ByteCodeClassLoader(java.lang.ClassLoader oParentClassLoader)
Creates a class loader that delegates to the specified parent class loader

Method Summary

void	addClassDef(java.lang.String sClassName, byte[] ayClassByteCode) Add a class defined by its byte code to this loader.
protected java.lang.Class	findClass(java.lang.String sClassName) Override the default implementation of the standard findClass() method to load in our classes defined via addClassDef()
