A species in SBML refers to a pool of entities that (a) are considered indistinguishable from each other for the purposes of the model, (b) participate in reactions, and (c) are located in a specific compartment. The SBML Species object class is intended to represent these pools.
As with other major constructs in SBML, Species has a mandatory attribute, "id", used to give the species type an identifier in the model. The identifier must be a text string conforming to the identifer syntax permitted in SBML. Species also has an optional "name" attribute, of type string. The "id" and "name" must be used according to the guidelines described in the SBML specifications.
The required attribute "compartment" is used to identify the compartment in which the species is located. The attribute's value must be the identifier of an existing Compartment object. It is important to note that there is no default value for the "compartment" attribute on Species; every species in an SBML model must be assigned a compartment explicitly. (This also implies that every model with one or more Species objects must define at least one Compartment object.)
The optional attributes "initialAmount" and "initialConcentration", both having a data type of double, can be used to set the initial quantity of the species in the compartment where the species is located. These attributes are mutually exclusive; i.e., only one can have a value on any given instance of a Species object. Missing "initialAmount" and "initialConcentration" values implies that their values either are unknown, or to be obtained from an external source, or determined by an InitialAssignment or other SBML construct elsewhere in the model.
A species' initial quantity in SBML is set by the "initialAmount" or "initialConcentration" attribute exactly once. If the "constant" attribute is true, then the value of the species' quantity is fixed and cannot be changed except by an InitialAssignment. These methods differ in that the "initialAmount" and "initialConcentration" attributes can only be used to set the species quantity to a literal floating-point number, whereas the use of an InitialAssignment object allows the value to be set using an arbitrary mathematical expression (which, thanks to MathML's expressiveness, may evaluate to a rational number). If the species' "constant" attribute is false, the species' quantity value may be overridden by an InitialAssignment or changed by AssignmentRule or AlgebraicRule, and in addition, for t > 0, it may also be changed by a RateRule, Event objects, and as a result of being a reactant or product in one or more Reaction objects. (However, some constructs are mutually exclusive; see the SBML specifications for the precise details.) It is not an error to define "initialAmount" or "initialConcentration" on a species and also redefine the value using an InitialAssignment, but the "initialAmount" or "initialConcentration" setting in that case is ignored. The SBML specifications provide additional information about the semantics of assignments, rules and values for simulation time t 
0.
SBML Level 2 additionally stipulates that in cases where a species' compartment has a "spatialDimensions" value of 0 (zero), the species cannot have a value for "initialConcentration" because the concepts of concentration and density break down when a container has zero dimensions.
When the attribute "initialAmount" is set, the unit of measurement associated with the value of "initialAmount" is specified by the Species attribute "substanceUnits". When the "initialConcentration" attribute is set, the unit of measurement associated with this concentration value is {unit of amount} divided by {unit of size}, where the {unit of amount} is specified by the Species "substanceUnits" attribute, and the {unit of size} is specified by the "units" attribute of the Compartment object in which the species is located. Note that in either case, a unit of amount is involved and determined by the "substanceUnits" attribute. Note these two attributes alone do not determine the units of the species when the species identifier appears in a mathematical expression; that aspect is determined by the attribute "hasOnlySubstanceUnits" discussed below.
In SBML Level 3, if the "substanceUnits" attribute is not set on a given Species object instance, then the unit of amount for that species is inherited from the "substanceUnits" attribute on the enclosing Model object instance. If that attribute on Model is not set either, then the unit associated with the species' quantity is undefined.
In SBML Level 2, if the "substanceUnits" attribute is not set on a given Species object instance, then the unit of amount for that species is taken from the predefined SBML unit identifier "substance". The value assigned to "substanceUnits" must be chosen from one of the following possibilities: one of the base unit identifiers defined in SBML, the built-in unit identifier "substance", or the identifier of a new unit defined in the list of unit definitions in the enclosing Model object. The chosen units for "substanceUnits" must be be "dimensionless", "mole", "item", "kilogram", "gram", or units derived from these.
As noted at the beginning of this section, simply setting "initialAmount" or "initialConcentration" alone does not determine whether a species identifier represents an amount or a concentration when it appears elsewhere in an SBML model. The role of the attribute "hasOnlySubstanceUnits" is to indicate whether the units of the species, when the species identifier appears in mathematical formulas, are intended to be concentration or amount. The attribute takes on a boolean value. In SBML Level 3, the attribute has no default value and must always be set in a model; in SBML Level 2, it has a default value of false.
The units of the species are used in the following ways:
When the species' identifier appears in a MathML formula, it represents the species' quantity, and the unit of measurement associated with the quantity is as described above.
The "math" elements of AssignmentRule, InitialAssignment and EventAssignment objects referring to this species should all have the same units as the unit of measurement associated with the species quantity.
In a RateRule object that defines the rate of change of the species' quantity, the unit associated with the rule's "math" element should be equal to the unit of the species' quantity divided by the model-wide unit of time; in other words, {unit of species quantity}/{unit of time}.
The Species object class has two boolean attributes named "constant" and "boundaryCondition", used to indicate whether and how the quantity of that species can vary during a simulation. In SBML Level 2 they are optional; in SBML Level 3 they are mandatory. The following table shows how to interpret the combined values of these attributes.

