Destructor.

Member Function Documentation

getClassTypeId()

SoType SoTextureOverrideElement::getClassTypeId ( void  )

static

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

getClassStackIndex()

int SoTextureOverrideElement::getClassStackIndex ( void  )

static

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

createInstance()

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.

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

initClass()

void SoTextureOverrideElement::initClass ( void  )

static

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

matches()

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.

copyMatchInfo()

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 scene graph traversal caching operations.

Implements SoElement.

init()

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.

push()

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.

print()

void SoTextureOverrideElement::print ( FILE *  file ) const

virtual

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

Reimplemented from SoElement.
