Detailed Description

The SoTextureOverrideElement makes it possible to override texture elements.

Constructor & Destructor Documentation

SoTextureOverrideElement::~SoTextureOverrideElement (void) [protected], [virtual]

The destructor.

Member Function Documentation

void * SoTextureOverrideElement::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.

void SoTextureOverrideElement::initClass (void) [static]

This static method initializes static data for the SoTextureOverrideElement class.

SbBool SoTextureOverrideElement::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 * SoTextureOverrideElement::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 scenegraph traversal caching operations.

Implements SoElement.

void SoTextureOverrideElement::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 SoTextureOverrideElement::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.

void SoTextureOverrideElement::print (FILE * file) const [virtual]

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

Reimplemented from SoElement.
