public boolean appliesTo(AgendaItem item)
ItemHandler
appliesTo
in class ItemHandler
AgendaItem.wantsActionsFrom(ItemHandler handler)
public void addHandlerActions(AgendaItem item)
ItemHandler
HandlerAction
s that this
handler regards as appropriate for the specified AgendaItem.
This method is called only if both this handler's
ItemHandler.appliesTo(AgendaItem)
and the specified item's
AgendaItem.wantsActionsFrom(ItemHandler)
methods
return true.
The method provided by the ItemHandler class just adds
an action that calls this handler's ItemHandler.handle(AgendaItem)
method. This allows suitably simple handlers to avoid
working directly with HandlerActions.
Note that actions are added by calling an item's
AgendaItem.addAction(HandlerAction)
method.
addHandlerActions
in class ItemHandler
public void reviseHandlerActions(AgendaItem item, java.lang.Object reason)
ItemHandler
The reviseHandlerActions method is very similar to
the ItemHandler.addHandlerActions(AgendaItem)
method in
terms of its function and the applicability conditions
on when it is called. The main difference is that it
is called to look at AgendaItems that are not having
actions added for the first time and that may already
have an appropriate action, so that no new one needs
to be added.
Note that the usual way for an ItemHandler to get
HandlerActions removed is for it to call the controller's
checkActionValidity method. That results in calls to
HandlerAction.isStillValid()
methods.
