Constructor Detail

GraphDefinedDomain.GraphAction

public GraphDefinedDomain.GraphAction(Domain domain,
                              int aId,
                              java.util.Map<java.lang.Integer,java.util.Map<java.lang.Integer,java.util.Set<GraphDefinedDomain.NodeTransitionProbability>>> transitionDynamics)

Initializes a graph action object for the given domain and for the action of the given number. The name of this action will be the constant BASEACTIONNAMEi where i is the action number specified.

Parameters:

domain - the domain of the action

aId - the action identifier number

Method Detail

applicableInState

public boolean applicableInState(State st,
                        GroundedAction groundedAction)

Description copied from class: Action

Returns true if this action can be applied in this specified state with the parameters specified by the provided GroundedAction Default behavior is that an action can be applied in any state, but this will need be overridden if that is not the case.

Overrides:

applicableInState in class SimpleAction

Parameters:

st - the state to perform the action on

groundedAction - the GroundedAction specifying the parameters to use

Returns:

whether this action can be performed on the given state with the given parameters

performActionHelper

protected State performActionHelper(State st,
                        GroundedAction groundedAction)

Description copied from class: Action

This method determines what happens when an action is applied in the given state with the given parameters. The State object s may be directly modified in this method since the parent method (Action.performAction(burlap.oomdp.core.states.State, GroundedAction) first copies the input state to pass to this helper method. The resulting state (which may be s) should then be returned.

Specified by:

performActionHelper in class Action

Parameters:

st - the state to perform the action on

groundedAction - the GroundedAction specifying the parameters to use

Returns:

the resulting State from performing this action

getTransitions

public java.util.List<TransitionProbability> getTransitions(State st,
                                                   GroundedAction groundedAction)

Description copied from interface: FullActionModel

Returns the transition probabilities for applying this action in the given state with the given set of parameters. Transition probabilities are specified as list of TransitionProbability objects. The list is only required to contain transitions with non-zero probability.

Specified by:

getTransitions in interface FullActionModel

Parameters:

st - the state from which the transition probabilities when applying this action will be returned.

groundedAction - the GroundedAction specifying the parameters to use

Returns:

a List of transition probabilities for applying this action in the given state with the given set of parameters

getTransitionDynamics

public java.util.Map<java.lang.Integer,java.util.Map<java.lang.Integer,java.util.Set<GraphDefinedDomain.NodeTransitionProbability>>> getTransitionDynamics()

setTransitionDynamics

public void setTransitionDynamics(java.util.Map<java.lang.Integer,java.util.Map<java.lang.Integer,java.util.Set<GraphDefinedDomain.NodeTransitionProbability>>> transitionDynamics)
