority subobject.
All events in a model are open to being in a cascade. The position of an event in the event queue does not affect whether it can be in the cascade: event Y can be triggered whether it is before or after X in the queue of events pending execution. A cascade of events can be potentially infinite (never terminate); when this occurs a simulator should indicate this has occurred—it is incorrect for a simulator to break a cascade arbitrarily and continue the simulation without at least indicating that the infinite cascade occurred.
Simultaneous events having no defined priorities are executed in an undefined order. This does not mean that the behavior of the simulation is completely undefined; merely that the order of execution of these particular events is undefined. A given simulator may use any algorithm to choose an order as long as every event is executed exactly once.
Events with defined priorities are executed in the order implied by their Priority 'math' formula values, with events having higher priorities being executed ahead of events with lower priorities, and events with identical priorities being executed in a random order with respect to one another (as determined at run-time by some random algorithm equivalent to coin-flipping). Newly-triggered events that are to be executed immediately (i.e., if they define no delays) should be inserted into the queue of events pending execution according to their priorities: events with higher priority values value must be inserted ahead of events with lower priority values and after any pending events with even higher priorities, and inserted randomly among pending events with the same priority values. Events without Priority objects must be inserted into the queue in some fashion, but the algorithm used to place it in the queue is undefined. Similarly, there is no restriction on the order of a newly-inserted event with a defined Priority with respect to any other pending Event without a defined Priority.
A model variable that is the target of one or more event assignments can change more than once when simultaneous events are processed at some time point t. The model's behavior (output) for such a variable is the value of the variable at the end of processing all the simultaneous events at time t.
In SBML Level 3 Version 2, several restrictions were lifted that have the potential to affect the semantics of an Event:
The Trigger subobject of an Event is optional. If missing, an Event is never triggered, unless an alternate triggering scheme is introduced by an SBML Level 3 package.
The 'math' subelements of an Event Trigger, Delay, Priority, and EventAssignment are all optional. If any of these elements lack a 'math' subelement, and that information is not supplied in an SBML Level 3 package, it is mathematically equivalent to the Trigger, Delay, Priority, or EventAssignment not being present at all.
The ListOfEventAssignments may be empty, which is mathematically equivalent to the Event not having a ListOfEventAssignments at all.
false, and all other values are interpreted as true. If a Boolean value is used in a numeric context, a true is interpreted as a 1, and a false is interpreted as a 0. This means (for example) that a Trigger value that changes from 0.0 to anything else is equivalent to changing from false to true. Public Member Functions | |

Disables the given SBML Level 3 package on this object.
This method disables the specified package on this object and other objects connected by child-parent links in the same SBMLDocument object.
An example of when this may be useful is during construction of model components when mixing existing and new models. Suppose your application read an SBML document containing a model that used the SBML Hierarchical Model Composition (“comp”) package, and extracted parts of that model in order to construct a new model in memory. The new, in-memory model will not accept a component drawn from an other SBMLDocument with different package namespace declarations. You could reconstruct the same namespaces in the in-memory model first, but as a shortcut, you could also disable the package namespace on the object being added. Here is a code example to help clarify this:

Returns the value of the 'id' attribute of this Event.
The identifier given by an object's 'id' attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier. The data type of 'id' is always SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows:
letter ::= 'a'..'z','A'..'Z' digit ::= '0'..'9' idChar ::= letter | digit | '_' SId ::= ( letter | '_' ) idChar*
The characters ( and ) are used for grouping, the character * 'zero or more times', and the character | indicates logical 'or'. The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.
Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined 'id' and 'name' attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have 'id' or 'name' attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: 'variable' (for the rules and event assignments), 'symbol' (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return false for objects of these classes.
With the addition of 'id' and 'name' attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original 'id' methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual 'id' attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an 'id' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write 'id' attributes for those objects.

Returns the SBML Level of the SBMLDocument object containing this object.
LibSBML uses the class SBMLDocument as a top-level container for storing SBML content and data associated with it (such as warnings and error messages). An SBML model in libSBML is contained inside an SBMLDocument object. SBMLDocument corresponds roughly to the class SBML defined in the SBML Level 3 and Level 2 specifications, but it does not have a direct correspondence in SBML Level 1. (But, it is created by libSBML no matter whether the model is Level 1, Level 2 or Level 3.)

