java.lang.Object
  cz.cuni.amis.pogamut.base.communication.worldview.object.WorldObjectId

All Implemented Interfaces:

Serializable

public class WorldObjectId
extends Object
implements Serializable

Interface that is returning an unique id of the world object. The id must be unique among all the objects in the world.

Every implementations MUST implement equals() and hashCode() correctly as we will use this inside hashmaps/sets.
