Class ReloadingClassLoader

  • All Implemented Interfaces:
    ReloadNotificationListener
    public class ReloadingClassLoader
extends java.lang.ClassLoader
implements ReloadNotificationListener
    The ReloadingClassLoader uses a delegation mechansim to allow classes to be reloaded. That means that loadClass calls may return different results if the class was changed in the underlying ResourceStore.
