Detailed Description

LibSBML implementation of SBML's Constraint construct.

The Constraint object class was introduced in SBML Level 2 Version 2 as a mechanism for stating the assumptions under which a model is designed to operate. The constraints are statements about permissible values of different quantities in a model. Constraints are not used to compute dynamical values for simulation or analysis, but rather, they serve an advisory role for simulation/analysis tools.

SBML's Constraint object class has one required attribute, 'id', to give the parameter a unique identifier by which other parts of an SBML model definition can refer to it. A Constraint object can also have an optional 'name' attribute of type string. Identifiers and names must be used according to the guidelines described in the SBML specification (e.g., Section 3.3 in the Level 2 Version 4 specification).

Constraint has one required subelement, 'math', containing a MathML formula defining the condition of the constraint. This formula must return a boolean value of true when the model is a valid state. The formula can be an arbitrary expression referencing the variables and other entities in an SBML model. The evaluation of 'math' and behavior of constraints are described in more detail below.

A Constraint structure also has an optional subelement called 'message'. This can contain a message in XHTML format that may be displayed to the user when the condition of the formula in the 'math' subelement evaluates to a value of false. Software tools are not required to display the message, but it is recommended that they do so as a matter of best practice. The XHTML content within a 'message' subelement must follow the same restrictions as for the 'notes' element on SBase described in in the SBML Level 2 specification. For example, 'message' must not contain an XML declaration or a DOCTYPE declaration, and the permitted content can only take one of the following general forms: (1) a complete XHTML document beginning with the element <html> and ending with </xhtml>; (2) the body portion of a document beginning with the element <body> and ending with </body>; or (3) XHTML content that is permitted within a <body> ... </body> elements. The appendix of the SBML Level 2 Version 4 specification document describes one approach to reading the 'message' subelement content.

Constraint was introduced in SBML Level 2 Version 2. It is not available in earlier versions of Level 2 nor in any version of Level 1.

Semantics of Constraints

In the context of a simulation, a Constraint has effect at all times t >= 0. Each Constraint's 'math' subelement is first evaluated after any InitialAssignment definitions in a model at t = 0 and can conceivably trigger at that point. (In other words, a simulation could fail a constraint immediately.)

Constraint structures cannot and should not be used to compute the dynamical behavior of a model as part of, for example, simulation. Constraints may be used as input to non-dynamical analysis, for instance by expressing flux constraints for flux balance analysis.

The results of a simulation of a model containing a constraint are invalid from any simulation time at and after a point when the function given by the 'math' subelement returns a value of false. Invalid simulation results do not make a prediction of the behavior of the biochemical reaction network represented by the model. The precise behavior of simulation tools is left undefined with respect to constraints. If invalid results are detected with respect to a given constraint, the 'message' subelement may optionally be displayed to the user. The simulation tool may also halt the simulation or clearly delimit in output data the simulation time point at which the simulation results become invalid.

SBML does not impose restrictions on duplicate Constraint definitions or the order of evaluation of Constraint objects in a model. It is possible for a model to define multiple constraints all with the same mathematical expression. Since the failure of any constraint indicates that the model simulation has entered an invalid state, a system is not required to attempt to detect whether other constraints in the model have failed once any one constraint has failed.

def libsbml.SBase.addCVTerm (   self,
  args 
) [inherited]

Python method signature(s): 

addCVTerm(self, CVTerm term)    int

Adds a copy of the given CVTerm to this SBML object.

Parameters:
term the CVTerm to assign
Returns:
integer value indicating success/failure of the function. The possible values returned by this function are:
  • LIBSBML_OPERATION_SUCCESS
  • LIBSBML_OPERATION_FAILED
  • LIBSBML_UNEXPECTED_ATTRIBUTE
  • LIBSBML_INVALID_OBJECT
Note:
Since the CV Term uses the metaid of the object as a reference, if the object has no metaid set the CVTerm will not be added.
Warning:
The fact that this method copies the object passed to it means that the caller will be left holding a physically different object instance than the one contained in this object. Changes made to the original object instance (such as resetting attribute values) will not affect the instance added here. In addition, the caller should make sure to free the original object if it is no longer being used, or else a memory leak will result.

def libsbml.SBase.appendAnnotation (   self,
  args 
) [inherited]

Python method signature(s): 

appendAnnotation(self, XMLNode annotation)    int
appendAnnotation(self, string annotation)    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.

