Java Events im Vergleich zu C# Events

Ich mache hier mal ein Vergleich um zu zeigen, was ich mit unnötige Komplexität und Unübersichtlichkeit meine.

Erstellen von Custom Events

Java

Java
1 23 45	public interface EventCustom extends EventListener     {        public void fireEvent(EventObject e);     }
GeSHi 1.0.8.8

Java
1 23 45 67 89 1011 1213 1415 1617 18	protected Vector<EventCustom> listenerList = new Vector<EventCustom>();      public void addEventListener(EventCustom eventListener)     {        listenerList.add(eventListener);     }      public void removeEventListener(EventCustom eventListener)    {         listenerList.remove(eventListener);    }         private void fireEndOfGame(EventObject e)     {        for(EventCustom listener: listenerList)             listener.fireEvent(e);    }
GeSHi 1.0.8.8

C#

C#
1	public delegate void EventCustomHandler(object sender);
GeSHi 1.0.8.8

C#
1	private EventCustomHandler CustomEvent;
GeSHi 1.0.8.8

Event aufrufen

Java

Java
1	fireEndOfGame(new EventObject(this));
GeSHi 1.0.8.8

C#

C#
1	if(CustomEvent!=null) CustomEvent(this);
GeSHi 1.0.8.8

Listener hinzufügen

Java

Java
1 23 45 67 89	anyObject.addEventListener(new EventCustom() {    @Override     public void fireEvent(EventObject e)    {          // Bla bla bla    } });
GeSHi 1.0.8.8

oder

Java
1 23 45 67 89	private EventCustom eventCustom = new EventCustom()     {        @Override         public void fireEvent(EventObject e)        {             // bla bla bla        }     };
GeSHi 1.0.8.8

Java
1	anyObject.addEventListener(eventCustom);
GeSHi 1.0.8.8

oder

Java
1 23 45 67 89 1011 1213 1415	public class CustomEvent implements EventCustom {    private Object sender;             public CustomEvent(Object sender)     {        this.sender = sender;     }            @Override    public void fireEvent(EventObject e)     {        // bla bla bla     }}
GeSHi 1.0.8.8

Java
1	private CustomEvent customEvent = new CustomEvent(this);
GeSHi 1.0.8.8

Java
1	anyObject.addEventListener(eventCustom);
GeSHi 1.0.8.8

 

C#

C#
1	anyObject.CustomEvent += AnyObject_CustomEvent;
GeSHi 1.0.8.8

C#
1 23 4	private void AnyObject_CustomEvent(object sender) {     // bla bla bla }
GeSHi 1.0.8.8

oder

C#
1 23 4	this.CustomEvent += delegate(object sender) {    // bla bla bla };
GeSHi 1.0.8.8

 

So… Genug für heute….
