Method Detail

setActionObserverForAllAction

public void setActionObserverForAllAction(ActionObserver observer)

Clears all action observers for all actions in this domain and then sets them to have the single action observer provided

Parameters:

observer - the single action observer to set all actions to use.

addActionObserverForAllAction

public void addActionObserverForAllAction(ActionObserver observer)

Adss the action observer to all actions associated with this domain. Actions added to this domain after this method is called will have to have the observer set for them independently or by a subsequent call to this method.

Parameters:

observer - the observer to set all actions to use.

clearAllActionObserversForAllActions

public void clearAllActionObserversForAllActions()

Clears all action observers for all action in this domain.

addAction

public void addAction(Action act)

Description copied from class: Domain

Add a single agent action that defines this domain. This method will throw a runtime exception if this domain is not an instance of the single agent domain (SADomain). The action will not be added if this domain already has a instance with the same name.

Specified by:

addAction in class Domain

Parameters:

act - the single agent action to add.

getActions

public java.util.List<Action> getActions()

Description copied from class: Domain

Returns a list of the single agent actions that define this domain. Modifying the returned list will not alter the list of actions that define this domain, because it returns a shallow copy. Modifying the actions in the returned list will, however, modify the actions in this domain. This method will throw a runtime exception if it is not an instance of the single agent domain (SADomain).

Specified by:

getActions in class Domain

Returns:

a list of the single agent actions that define this domain

getAction

public Action getAction(java.lang.String name)

Description copied from class: Domain

Returns the single agent action with the given name. This method will throw a runtime exception if it is not an instance of the single agent domain (SADomain).

Specified by:

getAction in class Domain

Parameters:

name - the name of the action to return

Returns:

the action with the given name or null if it does not exist.

addSGAgentAction

public void addSGAgentAction(SGAgentAction sa)

Description copied from class: Domain

Add a SGAgentAction that can be executed by an agent in the game. The set of SGAgentActions defines the set of joint actions in the stochastic domain (as the cross product). This method will throw a runtime exception if this domain is not an instance of the stochastic game domain (SGDomain). The action will not be added if this domain already has a instance with the same name.

Specified by:

addSGAgentAction in class Domain

Parameters:

sa - the SGAgentAction that can be executed by an agent in the game.

getAgentActions

public java.util.List<SGAgentAction> getAgentActions()

Description copied from class: Domain

Returns a list of the stochastic game actions that that can be taken by individual agents in this domain. Modifying the returned list will not alter the list of actions that define this domain, because it returns a shallow copy. Modifying the actions in the returned list will, however, modify the actions in this domain. This method will throw a runtime exception if it is not an instance of the stochastic game domain (SGDomain).

Specified by:

getAgentActions in class Domain

Returns:

a list of the stochastic game actions that that can be taken by individual agents in this domain

getSingleAction

public SGAgentAction getSingleAction(java.lang.String name)

Description copied from class: Domain

DEPRECATED: Use Domain.getSGAgentAction(String) instead.
Return the stochastic game action with the given name. This method will throw a runtime exception if it is not an instance of the stochastic game domain (SGDomain).

Specified by:

getSingleAction in class Domain

Parameters:

name - the name of the action to return

Returns:

the action with the given name or null if it does not exist.

getSGAgentAction

public SGAgentAction getSGAgentAction(java.lang.String name)

Description copied from class: Domain

Return the stochastic game action (SGAgentAction) with the given name. This method will throw a runtime exception if it is not an instance of the stochastic game domain (SGDomain).

Specified by:

getSGAgentAction in class Domain

Parameters:

name - the name of the action to return

Returns:

the SGAgentAction with the given name or null if it does not exist.

newInstance

protected Domain newInstance()

Description copied from class: Domain

Will return a new instance of this Domain's class (either SADomain or SGDomain)

Specified by:

newInstance in class Domain

Returns:

a new instance of this Domain's class (either SADomain or SGDomain)
