Class CompositeClassloader

  • public class CompositeClassloader
extends java.lang.ClassLoader
    A composite classloader that has a parent classloader and an alternate classloader.

    When resolving classes, the parent classloader is consulted first, and if that classloader cannot find the class, the alternate/second classloader is asked to resolve the class.
