com.ardor3d.bounding.UsageTreeController

All Implemented Interfaces:

CollisionTreeController

public class UsageTreeController
extends Object
implements CollisionTreeController

UsageTreeController defines a CollisionTreeController implementation that removes cache elements based on the frequency of usage. By default, and implementation in the CollisionTreeManager, the cache's key set will be ordered with the first element being the oldest used. Therefore, UsageTreeController simply removes elements from the cache starting at the first key and working up until the desired size is reached or we run out of elements.
