virtual \fBSoType\fP ScXMLEvaluator::getTypeId (void) const\fC [pure virtual]\fP

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

See also:

SoBase::getTypeId() const

Implements ScXMLObject.

Implemented in ScXMLCoinEvaluator, ScXMLECMAScriptEvaluator, ScXMLMinimumEvaluator, and ScXMLXPathEvaluator.

void ScXMLEvaluator::setStateMachine (\fBScXMLStateMachine\fP *sm)\fC [virtual]\fP

Override to perform actions when installed on a state machine.

Reimplemented in ScXMLCoinEvaluator, and ScXMLMinimumEvaluator.

void ScXMLEvaluator::clearTemporaryVariables (void)\fC [virtual]\fP

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.
