public java.util.List getSyntaxList()

ItemHandler.appliesTo(AgendaItem)
method.

public boolean appliesTo(AgendaItem item)

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.
