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

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.