Parameters:
annotation an XML string that is to be copied and appended to the content of the 'annotation' subelement of this object
Returns:
integer value indicating success/failure of the function. The possible values returned by this function are:
  • LIBSBML_OPERATION_SUCCESS
  • LIBSBML_OPERATION_FAILED

def libsbml.SBase.appendNotes (   self,
  args 
) [inherited]

Python method signature(s): 

appendNotes(self, XMLNode notes)    int
appendNotes(self, string notes)    int

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

The content in notes is copied.

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.

Parameters:
notes an XML string that is to appended to the content of the 'notes' subelement of this object
Returns:
integer value indicating success/failure of the function. The possible values returned by this function are:
  • LIBSBML_OPERATION_SUCCESS
  • LIBSBML_INVALID_OBJECT
  • LIBSBML_OPERATION_FAILED

def libsbml.SBase.getAncestorOfType (   self,
  args 
) [inherited]

Python method signature(s): 

getAncestorOfType(self, SBMLTypeCode_t type)    SBase

Returns the ancestor SBML object that corresponds to the given SBMLTypeCode_t.

This function allows any object to determine its exact location/function within a model. For example a StoichiometryMath object has ancestors of type SpeciesReference, ListOfProducts/ListOfReactants/ListOfModifiers, Reaction, ListOfReactions and Model; any of which can be accessed via this function.

Parameters:
type the SBMLTypeCode_t of the ancestor to be returned.
Returns:
the ancestor SBML object of this SBML object, that corresponds to the given SBMLTypeCode_t, NULL if none exists.

Definition at line 2115 of file libsbml.py.

def libsbml.SBase.getAnnotation (   self  )  [inherited]

Python method signature(s): 

getAnnotation(self)    XMLNode

Returns the content of the 'annotation' subelement of this object as an XML node tree.

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.

The annotations returned by this method will be in XML form. LibSBML provides an object model and related interfaces for certain specific kinds of annotations, namely model history information and RDF content. See the ModelHistory, CVTerm and RDFAnnotationParser classes for more information about the facilities available.

Returns:
the annotation of this SBML object as an XMLNode

def libsbml.SBase.getAnnotationString (   self  )  [inherited]

Python method signature(s): 

getAnnotationString(self)    string

Returns the content of the 'annotation' subelement of this object 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.

Reimplemented from libsbml.SBase.

Definition at line 17816 of file libsbml.py.

def libsbml.SBase.getId (   self  )  [inherited]

Python method signature(s): 

getId(self)    string

Returns the value of the 'metaid' attribute of this 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. (Importantly, this uniqueness criterion applies across any attribute with type XML ID, 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 XML ID.) The 'metaid' value serves to identify a model component for purposes such as referencing that component from metadata placed within 'annotation' subelements.

Returns:
the metaid of this SBML object.

Returns the ModelQualifier associated with this resource, or BQM_UNKNOWN if the resource does not exist.

Parameters:
resource string representing the resource; e.g., 'http://www.geneontology.org/GO:0005892'
Returns:

Definition at line 3100 of file libsbml.py.

def libsbml.SBase.getSBMLDocument (   self,
  args 
) [inherited]

Python method signature(s): 

getSBMLDocument(self)    SBMLDocument
getSBMLDocument(self)    SBMLDocument

Returns the parent SBMLDocument 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 2 specification, 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 or Level 2.)

This method allows the SBMLDocument for the current object to be retrieved.

Returns:
the parent SBMLDocument object of this SBML object.

