Member Function Documentation
   SoType SoGLDepthBufferElement::getClassTypeId (void ) [static]
       This static method returns the SoType object associated with objects of
       this class.

   int SoGLDepthBufferElement::getClassStackIndex (void ) [static]
       This static method returns the state stack index for the class.

   void * SoGLDepthBufferElement::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 SoGLDepthBufferElement::initClass (void ) [static]
       Initialize relevant common data for all instances, like the type
       system.

   void SoGLDepthBufferElement::init (SoState * state) [virtual]
       Internal Coin method.

       Reimplemented from SoDepthBufferElement.

   void SoGLDepthBufferElement::push (SoState * state) [virtual]
       Internal Coin method.

       Reimplemented from SoDepthBufferElement.

   void SoGLDepthBufferElement::pop (SoState * state, const SoElement *
       prevTopElement) [virtual]
       Internal Coin method.

       Reimplemented from SoDepthBufferElement.

   void SoGLDepthBufferElement::setElt (SbBool test, SbBool write,
       DepthWriteFunction function, SbVec2f range) [protected],  [virtual]
       Set this element's values.

       Reimplemented from SoDepthBufferElement.