Returns the value of the 'metaid' attribute of this SBML object.
The optional attribute named 'metaid', present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the 'metaid' attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the 'annotation' subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.

Returns the ModelHistory object, if any, attached to this object.
null if none exist.| new string libsbmlcs.Event.getName | ( | ) |
Returns the value of the 'name' attribute of this Event.
In SBML Level 3 Version 2, the 'id' and 'name' attributes were moved to SBase directly, instead of being defined individually for many (but not all) objects. LibSBML has for a long time provided functions defined on SBase itself to get, set, and unset those attributes, which would fail or otherwise return empty strings if executed on any object for which those attributes were not defined. Now that all SBase objects define those attributes, those functions now succeed for any object with the appropriate level and version.
The 'name' attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of 'name' is the type string defined in XML Schema. SBML imposes no restrictions as to the content of 'name' attributes beyond those restrictions defined by the string type in XML Schema.
The recommended practice for handling 'name' is as follows. If a software tool has the capability for displaying the content of 'name' attributes, it should display this content to the user as a component's label instead of the component's 'id'. If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the 'name' attribute is missing on a given component, then the user interface should display the value of the 'id' attribute instead. (Script language interpreters are especially likely to display 'id' instead of 'name'.)
As a consequence of the above, authors of systems that automatically generate the values of 'id' attributes should be aware some systems may display the 'id''s to the user. Authors therefore may wish to take some care to have their software create 'id' values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the 'id' attribute be an abbreviated form of the name attribute value.
An additional point worth mentioning is although there are restrictions on the uniqueness of 'id' values, there are no restrictions on the uniqueness of 'name' values in a model. This allows software applications leeway in assigning component identifiers.
Regardless of the level and version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have names). If the object in question does not posess a 'name' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the name to be set, nor will it read or write 'name' attributes for those objects.

Returns the content of the 'notes' subelement of this object as a tree of XMLNode objects.
The optional SBML element named 'notes', present on every major SBML component type (and in SBML Level 3, the 'message' subelement of Constraint), is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.
The format of 'notes' elements conform to the definition of XHTML 1.0. However, the content cannot be entirely free-form; it must satisfy certain requirements defined in the SBML specifications for specific SBML Levels. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); this method implements a verification process that lets callers check whether the content of a given XMLNode object conforms to the SBML requirements for 'notes' and 'message' structure. Developers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations of using 'notes' in SBML. The SBML Level 2 and 3 specifications have considerable detail about how 'notes' element content must be structured.
The 'notes' element content returned by this method will be in XML form, but libSBML does not provide an object model specifically for the content of notes. Callers will need to traverse the XML tree structure using the facilities available on XMLNode and related objects. For an alternative method of accessing the notes, see getNotesString().

A given model may indicate that it uses one or more SBML packages, and likewise, a software tool may be able to support one or more packages. LibSBML does not come preconfigured with all possible packages included and enabled, in part because not all package specifications have been finalized. To support the ability for software systems to enable support for the Level 3 packages they choose, libSBML features a plug-in mechanism. Each SBML Level 3 package is implemented in a separate code plug-in that can be enabled by the application to support working with that SBML package. A given SBML model may thus contain not only objects defined by SBML Level 3 Core, but also objects created by libSBML plug-ins supporting additional Level 3 packages.

Returns the XML namespace prefix of this element.
This reports the XML namespace prefix chosen for this class of object in the current SBML document. This may be an empty string if the component has no explicit prefix (for instance, if it is a core SBML object placed in the default SBML namespace of the document). If it is not empty, then it corresponds to the XML namespace prefix used set the object, whatever that may be in a given SBML document.

Returns the MIRIAM biological qualifier associated with the given resource.
In MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The latter kind is used to qualify the relationship between a model component and a biological entity which it represents. Examples of relationships include 'is' and 'has part', but many others are possible. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify biological annotations in the same standardized way. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM biological qualifiers are represented using valueswhose names begin with BQB_ in the interface class libsbml. This method searches the controlled-vocabulary annotations (i.e., the list of CVTerm objects) on the present object, then out of those that have biological qualifiers, looks for an annotation to the given resource. If such an annotation is found, it returns the type of biological qualifier associated with that resource as a valuewhose names begin with BQB_ in the interface class libsbml.
| resource | string representing the resource; e.g., 'http://www.geneontology.org/#GO:0005892'. |
BQB_ constants defined in libsbml may be expanded in later libSBML releases, to match the values defined by MIRIAM at that later time.