By default, when a species is a product or reactant of one or more reactions, its quantity is determined by those reactions. In SBML, it is possible to indicate that a given species' quantity is not determined by the set of reactions even when that species occurs as a product or reactant; i.e., the species is on the boundary of the reaction system, and its quantity is not determined by the reactions. The boolean attribute "boundaryCondition" can be used to indicate this. A value of false indicates that the species is part of the reaction system. In SBML Level 2, the attribute has a default value of false, while in SBML Level 3, it has no default.
The "constant" attribute indicates whether the species' quantity can be changed at all, regardless of whether by reactions, rules, or constructs other than InitialAssignment. A value of false indicates that the species' quantity can be changed. (This is also a common value because the purpose of most simulations is precisely to calculate changes in species quantities.) In SBML Level 2, the attribute has a default value of false, while in SBML Level 3, it has no default. Note that the initial quantity of a species can be set by an InitialAssignment irrespective of the value of the "constant" attribute.
In practice, a "boundaryCondition" value of true means a differential equation derived from the reaction definitions should not be generated for the species. However, the species' quantity may still be changed by AssignmentRule, RateRule, AlgebraicRule, Event, and InitialAssignment constructs if its "constant" attribute is false. Conversely, if the species' "constant" attribute is true, then its value cannot be changed by anything except InitialAssignment.
A species having "boundaryCondition"=false and "constant"=false can appear as a product and/or reactant of one or more reactions in the model. If the species is a reactant or product of a reaction, it must not also appear as the target of any AssignmentRule or RateRule object in the model. If instead the species has "boundaryCondition"= false and "constant"=true, then it cannot appear as a reactant or product, or as the target of any AssignmentRule, RateRule or EventAssignment object in the model.
Finally, it is worth clarifying that while the constant and boundaryCondition attributes restrict whether and how the species amount changes, the same is not true of a species' concentration. In SBML, the concentration of a species is a quantity that depends on the size of the compartment in which it is located. A compartment's size may change, and therefore, so can the concentration of a species even if the amount of the species remains unchanged. A species' concentration may therefore vary even if the Species object's constant attribute is set to true in a model.
In SBML Level 3, Species has an additional optional attribute, "conversionFactor", that defines a conversion factor that applies to a particular species. The value must be the identifier of a Parameter object instance defined in the model. That Parameter object must be a constant, meaning its "constant" attribute must be set to true. If a given Species object definition defines a value for its "conversionFactor" attribute, it takes precedence over any factor defined by the Model object's "conversionFactor" attribute.
The unit of measurement associated with a species' quantity can be different from the unit of extent of reactions in the model. SBML Level 3 avoids implicit unit conversions by providing an explicit way to indicate any unit conversion that might be required. The use of a conversion factor in computing the effects of reactions on a species' quantity is explained in detail in the SBML Level 3 specification document. Because the value of the "conversionFactor" attribute is the identifier of a Parameter object, and because parameters can have units attached to them, the transformation from reaction extent units to species units can be completely specified using this approach.
Note that the unit conversion factor is only applied when calculating the effect of a reaction on a species. It is not used in any rules or other SBML constructs that affect the species, and it is also not used when the value of the species is referenced in a mathematical expression.
In SBML Level 2 Versions 2–4, each species in a model may optionally be designated as belonging to a particular species type. The optional attribute "speciesType" is used to identify the species type of the chemical entities that make up the pool represented by the Species objects. The attribute's value must be the identifier of an existing SpeciesType object in the model. If the "speciesType" attribute is not present on a particular species definition, it means the pool contains chemical entities of a type unique to that pool; in effect, a virtual species type is assumed for that species, and no other species can belong to that species type. The value of "speciesType" attributes on species have no effect on the numerical interpretation of a model; simulators and other numerical analysis software may ignore "speciesType" attributes.
There can be only one species of a given species type in any given compartment of a model. More specifically, for all Species objects having a value for the "speciesType" attribute, the pair
must be unique across the set of all Species object in a model.
In versions of SBML Level 2 before Version 3, the class Species included an attribute called "spatialSizeUnits", which allowed explicitly setting the units of size for initial concentration. LibSBML retains this attribute for compatibility with older definitions of Level 2, but its use is strongly discouraged because many software tools do no properly interpret this unit declaration and it is incompatible with all SBML specifications after Level 2 Version 3.
Species are unique in SBML in that they have a kind of duality: a species identifier may stand for either substance amount (meaning, a count of the number of individual entities) or a concentration or density (meaning, amount divided by a compartment size). The previous sections explain the meaning of a species identifier when it is referenced in a mathematical formula or in rules or other SBML constructs; however, it remains to specify what happens to a species when the compartment in which it is located changes in size.
When a species definition has a "hasOnlySubstanceUnits" attribute value of false and the size of the compartment in which the species is located changes, the default in SBML is to assume that it is the concentration that must be updated to account for the size change. This follows from the principle that, all other things held constant, if a compartment simply changes in size, the size change does not in itself cause an increase or decrease in the number of entities of any species in that compartment. In a sense, the default is that the amount of a species is preserved across compartment size changes. Upon such size changes, the value of the concentration or density must be recalculated from the simple relationship concentration = amount / size if the value of the concentration is needed (for example, if the species identifier appears in a mathematical formula or is otherwise referenced in an SBML construct). There is one exception: if the species' quantity is determined by an AssignmentRule, RateRule, AlgebraicRule, or an EventAssignment and the species has a "hasOnlySubstanceUnits" attribute value of false, it means that the concentration is assigned by the rule or event; in that case, the amount must be calculated when the compartment size changes. (Events also require additional care in this situation, because an event with multiple assignments could conceivably reassign both a species quantity and a compartment size simultaneously. Please refer to the SBML specifications for the details.)
Note that the above only matters if a species has a "hasOnlySubstanceUnits" attribute value of false, meaning that the species identifier refers to a concentration wherever the identifier appears in a mathematical formula. If instead the attribute's value is true, then the identifier of the species always stands for an amount wherever it appears in a mathematical formula or is referenced by an SBML construct. In that case, there is never a question about whether an assignment or event is meant to affect the amount or concentration: it is always the amount.
A particularly confusing situation can occur when the species has "constant" attribute value of true in combination with a "hasOnlySubstanceUnits" attribute value of false. Suppose this species is given a value for "initialConcentration". Does a "constant" value of true mean that the concentration is held constant if the compartment size changes? No; it is still the amount that is kept constant across a compartment size change. The fact that the species was initialized using a concentration value is irrelevant.

