public class MarshaledClassLoader
extends java.lang.ClassLoader

Class loader used to resolve required classes during de-serialization.

It supports class lookup from an internal map with classes and their bytecodes.

It does class lookup through a given class loader and if the class is not found, it will look into supplied map of classes.

The map contains the class name as key and class bytecode (byte[]) as value. created on Aug 2, 2005
