Member Function Documentation

copyMatchInfo()

virtual SoElement * SoGLShaderProgramElement::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.

Reimplemented from SoReplacedElement.

init()

virtual void SoGLShaderProgramElement::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 SoReplacedElement.

matches()

virtual SbBool SoGLShaderProgramElement::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.

Reimplemented from SoReplacedElement.

pop()

virtual void SoGLShaderProgramElement::pop ( SoState * state, const SoElement * prevTopElement )

virtual

This method is called when the state is popped, and the depth of the element is bigger than the current state depth. pop() is called on the new top of stack, and a pointer to the previous top of stack is passed in prevTopElement.

Override this method if you need to copy some state information from the previous top of stack.

Reimplemented from SoElement.

push()

virtual void SoGLShaderProgramElement::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.
