Notification Center for Java

This project provides a central event dispatch implementation, heavily inspired by NSNotificationCenter of Cocoa.

Simple usage Example

Observer

Observer o = new Observer(){
	public void receivedNotification(final Notification notification) {
		System.out.println("Received Notification: " + notification);
	}
}

/* Or with java 8:
 * Observer o = notification -> System.out.println("Received Notification: " + notification);
 */

...

DefaultNotificationCenter.instance().addObserver(o, Observee.MY_EVENT);

... (later)


DefaultNotificationCenter.instance().removeObserver(o);

Observee

String MY_EVENT = "MY_EVENT";

DefaultNotificationCenter.instance().postNotification(MY_EVENT);

Remarks

In its default implementation, it is designed thread safe and lock free.

To use it directly in your project you have to include the lombok.jar into your classpath.

If you do not want to include Project Lombok (and you considered this twice), run demlombok on the src folder and use the generated classes:

java -jar lombok.jar delombok src -d src-delomboked