Appends the given annotation to the "annotation" subelement of this object.
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.

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:

| pkgPrefix | the XML prefix of the package. |

| UnitDefinition * Species::getDerivedUnitDefinition | ( | ) |
Constructs and returns a UnitDefinition that corresponds to the units of this Species' amount or concentration.
Species in SBML have an attribute ("substanceUnits") for declaring the units of measurement intended for the species' amount or concentration (depending on which one applies). In the absence of a value given for "substanceUnits", the units are taken from the enclosing Model's definition of "substance" or "substance"/(size of the compartment) in which the species is located, or finally, if these are not redefined by the Model, the relevant SBML default units for those quantities. Following that procedure, the method getDerivedUnitDefinition() returns a UnitDefinition based on the interpreted units of this species's amount or concentration.
Note that the functionality that facilitates unit analysis depends on the model as a whole. Thus, in cases where the object has not been added to a model or the model itself is incomplete, unit analysis is not possible and this method will return NULL.
Note also that unit declarations for Species are in terms of the identifier of a unit, but this method returns a UnitDefinition object, not a unit identifier. It does this by constructing an appropriate UnitDefinition. Callers may find this particularly useful when used in conjunction with the helper methods on UnitDefinition for comparing different UnitDefinition objects.
In SBML Level 2 specifications prior to Version 3, Species includes an additional attribute named "spatialSizeUnits", which allows explicitly setting the units of size for initial concentration. The getDerivedUnitDefinition() takes this into account for models expressed in SBML Level 2 Versions 1 and 2.

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.

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 value of the "metaid" attribute of this SBML object.
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 value of the "name" attribute of this Species object.
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 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.

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 values from the enumeration type BiolQualifierType_t.
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 value from the enumeration type BiolQualifierType_t.

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.

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).

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.

Removes this object from its parent.
If the parent was storing this object as a pointer, it is deleted. If not, it is simply cleared (as in ListOf objects). This is a pure virtual method, as every SBase element has different parents, and therefore different methods of removing itself. Will fail (and not delete itself) if it has no parent object. This function is designed to be overridden, but for all objects whose parent is of the class ListOf, the default implementation will work.

Replaces all uses of a given meta identifier attribute value with another value.
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.

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.

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.

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.

Unsets the value of the "name" attribute of this Species object.
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.
Reimplemented from SBase.

Unsets the value of the "notes" subelement of this SBML object.
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.
