      • URLClassPath

        public URLClassPath​(String host,
                            int port,
                            String directory,
                            String packageName)
        Creates a search path specified with URL (http).

        This search path is used only if a requested class name starts with the name specified by packageName. If packageName is "org.javassist." and a requested class is "org.javassist.test.Main", then the given URL is used for loading that class. The URLClassPath obtains a class file from:

        http://www.javassist.org:80/java/classes/org/javassist/test/Main.class
         

        Here, we assume that host is "www.javassist.org", port is 80, and directory is "/java/classes/".

        If packageName is null, the URL is used for loading any class.

        Parameters:
        host - host name
        port - port number
        directory - directory name ending with "/". It can be "/" (root directory). It must start with "/".
        packageName - package name. It must end with "." (dot).
