Public Member Functions

Static Public Member Functions

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 typesystem.

Member Function Documentation

SoType ScXMLEvaluator::getClassTypeId (void) [static]

This static method returns the SoType object associated with objects of this class. See Also:

: SoBase::getClassTypeId

Reimplemented from ScXMLObject.

Reimplemented in ScXMLCoinEvaluator, ScXMLECMAScriptEvaluator, ScXMLMinimumEvaluator, and ScXMLXPathEvaluator.

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. See Also:

: SoBase::getTypeId() const

Implements ScXMLObject.

Implemented in ScXMLCoinEvaluator, ScXMLECMAScriptEvaluator, ScXMLMinimumEvaluator, and ScXMLXPathEvaluator.

void ScXMLEvaluator::initClass (void) [static]

Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. See Also:

: SoBase::initClass()

Reimplemented from ScXMLObject.

Reimplemented in ScXMLCoinEvaluator, ScXMLECMAScriptEvaluator, ScXMLMinimumEvaluator, and ScXMLXPathEvaluator.

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.
