Method Detail

isStillValid

public boolean isStillValid()

Description copied from class: HandlerAction

Called when something has happened that might mean this action no longer makes sense and should be deleted. The method in the HandlerAction class just returns true and is overridden in subclasses that have instances that may cease to be valid.

Typically, this method is called as a consequence of an ItemHandler calling the controllers's checkActionValidity method.

Overrides:

isStillValid in class HandlerAction

See Also:

PanelController.checkActionValidity(ItemHandler handler, Object reason)

isReady

public boolean isReady()

Description copied from class: HandlerAction

Indicates whether this action is ready to be used or else is waiting for something that would enable it to be used. The method in the HandlerAction class just returns true and is overridden in subclasses that have instances that are not always ready.

Overrides:

isReady in class HandlerAction

See Also:

HandlerAction.getUnreadyReason()

computeStatus

public void computeStatus()

Description copied from class: HandlerAction

Called when something has happened that might have changed this action's ready status. The method in the HandlerAction class does nothing and is overridden in subclasses that have instances that are not always ready.

Overrides:

computeStatus in class HandlerAction

getUnreadyReason

public ActionUnreadyReason getUnreadyReason()

Description copied from class: HandlerAction

Returns an object that explains why this handler is not ready to be used.

Overrides:

getUnreadyReason in class HandlerAction

See Also:

HandlerAction.isReady()

handle

public void handle(AgendaItem item)

Description copied from class: HandlerAction

Handle the item in the manner appropriate to this handler-action. The method in the HandlerAction class merely changes the item's status to COMPLETE and is overridden in subclasses that handle the item in more interesting ways.

Overrides:

handle in class HandlerAction

setSatusAfterExpansion

protected void setSatusAfterExpansion(AgendaItem item)

do_expansion

protected void do_expansion(AgendaItem item)

getInstantiationEnv

protected MatchEnv getInstantiationEnv()

reevaluateFilters

protected void reevaluateFilters(AgendaItem item)
