org.apache.bcel.util
Class BCELifier  

java.lang.Object
  org.apache.bcel.classfile.EmptyVisitor
      org.apache.bcel.util.BCELifier

All Implemented Interfaces:

org.apache.bcel.classfile.Visitor

---

public class BCELifier

extends org.apache.bcel.classfile.EmptyVisitor

This class takes a given JavaClass object and converts it to a Java program that creates that very class using BCEL. This gives new users of BCEL a useful example showing how things are done with BCEL. It does not cover all features of BCEL, but tries to mimic hand-written code as close as possible.
