Constructor Detail

BlockDude.MoveAction

public BlockDude.MoveAction(java.lang.String name,
                    Domain domain,
                    int dir)

Initializes.

Parameters:

name - the name of the action

domain - the domain to which it will be associated

dir - the direction of movement: +1 for east; -1 for west.

Method Detail

performAction

public State performAction(State s,
                  java.lang.String[] params)

Description copied from class: Action

Performs this action in the specified state using the specified parameters and returns the resulting state. The input state will not be modified with a deep copied state returned instead (unless this method is overriden, which may result in a semi-deep copy). If the action is not applicable in state s with parameters params, then a copy of the input state is returned. In general Action subclasses should *NOT* override this method and should instead override the abstract Action.performActionHelper(State, String[]) method. Only override this method if you are seeking to perform memory optimization with semi-shallow copies of states and know what you're doing.

Overrides:

performAction in class Action

Parameters:

s - the state in which the action is to be performed.

params - a String array specifying the action object parameters

Returns:

the state that resulted from applying this action

performActionHelper

protected State performActionHelper(State s,
                        java.lang.String[] params)

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 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:

s - the state to perform the action on

params - a String array specifying the action object parameters

Returns:

the resulting State from performing this action

getTransitions

public java.util.List<TransitionProbability> getTransitions(State s,
                                                   java.lang.String[] params)

Description copied from class: Action

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. Since not all planning algorithms require the full transition dynamics (and since it's impossible to enumerate them in some infinite state space domains), this method is not requried to be implemented. However, it will throw an UnsupportedOperationException if it is not overriden by the Action subclass if it is called by an algorithm that requires it.

Overrides:

getTransitions in class Action

Parameters:

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

params - a String array specifying the action object parameters

Returns:

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