An Event object defines when the event can occur, the variables that are affected by the event, and how the variables are affected. The effect of the event can optionally be delayed after the occurrence of the condition which invokes it. An event delay is defined using an object of class Delay.
The object class Delay is derived from SBase and adds a single subelement called 'math'. This subelement is used to hold MathML content. The mathematical formula represented by 'math' must evaluate to a numerical value. It is used as the length of time between when the event has fired and when the event's assignments are actually executed. If no delay is present on a given Event, a time delay of zero is assumed.
The expression in 'math' must be evaluated at the time the rule is fired. The expression must always evaluate to a positive number (otherwise, a nonsensical situation could arise where an event is defined to fire before it is triggered!).
time units in the model). Depending on which Version of SBML Level 2 is in use, libSBML may or may not flag unit inconsistencies as errors or just warnings.Note that units are not predefined or assumed for the contents of 'math' in a Delay object; rather, they must be defined explicitly for each instance of a Delay object in a model. This is an important point to bear in mind when literal numbers are used in delay expressions. For example, the following Event instance would result in a warning logged by SBMLDocument.checkConsistency() about the fact that libSBML cannot verify the consistency of the units of the expression. The reason is that the formula inside the 'math' element does not have any declared units, whereas what is expected in this context is units of time:
<model>
...
<listOfEvents>
<event>
...
<delay>
<math xmlns='http://www.w3.org/1998/Math/MathML'>
<cn> 1 </cn>
</math>
</delay>
...
</event>
</listOfEvents>
...
</model>
The <cn> 1 </cn> within the mathematical formula of the delay above has no units declared. To make the expression have the needed units of time, literal numbers should be avoided in favor of defining Parameter objects for each quantity, and declaring units for the Parameter values. The following fragment of SBML illustrates this approach:
<model>
...
<listOfParameters>
<parameter id='transcriptionDelay' value='10' units='time'/>
</listOfParameters>
...
<listOfEvents>
<event>
...
<delay>
<math xmlns='http://www.w3.org/1998/Math/MathML'>
<ci> transcriptionDelay </ci>
</math>
</delay>
...
</event>
</listOfEvents>
...
</model>

int
Appends the annotation content given by annotation to any existing content in 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.
Unlike SBase.setAnnotation(const XMLNode* annotation) or SBase.setAnnotation(const std.string& annotation), this method allows other annotations to be preserved when an application adds its own data.
Some words of explanation about the
set/unset/isSet methods:
SBML Levels 1 and 2 define certain attributes on some classes of objects as
optional. This requires an application to be careful about the distinction
between two cases: (1) a given attribute has never been set to a
value, and therefore should be assumed to have the SBML-defined default
value, and (2) a given attribute has been set to a value, but the value
happens to be an empty string. LibSBML supports these distinctions by
providing methods to set, unset, and query the status of attributes that
are optional. The methods have names of the form
setAttribute(...),
unsetAttribute(), and
isSetAttribute(), where Attribute
is the the name of the optional attribute in question.

Appends notes content to the 'notes' element attached to this object.

The optional 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. The SBML Level 2 specification has considerable detail about how 'notes' element content must be handled; please refer to the specifications.

Python method signature(s):
containsUndeclaredUnits(self)bool containsUndeclaredUnits(self)
bool
Predicate returning true or false depending on whether the 'math' expression in this Delay instance contains parameters with undeclared units or literal numbers.
Delay elements in SBML express a time delay for an Event. Beginning with SBML Level 2 Version 2, the units of that time are calculated based on the mathematical expression and the model quantities referenced by <ci> elements used within that expression. The Delay.getDerivedUnitDefinition() method returns what libSBML computes the units to be, to the extent that libSBML can compute them. However, if the expression contains literal numbers or parameters with undeclared units, libSBML may not be able to compute the full units of the expression and will only return what it can compute. Callers should always use Delay.containsUndeclaredUnits() when using Delay.getDerivedUnitDefinition() to decide whether the returned units may be incomplete.

Delay elements in SBML express a time delay for an Event.

The Delay.getDerivedUnitDefinition() method returns what libSBML computes the units to be, to the extent that libSBML can compute them.
(Prior to SBML Level 2 Version 2, there existed an attribute on Event called 'timeUnits'. This attribute could be used to set the intended units of the delay expression. For such models, this will return a UnitDefinition object that corresponds to the declared 'timeUnits' units.)
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.

SBML Levels 1 and 2 define certain attributes on some classes of objects as

between two cases: (1) a given attribute has never been set to a

value, and (2) a given attribute has been set to a value, but the value
happens to be an empty string. LibSBML supports these distinctions by
providing methods to set, unset, and query the status of attributes that

Python method signature(s):
setAnnotation(self, XMLNode annotation)int setAnnotation(self, string annotation)
int
Sets the value of the 'annotation' subelement of this SBML object to a copy of annotation given as a character string.
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.
Call this method will result in any existing content of the 'annotation' subelement to be discarded. Unless you have taken steps to first copy and reconstitute any existing annotations into the annotation that is about to be assigned, it is likely that performing such wholesale replacement is unfriendly towards other software applications whose annotations are discarded. An alternative may be to use SBase.appendAnnotation(const XMLNode* annotation) or SBase.appendAnnotation(const std.string& annotation).

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'. Please consult the SBML Level 2 Version 4 specification for more information about the use of SBO and the 'sboTerm' attribute.
