Method Detail

appliesTo

public boolean appliesTo(AgendaItem item)
Description copied from class: ItemHandler
Gives this handler a say in whether it should add actions to an item. If this method returns false for an AgendaItem, or the item's wantsActionsFrom method returns false for this handler, this handler will not be asked to add actions to that item.

Overrides:
appliesTo in class ItemHandler
See Also:
AgendaItem.wantsActionsFrom(ItemHandler handler)

addHandlerActions

public void addHandlerActions(AgendaItem item)
Description copied from class: ItemHandler
Called to add any HandlerActions 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.

Overrides:
addHandlerActions in class ItemHandler

reviseHandlerActions

public void reviseHandlerActions(AgendaItem item,
                                 java.lang.Object reason)
Description copied from class: ItemHandler
Called after something has happened that may require new HandlerActions to be added to an item. Typically, this method is called as a consequnce of an ItemHandler -- usually this ItemHandler -- calling the controller's reconsiderHandler method. In other words, the usual case is when an ItemHandler causes its own reviseHandlerActions method to be called; and consequencetly the handler may be able to agree with itself (so to speak) about what various "reason" objects mean.

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.

Overrides:
reviseHandlerActions in class ItemHandler
