Inheritance diagram for ScXMLEvaluator:

## Public Member Functions

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 void | setStateMachine (ScXMLStateMachine *sm)
ScXMLStateMachine * | getStateMachine (void) const
virtual ScXMLDataObj * | evaluate (const char *expression) const =0
virtual SbBool | setAtLocation (const char *location, ScXMLDataObj *obj)=0
virtual ScXMLDataObj * | locate (const char *location) const =0
virtual void | clearTemporaryVariables (void)
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 SoType | getClassTypeId (void)
static void | initClass (void)
static void | cleanClass (void)
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.

## Additional Inherited Members

Static Protected Member Functions inherited from ScXMLObject
static void | registerClassType (const char *xmlns, const char *classname, SoType type)
static void | registerInvokeClassType (const char *xmlns, const char *targettype, const char *source, SoType type)

## Member Function Documentation

## 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.

## setStateMachine()

void ScXMLEvaluator::setStateMachine | ( | ScXMLStateMachine * | sm | ) |

virtual

Override to perform actions when installed on a state machine.

Reimplemented in ScXMLCoinEvaluator, and ScXMLMinimumEvaluator.

## evaluate()

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

pure virtual

Implemented in ScXMLMinimumEvaluator.

## setAtLocation()

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

pure virtual

Implemented in ScXMLMinimumEvaluator.

## locate()

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

pure virtual

Implemented in ScXMLMinimumEvaluator.

## 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.
