Subj : Rhino question: multiple constructors in scriptable objects

Hi,

Is it possible to define a subclass of ScriptableObject that contains
multiple constructors (jsConstructor() methods).

I want to define a class called "ByteBuffer" extending the Scriptable
Object and instantiate it in JavaScript using different constructors.


Example Class:

public class ByteBuffer extends ScriptableObject {

    public ByteBuffer() {
    }

    public void jsConstructor() {
    }

    public void jsConstructor(String value, int encoding) {
    }

    public void jsConstructor(ByteString source) {
    }

    public String getClassName() {
        return "ByteBuffer";
    }

}

The 'ByteString' object (see example above) is also a subclass of
ScriptableObject.


I know that it's not allowed to define multiple methods called
'jsConstructor'. My question is how can I define a Host-Object which I can
instantiate it in JavaScript with different constructor signatures?

i.e.

var obj1 = new ByteBuffer();
var obj2 = new ByteBuffer("a string", 2);
var obj3 = new ByteBuffer(new ByteString("another string", 2));



Thanks,
Ishak Mesut
