Hy,

A lot of time i include the processing Core.jar to some project to build libraries. So, Core.jar have to be include with the librarie pack to work.

It can be really usefull if processing sources will include some 'Interface' which gives oportunities to call some fonctions and work without including the Core.jar but just the CoreInterface.jar.
It will also provide a correct evolution of processing project without rebuilding contributed libraries each time!


small ex:

public Interface IPApplet{
    public void init();
    public void setup();
    public void draw();
    public void getApplet();
    ...
}

public class MyLib{
     
     IPApplet applet;

     public MyLib(IPApplet applet){
          this.applet = applet;
     }

     public void ToDo(){
          ...
          applet.draw();
     }
}

Well,

What i mean is if processing sources implements some interfaces, developers will be able to interact with processing methodes.

public class PApplet extends Applet
 implements IPApplet, PConstants, Runnable,
            MouseListener, MouseMotionListener, KeyListener, FocusListener
{


Well, what ever ! If noOne see the power of interfaces !
