Class EventBusAdapter

java.lang.Object
  com.google.web.bindery.event.shared.EventBus
      com.ekuefler.supereventbus.EventBusAdapter

public class EventBusAdapter
extends EventBus

An adapter allowing SuperEventBus to be referenced via GWT's built-in EventBus interface. Calls to methods on this class are forwarded to an underlying EventBus, effectively allowing an EventBus to be passed to existing methods that expect a legacy EventBus. Since only a small subset of EventBus's functionality is exposed here, this should only be used for existing/legacy code that can't be refactored to use EventBus directly.
