Class ChainEventHandler<Event>

java.lang.Object

org.whaka.mock.ChainEventHandler<Event>

All Implemented Interfaces:

java.util.function.Predicate<Event>, EventCollector.EventHandler<Event>

public class ChainEventHandler<Event>
extends java.lang.Object
implements EventCollector.EventHandler<Event>

Implementation of the StreamHandler that chains registered delegates so that next filter is called only if previous one returned true.

Since this class implements EventCollector.EventHandler - registered handlers will receive call to the eventCollected(Object) method when this handler gets the call.

eventCollected

public void eventCollected(Event event)

Description copied from interface: EventCollector.EventHandler

This method is called by an EventCollector when new captured event has passed ALL filters and already got collected. So if this instance for an event X returns false from the Predicate.test(Object) method - then EventCollector.EventHandler.eventCollected(Object) definitely will NOT be called for the event X. But if this instance for an event X returns true from the Predicate.test(Object) method - then EventCollector.EventHandler.eventCollected(Object) might be called; but only if all the other filters registered in the same collector will also return true.
