public interface AbstractObjectParameterizedGroundedAction
extends AbstractGroundedAction

An interface extension to the AbstractGroundedAction interface for grounded actions whose parameter included references to OO-MDP ObjectInstances. This is a special interface because grounded actions that have parameters references to OO-MDO ObjectInstances may require special care by a planning or learning algorithm since the names of object references can change between states that are otherwise equal (that is, states that are object identifier independent).

This interface also includes the inner class AbstractObjectParameterizedGroundedAction.Helper which provides the static method AbstractObjectParameterizedGroundedAction.Helper.translateParameters(AbstractGroundedAction, burlap.oomdp.core.states.State, burlap.oomdp.core.states.State) that can be used to reparameterize a AbstractObjectParameterizedGroundedAction's object references to equivalent ObjectInstance objects in separate state with different names. See its method documentation for more information.
