Class DefaultClassLoader

java.lang.Object
  edu.ksu.cis.projects.bogor.module.DefaultClassLoader

All Implemented Interfaces:

IClassLoader, IModule, Disposable

public class DefaultClassLoader
extends Object
implements IClassLoader

Hook for plugin modules to allow clients which do not explicitly depend on the plugin, to still load classes from it. This works around Eclipse's classloader isolation architecture.

This getInstance() method is marked final because each plugin must implement getInstance() sepately in order to force its own classloader to perform the work.
