Class ActionTransitions

java.lang.Object

burlap.behavior.singleagent.planning.stochastic.ActionTransitions

public class ActionTransitions
extends java.lang.Object

This class is used as a wrapper for specifying the possible state transitions that can occur when an action is applied from a particular state (which is kept hidden). The transition dynamics stores state-hashed transition dynamics. This class can be useful to planners like tabular VI that need to work with transition dynamics of the domain.

ActionTransitions

public ActionTransitions(GroundedAction ga,
                 java.util.List<TransitionProbability> transitions,
                 HashableStateFactory hashingFactory)

Constructs the the ActionTransitions from the GroundedAction that generated the transitions and the set of transition probabilities.

Parameters:

ga - the GroundedAction that generated the possible transitions

transitions - the transition probabilities

hashingFactory - a hashingFactory that can be used to hash the states in the TransitionProbability data structure.

ActionTransitions

public ActionTransitions(State s,
                 GroundedAction ga,
                 HashableStateFactory hashingFactory)

Constructs the the ActionTransitions from a source state, and an action to apply in that source state.

Parameters:

s - the state from which to generate the hashed transitions

ga - the GroundedAction to be applied in the source state

hashingFactory - a hashingFactory that can be used to hash the states in the TransitionProbability data structures that are returned from applying ga in s.

Method Detail

matchingTransitions

public boolean matchingTransitions(GroundedAction oga)

Returns whether these action transitions are for the specified GroundedAction

Parameters:

oga - the GroundedAction to check against

Returns:

true if this object's transition probabilities were generated with GroundedAction oga; false otherwise.
