public interface OOState
extends State

This interface provides common methods for working with states that are represented with the the OO-MDP paradigm in which states are a collection of objects. Each object itself implements ObjectInstance and is an implementation of State, but otherwise is just a java object of your own definition, which makes defining and OO-MDP object class the same procedure as defining a Java object class.
