Hi, ObjectRenderers do not replace a Layout. They are classes that know how to
render objects of a specific class. For example:

class A { private int a; public int getA() { return a; }

private int b; public int getB() { return b; } }

public class ARenderer implements ObjectRenderer { public String doRender(Object o) { if(o == null) { return null; } else if {! (o instanceof A)) { return null; } else { A obj = (A) o; return "Sum = " + (obj.getA() + obj.getB()); } }

They are specified in a properties configuration file as follows: log4j.renderer.A = ARenderer
