public class DelegateClassLoader

extends java.lang.ClassLoader

ClassLoader that delegates class loading requests if the parent ClassLoader (and its ancestors) can't fulfill the request. Class loading requests are handed off to scouts, which are called upon in sequence to find the class, until the class is found. If neither the parent or scouts can find a requested class, a normal ClassNotFoundException is thrown.
