Manages a list of vtkGeoTreeNodes.
vtkGeoTreeNodeCache keeps track of a linked list of vtkGeoTreeNodes, and has operations to move nodes to the front of the list and to delete data from the least used nodes. This is used to recover memory from nodes that store data that hasn't been used in a while.

void vtkGeoTreeNodeCache::SendToFront | ( | vtkGeoTreeNode * | node | ) |
Send a node to the front of the list. Perform this whenever a node is accessed, so that the most recently accessed nodes' data are not deleted.
void vtkGeoTreeNodeCache::RemoveNode | ( | vtkGeoTreeNode * | node | ) |
Remove the node from the list.
|
virtual |
The current size of the list.

Removes data from the oldest nodes and removes them from the list until the list is of size CacheSize.
|
protected |
Checks whether a node is the last of a set of siblings to be removed from the list. If so, deletes data from the node and all siblings.
