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

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
