Constructor Detail

ComponentActionList

public ComponentActionList(IEnvironmentSpace space)

Create a new action list.

Method Detail

scheduleComponentAction

public int scheduleComponentAction(ISpaceAction action,
                                   java.util.Map parameters,
                                   IResultListener listener)

Schedules an component action.

Parameters:

action - The action.

parameters - parameters for the action (may be null)

listener - the result listener

cancelComponentAction

public void cancelComponentAction(int id)

Cancels a component action.

addComponentAction

public void addComponentAction(ComponentActionList.ActionEntry entry)

Add an component action.

Parameters:

entry - The action entry.

removeComponentAction

public void removeComponentAction(ComponentActionList.ActionEntry entry)

Remove an component action.

Parameters:

entry - The action entry.

getActionEntries

public ComponentActionList.ActionEntry[] getActionEntries()

Get the queued entries, which have not yet been executed.

setOrdering

public void setOrdering(java.util.Comparator comp)

Set an ordering used for executing actions.

Parameters:

comp - The comparator representing the ordering.

executeActions

public void executeActions(IFilter filter,
                           boolean wakeup)

Should be called on environment thread only.

Parameters:

filter - A filter to select only a subset of actions (or null for all actions).

wakeup - Immediately wake up each calling component after its action has been executed (otherwise wakeupComponents() has to be called separately).

wakeupComponents

public void wakeupComponents(IFilter filter)

Should be called on environment thread only.

Parameters:

filter - A filter to select only a subset of actions (or null for all actions). (otherwise wakeupComponents() has to be called separately).

setScheduleCommand

public void setScheduleCommand(ICommand cmd)

Set the schedule command to be invoked, when an action should be scheduled. Per default, an action is added to the list, but custom commands might decide to execute action immediately or alter the list in arbitrary ways. The command parameter is of type ActionEntry.