Returns the MIRIAM model qualifier associated with the given resource.
In MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The former kind is used to qualify the relationship between a model component and another modeling object. An example qualifier is 'isDerivedFrom', to indicate that a given component of the model is derived from the modeling object represented by the referenced resource. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify model annotations in the same standardized way. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM model qualifiers are represented using valueswhose names begin with BQB_ in the interface class libsbml.

Returns the SBMLDocument object containing this object instance.
LibSBML uses the class SBMLDocument as a top-level container for storing SBML content and data associated with it (such as warnings and error messages). An SBML model in libSBML is contained inside an SBMLDocument object. SBMLDocument corresponds roughly to the class SBML defined in the SBML Level 3 and Level 2 specifications, but it does not have a direct correspondence in SBML Level 1. (But, it is created by libSBML no matter whether the model is Level 1, Level 2 or Level 3.)
This method allows the caller to obtain the SBMLDocument for the current object.

Returns the integer portion of the value of the 'sboTerm' attribute of this object.
Beginning with SBML Level 2 Version 2, objects derived from SBase have an optional attribute named 'sboTerm' for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form 'SBO:NNNNNNN', where 'NNNNNNN' is a seven digit integer number; libSBML simplifies the representation by only storing the 'NNNNNNN' integer portion. Thus, in libSBML, the 'sboTerm' attribute on SBase has data type int, and SBO identifiers are stored simply as integers.
SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'. More details can be found in SBML specifications for Level 2 Version 2 and above.

| new int libsbmlcs.Event.getTypeCode | ( | ) |
Returns the libSBML type code of this object instance.
LibSBML attaches an identifying code to every kind of SBML object. These are integer constants known as SBML type codes. The names of all the codes begin with the characters SBML_. In the C# language interface for libSBML, the type codes are defined as static integer constants in the interface class libsbmlcs.libsbml.Note that different Level 3 package plug-ins may use overlapping type codes; to identify the package to which a given object belongs, call the SBase::getPackageName() method on the object.
The exception to this is lists: all SBML-style list elements have the type SBML_LIST_OF, regardless of what package they are from.

Gets the namespace URI to which this element belongs to.
For example, all elements that belong to SBML Level 3 Version 1 Core must would have the URI 'http://www.sbml.org/sbml/level3/version1/core'; all elements that belong to Layout Extension Version 1 for SBML Level 3 Version 1 Core must would have the URI 'http://www.sbml.org/sbml/level3/version1/layout/version1'.
This function first returns the URI for this element by looking into the SBMLNamespaces object of the document with the its package name. If not found, it will then look for the namespace associated with the element itself.
| bool libsbmlcs.Event.getUseValuesFromTriggerTime | ( | ) |
Get the value of the 'useValuesFromTriggerTime' attribute of this Event.
The optional Delay on Event and the fact that multiple events may be simultaneously executed means there are two times to consider when computing the results of an event: the time at which the event is triggered, and the time at which assignments are executed. It is also possible to distinguish between the time at which the EventAssignment's expression is calculated, and the time at which the assignment is made: the expression could be evaluated at the same time the assignments are performed, i.e., when the event is executed, but it could also be defined to be evaluated at the time the event is triggered.
In SBML Level 2 versions prior to Version 4, the semantics of Event time delays were defined such that the expressions in the event's assignments were always evaluated at the time the event was triggered. This definition made it difficult to define an event whose assignment formulas were meant to be evaluated at the time the event was executed (i.e., after the time period defined by the value of the Delay element, or after any other simultaneous event may have been executed and changed the model state). In SBML Level 2 Version 4, the attribute 'useValuesFromTriggerTime' on Event allows a model to indicate the time at which the event's assignments are intended to be evaluated. In SBML Level 2, the attribute has a default value of true, which corresponds to the interpretation of event assignments prior to Version 4: the values of the assignment formulas are computed at the moment the event is triggered, not after the delay. If 'useValuesFromTriggerTime'=false, it means that the formulas in the event's assignments are to be computed after the delay, at the time the event is executed. In SBML Level 3, the attribute is mandatory, not optional, and all events must specify a value for it.

