Class ImmutableHashableObjectFactory

java.lang.Object

burlap.oomdp.statehashing.ImmutableHashableObjectFactory

All Implemented Interfaces:

HashableObjectFactory

public class ImmutableHashableObjectFactory
extends java.lang.Object
implements HashableObjectFactory

This is a HashingFactory specifically for ImmutableObjects. By caching hashes with ObjectInstances themselves, reusing ImmutableObjectInstances between states, allows for reduced needs for caching.
