## Detailed Description

The **SoTextureCombineElement** class is yet to be documented.

FIXME: write doc.

Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.\

**Since**

Coin 2.3

## Constructor & Destructor Documentation

### SoTextureCombineElement::~SoTextureCombineElement () \[protected\], \[virtual\]

Destructor.

## Member Function Documentation

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

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

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

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

### void \* SoTextureCombineElement::createInstance (void ) \[static\]

*This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.*\

 Creates a new instance of the class type corresponding to the **SoType** object.

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

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

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

This function initializes the element type in the given **SoState**. It is called for the first element of each enabled element type in **SoState** objects.

Reimplemented from **SoElement**.

### void SoTextureCombineElement::push (SoState \* state) \[virtual\]

This method is called every time a new element is required in one of the stacks. This happens when a writable element is requested, using **SoState::getElement()** or indirectly **SoElement::getElement()**, and the depth of the current element is less than the state depth.

Override this method if your element needs to copy data from the previous top of stack. The **push()** method is called on the new element, and the previous element can be found using **SoElement::getNextInStack()**.

Reimplemented from **SoElement**.

### SbBool SoTextureCombineElement::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 \* SoTextureCombineElement::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**.
