## Detailed Description

The **SoInt32Element** class is the base class for elements that simply store a 32-bit integer.

This is the superclass of elements where the new element data *replaces* the old data, and where the data the element stores is a simple 32-bit integer value.

This element is like a convenient light-weight version of the **SoReplacedElement**. It differs from the **SoReplacedElement** in that the **set()** and **get()** methods are already implemented, since it is known that subclasses will still contain just a single 32-bit integer value.

**SoReplacedElement**, **SoFloatElement**, **SoAccumulatedElement**

## Constructor & Destructor Documentation

### SoInt32Element::~SoInt32Element (void ) \[protected\], \[virtual\]

Destructor.

## Member Function Documentation

### SoType SoInt32Element::getClassTypeId (void ) \[static\]

This static method returns the **SoType** object associated with objects of this class.

### int SoInt32Element::getClassStackIndex (void ) \[static\]

This static method returns the state stack index for the class.

### void SoInt32Element::initClass (void ) \[static\]

Initialize relevant common data for all instances, like the type system.

### void SoInt32Element::init (SoState \* state) \[virtual\]

Initializes the element to its default value. The default value for the int32 value is 0.

Reimplemented from **SoElement**.

Reimplemented in **SoAnnoText3CharOrientElement**, **SoAnnoText3FontSizeHintElement**, **SoAnnoText3RenderPrintElement**, **SoComplexityTypeElement**, **SoDecimationTypeElement**, **SoDrawStyleElement**, **SoGLDrawStyleElement**, **SoGLLightIdElement**, **SoGLLinePatternElement**, **SoGLShadowCullingElement**, **SoLightModelElement**, **SoLinePatternElement**, **SoMaterialBindingElement**, **SoNormalBindingElement**, **SoPickStyleElement**, **SoShadowStyleElement**, **SoSwitchElement**, **SoTextOutlineEnabledElement**, **SoTextureCoordinateBindingElement**, **SoTextureUnitElement**, **SoUnitsElement**, and **SoVertexAttributeBindingElement**.

### SbBool SoInt32Element::matches (const SoElement \* element) const \[virtual\]

This function returns TRUE is the element matches another element (of the same class), with respect to cache validity.

If the application programmer's extension element has a **matches()** function, it should also have a **copyMatchInfo()** function.

Implements **SoElement**.

### SoElement \* SoInt32Element::copyMatchInfo (void ) const \[virtual\]

This function creates a copy of the element that contains enough information to enable the **matches()** function to work.

Used to help with scene graph traversal caching operations.

Implements **SoElement**.

### void SoInt32Element::print (FILE \* file) const \[virtual\]

This function is for printing element information, and is used mostly for debugging purposes.

Reimplemented from **SoElement**.

### void SoInt32Element::set (const int index, SoState \*const state, SoNode \*const node, const int32\_t value) \[static\]

Static method for setting the *value* of an element in the given *state* at the given stack *index*.

### void SoInt32Element::set (const int index, SoState \*const state, const int32\_t value) \[static\]

Static method for setting the *value* of an element in the given *state* at the given *stackIndex*.

### int32\_t SoInt32Element::get (const int index, SoState \*const state) \[static\]

Static method to fetch the value of the element of this type from the given *state* at the given stack *index*.

### void SoInt32Element::setElt (int32\_t value) \[virtual\]

Set element value.

Reimplemented in **SoGLDrawStyleElement**, **SoGLLinePatternElement**, and **SoGLShadowCullingElement**.

## Member Data Documentation

### int32\_t SoInt32Element::data \[protected\]

The 32-bit integer value of the element.
