# ScXMLExprDataObj(3)

## NAME

ScXMLExprDataObj

## SYNOPSIS

Inherits **ScXMLDataObj**.

Inherited by **ScXMLAddOpExprDataObj**, **ScXMLAndOpExprDataObj**, **ScXMLAppendOpExprDataObj**, **ScXMLCoinLengthFuncExprDataObj**, **ScXMLDivideOpExprDataObj**, **ScXMLEqualsOpExprDataObj**, **ScXMLMinimumExprDataObj**, **ScXMLMultiplyOpExprDataObj**, **ScXMLNegateOpExprDataObj**, **ScXMLNotOpExprDataObj**, **ScXMLOrOpExprDataObj**, **ScXMLReferenceDataObj**, and **ScXMLSubtractOpExprDataObj**.

### 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. **ScXMLDataObj** \* **evaluate** (**ScXMLStateMachine** \*sm)\

Public Member Functions inherited from **ScXMLDataObj** void **setContainer** (**ScXMLObject** \*container)\
 **ScXMLObject** \* **getContainer** (void) const\

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 **ScXMLDataObj** 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.

### Protected Member Functions

virtual SbBool **evaluateNow** (**ScXMLStateMachine** \*sm, **ScXMLDataObj** \*&pointer) const =0\

### 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

### virtual SoType ScXMLExprDataObj::getTypeId (void ) const \[pure virtual\]
