def
onAnyEvent(handler: Function[Event, State]): EventHandler[State, Event]
Match any event.
Match any event.
Use this when then
State
is not needed in thehandler
, otherwise there is an overloaded method that pass the state in aBiFunction
.Note: event handlers are selected in the order they are added. Once a matching is found, it's selected for handling the event and no further lookup is done. Therefore you must make sure that their matching conditions don't overlap, otherwise you risk to 'shadow' part of your event handlers.
Extra care should be taken when using onAnyEvent as it will match any event. This method builds and returns the event handler since this will not let through any states to subsequent match statements.
- returns
An EventHandler from the appended states.