Predicate returning true if this object's 'annotation' subelement exists and has content.
Whereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.
SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.

| new bool libsbmlcs.Event.isSetId | ( | ) |
Predicate returning true if this Event's 'id' attribute is set.
The identifier given by an object's 'id' attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier. The data type of 'id' is always SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows:
letter ::= 'a'..'z','A'..'Z' digit ::= '0'..'9' idChar ::= letter | digit | '_' SId ::= ( letter | '_' ) idChar*
The characters ( and ) are used for grouping, the character * 'zero or more times', and the character | indicates logical 'or'. The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.
Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined 'id' and 'name' attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have 'id' or 'name' attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: 'variable' (for the rules and event assignments), 'symbol' (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return false for objects of these classes.
With the addition of 'id' and 'name' attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original 'id' methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual 'id' attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an 'id' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write 'id' attributes for those objects.

Predicate returning true if this object's 'metaid' attribute is set.
The optional attribute named 'metaid', present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the 'metaid' attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the 'annotation' subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.

true if the ModelHistory of this object is set, false otherwise.| new bool libsbmlcs.Event.isSetName | ( | ) |
Predicate returning true if this Event's 'name' attribute is set.
In SBML Level 3 Version 2, the 'id' and 'name' attributes were moved to SBase directly, instead of being defined individually for many (but not all) objects. LibSBML has for a long time provided functions defined on SBase itself to get, set, and unset those attributes, which would fail or otherwise return empty strings if executed on any object for which those attributes were not defined. Now that all SBase objects define those attributes, those functions now succeed for any object with the appropriate level and version.
The 'name' attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of 'name' is the type string defined in XML Schema. SBML imposes no restrictions as to the content of 'name' attributes beyond those restrictions defined by the string type in XML Schema.
The recommended practice for handling 'name' is as follows. If a software tool has the capability for displaying the content of 'name' attributes, it should display this content to the user as a component's label instead of the component's 'id'. If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the 'name' attribute is missing on a given component, then the user interface should display the value of the 'id' attribute instead. (Script language interpreters are especially likely to display 'id' instead of 'name'.)
As a consequence of the above, authors of systems that automatically generate the values of 'id' attributes should be aware some systems may display the 'id''s to the user. Authors therefore may wish to take some care to have their software create 'id' values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the 'id' attribute be an abbreviated form of the name attribute value.
An additional point worth mentioning is although there are restrictions on the uniqueness of 'id' values, there are no restrictions on the uniqueness of 'name' values in a model. This allows software applications leeway in assigning component identifiers.
Regardless of the level and version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have names). If the object in question does not posess a 'name' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the name to be set, nor will it read or write 'name' attributes for those objects.

Predicate returning true if this object's 'notes' subelement exists and has content.
The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.
The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker::hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how 'notes' element content must be structured.

Replaces all uses of a given meta identifier attribute value with another value.
In SBML, object 'meta' identifiers are of the XML data type ID; the SBML object attribute itself is typically named metaid. All attributes that hold values referring to values of type ID are of the XML data type IDREF. They are also sometimes informally referred to as 'metaid refs', in analogy to the SBML-defined type SIdRef.
This method works by looking at all meta-identifier attribute values, comparing the identifiers to the value of oldid. If any matches are found, the matching identifiers are replaced with newid. The method does not descend into child elements.
| oldid | the old identifier. |
| newid | the new identifier. |

Replaces all uses of a given SIdRef type attribute value with another value.
In SBML, object identifiers are of a data type called SId. In SBML Level 3, an explicit data type called SIdRef was introduced for attribute values that refer to SId values; in previous Levels of SBML, this data type did not exist and attributes were simply described to as 'referring to an identifier', but the effective data type was the same as SIdRef in Level 3. These and other methods of libSBML refer to the type SIdRef for all Levels of SBML, even if the corresponding SBML specification did not explicitly name the data type.
This method works by looking at all attributes and (if appropriate) mathematical formulas in MathML content, comparing the referenced identifiers to the value of oldid. If any matches are found, the matching values are replaced with newid. The method does not descend into child elements.

