public JointAction()

JointAction

public JointAction(java.util.List<Action> actions)

Adds all Action objects in a list to this joint action.

Parameters:

Returns the number of actions in this joint action.

Returns:

the number of actions in this joint action.

getActions

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

Returns a list of the actions in this joint action. Modifying the returned list does not modify the structure of this joint action.

Returns:

a list of the actions in this joint action

setActions

public void setActions(java.util.List<Action> actions)

setAction

public void setAction(int agentNum,
                      Action a)

Sets the action for the specified agent. If the internal joint action does not have space for an agent with that number, the joint action size will be expanded with null entries until there is space.

Parameters:

agentNum - the agent whose action is being set

a - the action of the agent

action

public Action action(int agentNum)

Returns the action taken by the agent

Parameters:

agentNum - the agent whose action is being queried
