Field Detail

action

public Action action

The action object for this grounded action

Constructor Detail

GroundedAction

public GroundedAction(Action a,
              java.lang.String[] p)

Initializes the GroundedAction with the given Action reference and action parameters.

Parameters:

a - the action reference

p - a String array of object parameters for the action

GroundedAction

public GroundedAction(Action a,
              java.lang.String p)

Initializes the GroundedAction with the given Action reference and action parameters.

Parameters:

a - the action reference

p - a comma delineated String representing the object parameters for the action.

Method Detail

executeIn

public State executeIn(State s)

Executes the grounded action on a given state

Specified by:

executeIn in class AbstractGroundedAction

Parameters:

s - the state on which to execute the action

Returns:

The state after the action has been executed

actionName

public java.lang.String actionName()

Returns the action name for this grounded action.

Specified by:

actionName in class AbstractGroundedAction

Returns:

the action name for this grounded action.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object other)

Overrides:

equals in class java.lang.Object

isExecutable

public boolean isExecutable()

Description copied from class: AbstractGroundedAction

Returns true if this grounded action can be directly executed on a state with the AbstractGroundedAction.executeIn(State) method. For example, a single agent domain grounded action is executable; a stochastic games single grounded action is not, because the action of all other agents must also be known in order to get the next state.

Specified by:

isExecutable in class AbstractGroundedAction

Returns:

true if this grounded action can be directly executed on a state; false otherwise.

actionDomainIsObjectIdentifierDependent

public boolean actionDomainIsObjectIdentifierDependent()

Description copied from class: AbstractGroundedAction

Returns true if the domain to which this action belongs is object identifier dependent

Specified by:

actionDomainIsObjectIdentifierDependent in class AbstractGroundedAction

Returns:

true if the domain to which this action belongs is object identifier dependent; false otherwise

copy

public AbstractGroundedAction copy()

Description copied from class: AbstractGroundedAction

Returns a copy of this grounded action.

Specified by:

copy in class AbstractGroundedAction

Returns:

a copy of this grounded action.

parametersAreObjects

public boolean parametersAreObjects()

Description copied from class: AbstractGroundedAction

Returns true if all parameters (if any) for this action represent OO-MDP objects in a state; false otherwise. This method will query the refenced action object to evaluate. (e.g., GroundedAction will query its referenced Action object; GroundedSingleAction will query its referenced SingleAction.

Specified by:

parametersAreObjects in class AbstractGroundedAction

Returns:

true if all parameters (if any) for this action represent OO-MDP objects in a state; false otherwise.