Replaces all uses of a given UnitSIdRef type attribute value with another value.
In SBML, unit definitions have identifiers of type UnitSId. In SBML Level 3, an explicit data type called UnitSIdRef was introduced for attribute values that refer to UnitSId values; in previous Levels of SBML, this data type did not exist and attributes were simply described to as 'referring to a unit identifier', but the effective data type was the same as UnitSIdRef in Level 3. These and other methods of libSBML refer to the type UnitSIdRef for all Levels of SBML, even if the corresponding SBML specification did not explicitly name the data type.

Replaces the given top-level element within the 'annotation' subelement of this SBML object and with the annotation element supplied.
SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.
This method determines the name of the element to be replaced from the annotation argument. Functionally it is equivalent to calling removeTopLevelAnnotationElement(name) followed by calling appendAnnotation(annotation_with_name), with the exception that the placement of the annotation element remains the same.

The string sid is copied.
The identifier given by an object's 'id' attribute value is used to identify the object within the SBML model definition. Other objects can refer to the component using this identifier. The data type of 'id' is always SId or a type derived from that, such as UnitSId, depending on the object in question. All data types are defined as follows:
letter ::= 'a'..'z','A'..'Z' digit ::= '0'..'9' idChar ::= letter | digit | '_' SId ::= ( letter | '_' ) idChar*
The characters ( and ) are used for grouping, the character * 'zero or more times', and the character | indicates logical 'or'. The equality of SBML identifiers is determined by an exact character sequence match; i.e., comparisons must be performed in a case-sensitive manner. This applies to all uses of SId, SIdRef, and derived types.
Users need to be aware of some important API issues that are the result of the history of SBML and libSBML. Prior to SBML Level 3 Version 2, SBML defined 'id' and 'name' attributes on only a subset of SBML objects. To simplify the work of programmers, libSBML's API provided get, set, check, and unset on the SBase object class itself instead of on individual subobject classes. This made the get/set/etc. methods uniformly available on all objects in the libSBML API. LibSBML simply returned empty strings or otherwise did not act when the methods were applied to SBML objects that were not defined by the SBML specification to have 'id' or 'name' attributes. Additional complications arose with the rule and assignment objects: InitialAssignment, EventAssignment, AssignmentRule, and RateRule. In early versions of SBML, the rule object hierarchy was different, and in addition, then as now, they possess different attributes: 'variable' (for the rules and event assignments), 'symbol' (for initial assignments), or neither (for algebraic rules). Prior to SBML Level 3 Version 2, getId() would always return an empty string, and isSetId() would always return false for objects of these classes.
With the addition of 'id' and 'name' attributes on SBase in Level 3 Version 2, it became necessary to introduce a new way to interact with the attributes more consistently in libSBML to avoid breaking backward compatibility in the behavior of the original 'id' methods. For this reason, libSBML provides four functions (getIdAttribute(), setIdAttribute(), isSetIdAttribute(), and unsetIdAttribute()) that always act on the actual 'id' attribute inherited from SBase, regardless of the object's type. These new methods should be used instead of the older getId()/setId()/etc. methods unless the old behavior is somehow necessary. Regardless of the Level and Version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have identifiers). If the object in question does not posess an 'id' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the identifier to be set, nor will it read or write 'id' attributes for those objects.

Sets the value of the meta-identifier attribute of this SBML object.
The optional attribute named 'metaid', present on every major SBML component type, is for supporting metadata annotations using RDF (Resource Description Format). The attribute value has the data type XML ID, the XML identifier type, which means each 'metaid' value must be globally unique within an SBML file. The latter point is important, because the uniqueness criterion applies across any attribute with type ID anywhere in the file, not just the 'metaid' attribute used by SBML—something to be aware of if your application-specific XML content inside the 'annotation' subelement happens to use the XML ID type. Although SBML itself specifies the use of XML ID only for the 'metaid' attribute, SBML-compatible applications should be careful if they use XML ID's in XML portions of a model that are not defined by SBML, such as in the application-specific content of the 'annotation' subelement. Finally, note that LibSBML does not provide an explicit XML ID data type; it uses ordinary character strings, which is easier for applications to support.

