Inheritance diagram for SoAccumulatedElement:

SoElement List of all members.

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

SoType SoAccumulatedElement::getClassTypeId ( void   )  [static]

This static method returns the class type.

Reimplemented from SoElement.

int SoAccumulatedElement::getClassStackIndex ( void   )  [static]

This static method returns the state stack index for the class.

Reimplemented from SoElement.

void SoAccumulatedElement::initClass ( void   )  [static]

Initialize relevant common data for all instances, like the type system.

Reimplemented from SoElement.

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.
