Method Detail

getSyntaxList

public java.util.List getSyntaxList()

Description copied from class: ItemHandler

Returns a list of patterns representing the item pattern syntaxes this handler can process, or null if no particular syntax is required. Note that this information is not automatically used when determining whether this handler should add actions to an agenda item. Instead, this handler's contribution to that decision is supplied by the ItemHandler.appliesTo(AgendaItem) method.

Overrides:

getSyntaxList in class ItemHandler

See Also:

AgendaItem.getPattern()

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

handle

public void handle(AgendaItem item)

Description copied from class: ItemHandler

Called to perform the action implemented by this handler, if the selected HandlerAction so desires.

Overrides:

handle in class ItemHandler
