Class HashableState.CachedHashableState

java.lang.Object

burlap.oomdp.statehashing.HashableState

burlap.oomdp.statehashing.HashableState.CachedHashableState

All Implemented Interfaces:

State

Direct Known Subclasses:

SimpleHashableStateFactory.SimpleCachedHashableState

Enclosing class:

HashableState

public abstract static class HashableState.CachedHashableState
extends HashableState

A hash code cached abstract implementation of HashableState. Once a hash code is computed, it is saved so that it does not need to be used again. Implementing this class only requires implementing computeHashCode().
