Public Member Functions

Returns TRUE if the type of this object is either of the same type or inherited from type.

Static Public Member Functions inherited from ScXMLObject
static SoType getClassTypeId (void)
This static method returns the SoType object associated with objects of this class.
static void initClass (void)
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.
static void cleanClass (void)
Does the opposite of initClass, deallocates any class specific resources and resets the class to an uninitialized state with respect to the Coin type system.

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.

Since: Coin 3.1

Member Function Documentation

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.

See also: SoBase::getTypeId() const

Implements ScXMLObject.

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

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

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