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 run-time type checking and 'downward' casting.

SoBase::getTypeId() const

Implements ScXMLObject.

Implemented in ScXMLXPathEvaluator, ScXMLMinimumEvaluator, ScXMLECMAScriptEvaluator, and ScXMLCoinEvaluator.

void ScXMLEvaluator::setStateMachine (ScXMLStateMachine * sm) [virtual]

Override to perform actions when installed on a state machine.

Reimplemented in ScXMLCoinEvaluator, and ScXMLMinimumEvaluator.

void ScXMLEvaluator::clearTemporaryVariables (void) [virtual]

Does nothing - overridden in derived classes.

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

Reimplemented in ScXMLMinimumEvaluator, and ScXMLCoinEvaluator.
