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​.

---

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​.

---

virtual void SoGLShaderProgramElement::pop (SoState * state, const SoElement * prevTopElement) [virtual]This method is callled 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​.

---

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​.

---

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 scenegraph traversal caching operations​. Reimplemented from SoReplacedElement​.