Definition at line 2068 of file libsbml.py.

def libsbml.SBase.getSBOTerm (   self  )  [inherited]

Python method signature(s): 

getSBOTerm(self)    int

Returns the integer portion of the value of the 'sboTerm' attribute of this object.

In SBML Level 2 Versions 2, 3 and 4, 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'. Please consult the SBML Level 2 Version 4 specification for more information about the use of SBO and the 'sboTerm' attribute.

Returns:
the value of the 'sboTerm' attribute as an integer, or -1 if the value is not set.

Definition at line 2141 of file libsbml.py.

def libsbml.SBase.getSBOTermID (   self  )  [inherited]

Python method signature(s): 

getSBOTermID(self)    string

Returns the string representation of the 'sboTerm' attribute of this object.

In SBML Level 2 Versions 2, 3 and 4, 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. This function recreates the string representation from the stored value. 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.

Returns:
the value of the 'sboTerm' attribute as a string of the form SBO:NNNNNNN, or an empty string if the value is not set.

def libsbml.Constraint.getTypeCode (   self  ) 

Python method signature(s): 

getTypeCode(self)    SBMLTypeCode_t

def libsbml.SBase.isSetAnnotation (   self  )  [inherited]

Python method signature(s): 

isSetAnnotation(self)    bool

Predicate returning true or false depending on whether 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.

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.

Returns:
true if a 'annotation' subelement exists, false otherwise.

def libsbml.SBase.isSetId (   self  )  [inherited]

Python method signature(s): 

isSetId(self)    bool

Predicate returning true or false depending on whether this object's 'metaid' attribute has been 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. (Importantly, this uniqueness criterion applies across any attribute with type XML ID, 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 XML ID.) The 'metaid' value serves to identify a model component for purposes such as referencing that component from metadata placed within 'annotation' subelements.

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.

def libsbml.SBase.setAnnotation (   self,
  args

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).

Sets the value of the 'sboTerm' attribute.

In SBML Level 2 Versions 2, 3 and 4, the data type of the SBML 'sboTerm' 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'. Please consult the SBML Level 2 Version 4 specification for more information about the use of SBO and the 'sboTerm' attribute.

def libsbml.SBase.toSBML (   self  )  [inherited]

Python method signature(s): 

toSBML(self)    char

Returns a string that consists of the partial SBML describing this object. This is primarily provided for testing and debugging purposes. It may be removed in a future version of libSBML.

Returns:
the partial SBML that describes this SBML object.

def libsbml.SBase.unsetAnnotation (   self  )  [inherited]

Python method signature(s): 

unsetAnnotation(self)    int

Unsets the value of the 'annotation' subelement of this SBML 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.

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.

Returns:
integer value indicating success/failure of the function. The possible values returned by this function are:
  • LIBSBML_OPERATION_SUCCESS

def libsbml.SBase.unsetCVTerms (   self  )  [inherited]

Python method signature(s): 

unsetCVTerms(self)    int

Clears the list of CVTerms of this SBML object.

Returns:
integer value indicating success/failure of the function. The possible values returned by this function are:
  • LIBSBML_OPERATION_SUCCESS
  • LIBSBML_OPERATION_FAILED

def libsbml.Constraint.unsetMessage (   self  ) 

Python method signature(s): 

unsetMessage(self)    int

Unsets the 'message' subelement of this Constraint.

def libsbml.SBase.unsetMetaId (   self  )  [inherited]

Python method signature(s): 

unsetMetaId(self)    int

Unsets 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. (Importantly, this uniqueness criterion applies across any attribute with type XML ID, 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 XML ID.) The 'metaid' value serves to identify a model component for purposes such as referencing that component from metadata placed within 'annotation' subelements.

def libsbml.SBase.unsetNotes (   self  )  [inherited]

Python method signature(s): 

unsetNotes(self)    int

Unsets the value of the 'notes' subelement of this SBML 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.
