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. See also SoReplacedElement, SoFloatElement, SoInt32Element Constructor & Destructor Documentation SoAccumulatedElement::~SoAccumulatedElement (void) [protected], [virtual] Destructor. Member Function Documentation SoType SoAccumulatedElement::getClassTypeId (void) [static] This static method returns the SoType object associated with objects of this class. int SoAccumulatedElement::getClassStackIndex (void) [static] This static method returns the state stack index for the class. void SoAccumulatedElement::initClass (void) [static] Initialize relevant common data for all instances, like the type system. SbBool SoAccumulatedElement::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. Implements SoElement. Reimplemented in SoModelMatrixElement. void SoAccumulatedElement::init (SoState * state) [protected], [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 SoElement. Reimplemented in SoBBoxModelMatrixElement, SoBumpMapMatrixElement, SoClipPlaneElement, SoGLClipPlaneElement, SoGLModelMatrixElement, SoGLMultiTextureMatrixElement, SoGLVertexAttributeElement, SoLightElement, SoModelMatrixElement, SoMultiTextureMatrixElement, SoProfileElement, and SoVertexAttributeElement. void SoAccumulatedElement::push (SoState * state) [protected], [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. Reimplemented in SoBBoxModelMatrixElement, SoBumpMapMatrixElement, SoClipPlaneElement, SoGLModelMatrixElement, SoGLMultiTextureMatrixElement, SoLightElement, SoModelMatrixElement, SoMultiTextureMatrixElement, SoProfileElement, and SoVertexAttributeElement. 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 scene graph 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.
