# ScXMLConstantDataObj(3)

base class for immediate data values

## NAME

ScXMLConstantDataObj - base class for immediate data values

## SYNOPSIS

\#include \<Inventor/scxmlScXMLEvaluator.h\>

Inherits **ScXMLDataObj**.

Inherited by **ScXMLBoolDataObj**, **ScXMLRealDataObj**, **ScXMLSbDataObj**, and **ScXMLStringDataObj**.

### 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 **ScXMLDataObj** \* **clone** (void) const =0\
 virtual void **convertToString** (**SbString** &str) const =0\

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.

### 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 ScXMLConstantDataObj::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.

**SoBase::getTypeId() const**

Implements **ScXMLDataObj**.

Implemented in **ScXMLBoolDataObj**, **ScXMLRealDataObj**, **ScXMLSbDataObj**, and **ScXMLStringDataObj**.
