Inheritance diagram for ScXMLEvaluator:

Public Member Functions
virtual void	clearTemporaryVariables (void)
virtual ScXMLDataObj *	evaluate (const char *expression) const =0
ScXMLStateMachine *	getStateMachine (void) const
virtual SoType	getTypeId (void) const =0
	Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.
virtual ScXMLDataObj *	locate (const char *location) const =0
virtual SbBool	setAtLocation (const char *location, ScXMLDataObj *obj)=0
virtual void	setStateMachine (ScXMLStateMachine *sm)
Public Member Functions inherited from ScXMLObject
SbBool	isOfType (SoType type) const
	Returns TRUE if the type of this object is either of the same type or inherited from type.

Static Public Member Functions
static void	cleanClass (void)
static SoType	getClassTypeId (void)
static void	initClass (void)
Static Public Member Functions inherited from ScXMLObject
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.
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.

Additional Inherited Members
Static Protected Member Functions inherited from ScXMLObject

Member Function Documentation

clearTemporaryVariables()

void ScXMLEvaluator::clearTemporaryVariables ( void )

virtual

Does nothing - overridden in derived classes.

The intention of this function is to clear out temporary variables that have the scope of only one event being processed by the scxml state machine.

Reimplemented in ScXMLCoinEvaluator, and ScXMLMinimumEvaluator.

evaluate()

ScXMLDataObj * ScXMLEvaluator::evaluate ( const char * expression ) const

pure virtual

Implemented in ScXMLMinimumEvaluator.

getTypeId()

virtual SoType ScXMLEvaluator::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 ScXMLCoinEvaluator, ScXMLECMAScriptEvaluator, ScXMLMinimumEvaluator, and ScXMLXPathEvaluator.

locate()

ScXMLDataObj * ScXMLEvaluator::locate ( const char * location ) const

pure virtual

Implemented in ScXMLMinimumEvaluator.

setAtLocation()

virtual SbBool ScXMLEvaluator::setAtLocation ( const char * location, ScXMLDataObj * obj )

pure virtual

Implemented in ScXMLMinimumEvaluator.

setStateMachine()

void ScXMLEvaluator::setStateMachine ( ScXMLStateMachine * sm )

virtual

Override to perform actions when installed on a state machine.

Reimplemented in ScXMLMinimumEvaluator, and ScXMLCoinEvaluator.
