Detailed Description

base class for all SCXML elements. This is a common base class for all SCXML document element classes. It manages XML attributes at the generic level, has utilities for checking document containment, and provides some infrastructure hooks.

  virtual SoType ScXMLElt::getTypeId (void) const [pure virtual]

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and 'downward' casting.

    SoBase::getTypeId() const

Implements ScXMLObject.

Implemented in ScXMLExecutableElt, ScXMLAbstractStateElt, ScXMLValidateElt, ScXMLTransitionElt, ScXMLStateElt, ScXMLSendElt, ScXMLScxmlElt, ScXMLScriptElt, ScXMLParamElt, ScXMLParallelElt, ScXMLOnExitElt, ScXMLOnEntryElt, ScXMLLogElt, ScXMLInvokeElt, ScXMLInitialElt, ScXMLIfElt, ScXMLHistoryElt, ScXMLFinalizeElt, ScXMLFinalElt, ScXMLEventElt, ScXMLElseIfElt, ScXMLElseElt, ScXMLDataModelElt, ScXMLDataElt, ScXMLContentElt, ScXMLAssignElt, and ScXMLAnchorElt.

  void ScXMLElt::setXMLAttribute (const char * attribute, const char * value)
This method associates a value with an attribute name. This is used for parameter passing while reading by the SCXML reader, but can be used as a general-purpose attribute dictionary outside of that.

If NULL is passed as the value, the attribute is removed.

  const char * ScXMLElt::getXMLAttribute (const char * attribute) const
This method returns the string value set for an attribute, or NULL if not set.

  SbBool ScXMLElt::handleXMLAttributes (void) [virtual]
This method is called when the file reader has set all the XML attributes on the object, and wants the object to handle them and report if the values were OK or if a read error should be produced.

Returns
    TRUE if the attributes are OK, and FALSE on error.

This base class implementation does nothing and just returns TRUE.

Reimplemented in ScXMLValidateElt, ScXMLTransitionElt, ScXMLStateElt, ScXMLSendElt, ScXMLScxmlElt, ScXMLParamElt, ScXMLParallelElt, ScXMLLogElt, ScXMLInvokeElt, ScXMLIfElt, ScXMLHistoryElt, ScXMLEventElt, ScXMLElseIfElt, ScXMLDataModelElt, ScXMLDataElt, ScXMLAssignElt, ScXMLAnchorElt, and ScXMLAbstractStateElt.

  const ScXMLElt * ScXMLElt::search (const char * attrname, const char * attrvalue) const [virtual]
This method searches the SCXML structure for an element with the given attribute value for the given attribute.

Returns NULL if nothing was found.

This function needs to be reimplemented to traverse child elements.

Reimplemented in ScXMLValidateElt, ScXMLTransitionElt, ScXMLStateElt, ScXMLSendElt, ScXMLScxmlElt, ScXMLParamElt, ScXMLParallelElt, ScXMLOnExitElt, ScXMLOnEntryElt, ScXMLLogElt, ScXMLInvokeElt, ScXMLInitialElt, ScXMLIfElt, ScXMLHistoryElt, ScXMLFinalElt, ScXMLEventElt, ScXMLElseIfElt, ScXMLDataModelElt, ScXMLDataElt, ScXMLAssignElt, ScXMLAnchorElt, and ScXMLAbstractStateElt.

  ScXMLElt * ScXMLElt::clone (void) const
Returns a deep copy of the given SCXML element.

  void ScXMLElt::setContainer (ScXMLElt * container) [virtual]
Set the pointer to the parent ScXML object.

  SbBool ScXMLElt::isContainedIn (const ScXMLElt * element) const
This method returns TRUE if the object is contained within the given object argument. Also if they are the same, TRUE will be returned. Otherwise, FALSE is returned.
