Class Handler

  • All Implemented Interfaces:
    IJarURLStreamHandler

    public class Handler
    extends java.net.URLStreamHandler
    implements IJarURLStreamHandler
    The memory Jar URLStreamHandler.

    This class must be named Handler for the default system handler search mechanism to function. Normally you will not use this class directly; NpURLStreamHandlerFactory documents how to globally install memjar support.