Sets the value of the 'sboTerm' attribute.
Beginning with SBML Level 2 Version 2, objects derived from SBase have an optional attribute named 'sboTerm' for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form 'SBO:NNNNNNN', where 'NNNNNNN' is a seven digit integer number; libSBML simplifies the representation by only storing the 'NNNNNNN' integer portion. Thus, in libSBML, the 'sboTerm' attribute on SBase has data type int, and SBO identifiers are stored simply as integers.
SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'. More details can be found in SBML specifications for Level 2 Version 2 and above.

Sets the 'useValuesFromTriggerTime' attribute of this Event to a value.
The optional Delay on Event and the fact that multiple events may be simultaneously executed means there are two times to consider when computing the results of an event: the time at which the event is triggered, and the time at which assignments are executed. It is also possible to distinguish between the time at which the EventAssignment's expression is calculated, and the time at which the assignment is made: the expression could be evaluated at the same time the assignments are performed, i.e., when the event is executed, but it could also be defined to be evaluated at the time the event is triggered.
In SBML Level 2 versions prior to Version 4, the semantics of Event time delays were defined such that the expressions in the event's assignments were always evaluated at the time the event was triggered. This definition made it difficult to define an event whose assignment formulas were meant to be evaluated at the time the event was executed (i.e., after the time period defined by the value of the Delay element, or after any other simultaneous event may have been executed and changed the model state). In SBML Level 2 Version 4, the attribute 'useValuesFromTriggerTime' on Event allows a model to indicate the time at which the event's assignments are intended to be evaluated. In SBML Level 2, the attribute has a default value of true, which corresponds to the interpretation of event assignments prior to Version 4: the values of the assignment formulas are computed at the moment the event is triggered, not after the delay. If 'useValuesFromTriggerTime'=false, it means that the formulas in the event's assignments are to be computed after the delay, at the time the event is executed. In SBML Level 3, the attribute is mandatory, not optional, and all events must specify a value for it.

| new int libsbmlcs.Event.unsetName | ( | ) |
Unsets the value of the 'name' attribute of this Event.
In SBML Level 3 Version 2, the 'id' and 'name' attributes were moved to SBase directly, instead of being defined individually for many (but not all) objects. LibSBML has for a long time provided functions defined on SBase itself to get, set, and unset those attributes, which would fail or otherwise return empty strings if executed on any object for which those attributes were not defined. Now that all SBase objects define those attributes, those functions now succeed for any object with the appropriate level and version.
The 'name' attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of 'name' is the type string defined in XML Schema. SBML imposes no restrictions as to the content of 'name' attributes beyond those restrictions defined by the string type in XML Schema.
The recommended practice for handling 'name' is as follows. If a software tool has the capability for displaying the content of 'name' attributes, it should display this content to the user as a component's label instead of the component's 'id'. If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the 'name' attribute is missing on a given component, then the user interface should display the value of the 'id' attribute instead. (Script language interpreters are especially likely to display 'id' instead of 'name'.)
As a consequence of the above, authors of systems that automatically generate the values of 'id' attributes should be aware some systems may display the 'id''s to the user. Authors therefore may wish to take some care to have their software create 'id' values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the 'id' attribute be an abbreviated form of the name attribute value.
An additional point worth mentioning is although there are restrictions on the uniqueness of 'id' values, there are no restrictions on the uniqueness of 'name' values in a model. This allows software applications leeway in assigning component identifiers.
Regardless of the level and version of the SBML, these functions allow client applications to use more generalized code in some situations (for instance, when manipulating objects that are all known to have names). If the object in question does not posess a 'name' attribute according to the SBML specification for the Level and Version in use, libSBML will not allow the name to be set, nor will it read or write 'name' attributes for those objects.

In SBML Level 2 Version 4, the attribute 'useValuesFromTriggerTime' on Event allows a model to indicate the time at which the event's assignments are intended to be evaluated. In SBML Level 2, the attribute has a default value of true, which corresponds to the interpretation of event assignments prior to Version 4: the values of the assignment formulas are computed at the moment the event is triggered, not after the delay. If 'useValuesFromTriggerTime'=false, it means that the formulas in the event's assignments are to be computed after the delay, at the time the event is executed. In SBML Level 3, the attribute is mandatory, not optional, and all events must specify a value for it.
