# ScXMLCoinEvaluator(3)

implements the evaluator for the custom profile named "x-coin".

## NAME

ScXMLCoinEvaluator - implements the evaluator for the custom profile named "x-coin".

## SYNOPSIS

\#include \<Inventor/scxml/ScXMLCoinEvaluator.h\>

Inherits **ScXMLEvaluator**.

### Public Member Functions

virtual **SoType** **getTypeId** (void) const\
 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)\
 virtual **ScXMLDataObj** \* **evaluate** (const char \*expression) const\
 virtual SbBool **setAtLocation** (const char \*location, **ScXMLDataObj** \*obj)\
 virtual **ScXMLDataObj** \* **locate** (const char \*location) const\
 virtual void **clearTemporaryVariables** (void)\
 void **dumpTemporaries** (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 \* **createInstance** (void)\
 static void **initClass** (void)\
 static void **cleanClass** (void)\

Static Public Member Functions inherited from **ScXMLEvaluator** 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)\

## Detailed Description

implements the evaluator for the custom profile named "x-coin".

The x-coin profile extends over the minimum profile with data interpretation, logical operators, arithmetic expressions, and some convenience data model features like access to the scene graph and temporary storage of variables.
