Class Handler

  • All Implemented Interfaces:
    IJarURLStreamHandler
    public class Handler
extends java.net.URLStreamHandler
implements IJarURLStreamHandler
    The XJar URLStreamHandler.

    This class must be named Handler for the default system handler search mechanism to function. Normally you will not use this class directly; XURLStreamHandlerFactory documents how to globally install Xjar support. However, you can employ XJar using just this class:

       Handler xjar = new Handler(...);
   URL url = new URL (..., xjar);
