Inheritance diagram for SoAccumulatedElement:
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.

This static method returns the class type. Reimplemented from SoElement. |
|
This static method returns the state stack index for the class. Reimplemented from SoElement. |
|
Initialize relevant common data for all instances, like the type system. Reimplemented from SoElement. |
|
This function returns If the application programmer's extension element has a matches() function, it should also have a copyMatchInfo() function. Implements SoElement. |
|
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. |
|
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. |
|
Empty the list of node ids. |
|
Add the node id of node to the list of node ids. |
|
Empty the list of node ids, and add the id of node. |
|
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. |
|
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. |
|
Adds the element to the cache. Reimplemented from SoElement. |
|
Stores the internal list of node id values for nodes accumulated on the stack for the element. |
