Class EventBusManager

java.lang.Object

org.zimowski.bambi.editor.studio.eventbus.EventBusManager

public class EventBusManager
extends Object

Centralized manager for Guaava EventBus which by default is context unaware. This manager defines the context as a top level window from which events originate. Each window's Object.hashCode() is used as context bus number, therefore guaranteeing every window will have its own event bus. It is critical that all EventBus requests originate with this manager if context management is required. Top level windows should register with the manager first by letting it know immedialy after they are constructed (setWindowInstantiated(MainWindow) - best called from inside the constructor, then each time when window gains focus manager must be told so via switchContext(MainWindow). Also all subscribers, rather than registering directly with the bus, must register with this manager instead, via registerWithBus(Object).
