NAME

       SoAccumulatedElement -

       The SoAccumulatedElement class is an abstract class for storing
       accumulated state.

       This is the superclass of elements where new element data accumulates
       with older data.

SYNOPSIS

       #include <Inventor/elements/SoAccumulatedElement.h>

       Inherits SoElement.

       Inherited by SoBumpMapMatrixElement, SoClipPlaneElement,
       SoLightElement, SoModelMatrixElement, SoMultiTextureMatrixElement,
       SoProfileElement, SoTextureMatrixElement, and SoVertexAttributeElement.

Detailed Description

       The SoAccumulatedElement class is an abstract class for storing
       accumulated state.

       This is the superclass of elements where new element data accumulates
       with older data.

       The element stores node id values for all nodes accumulated during
       traversal for the current state. These id values are used to determine
       when to invalidate caches.

Member Function Documentation

   void SoAccumulatedElement::initClass (void) [static] Initialize relevant
       common data for all instances, like the type system.
       Reimplemented from SoElement.

       Reimplemented in SoBBoxModelMatrixElement, SoBumpMapMatrixElement,
       SoClipPlaneElement, SoGLClipPlaneElement, SoGLModelMatrixElement,
       SoGLMultiTextureMatrixElement, SoGLTextureMatrixElement,
       SoLightElement, SoModelMatrixElement, SoMultiTextureMatrixElement,
       SoProfileElement, and SoTextureMatrixElement.

   void SoAccumulatedElement::clearNodeIds (void) [protected] Empty the list
       of node ids.
   void SoAccumulatedElement::addNodeId (const SoNode *const  node)
       [protected] Add the node id of node to the list of node ids.
   void SoAccumulatedElement::setNodeId (const SoNode *const  node)
       [protected] Empty the list of node ids, and add the id of node.
   void SoAccumulatedElement::copyNodeIds (const SoAccumulatedElement *
       copyfrom) [protected] Convenience method which copies the node ids from
       copyfrom to this element.
       This function is an extension for Coin, and it is not available in the
       original SGI Open Inventor v2.1 API.

   SoElement * SoAccumulatedElement::copyMatchInfo (void) const [protected,
       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 SoAccumulatedElement::captureThis (SoState * state) const [protected,
       virtual] Adds the element to the cache.
       Reimplemented from SoElement.

Member Data Documentation

   SoAccumulatedElement::nodeIds [protected] Stores the internal list of node
       id values for nodes accumulated on the stack for the element.
