close()

Close the context: clear observers, stop notifications, and remove event listeners from its parent context.

isSubscribed(observer)

Check if an observer is subscribed to this context

notifyObservers(event, observers)

protected

Publish an event to the registered observers. Please note the notification is queued and performed asynchronously so that we allow fluent APIs such as ctx.bind('key').to(...).tag(...); and give observers the fully populated binding.

subscribe(observer)

Add a context event observer to the context

unsubscribe(observer)

Remove the context event observer from the context

waitUntilPendingNotificationsDone(timeout)

Wait until observers are notified for all of currently pending notification events.

This method is for test only to perform assertions after observers are notified for relevant events.
