Module bea.wlp.disc.uri

This module provides classes used to manipulate URIs.

The Uri class is the representation of a URI and has all of the methods necessary to manipulate the components of a URI, including template replacement for templatized URIs.

The UriRewriter class and its subclasses add the capability to parse a URI string from recognized javascript pseudo-protocol links. Such psuedo-protocol links are the result of client-side URL rewriting done by the DISC framework to support AJAX enabled portlets and desktops. Using a UriRewriter to instantiate a Uri, a user does not need foreknowledge about whether or not the URI has been rewritten by DISC. In this way, the same code can be used to transparently manipulate a URI whether or not it has been rewritten by DISC.

The UriRewriter classes provide a mechanism for manipulating target URIs for recognized proxy URIs, such as proxy URIs for remote portlets.

The UriRewriterFactory is used to select a UriRewriter that recognizes the URI string of interest. In this way, code can be written to transparently manipulate a target URI whether or not the URI has been rewritten into a proxy URI by the server. If the URI is a recognized proxy URI then the UriRewriterFactory will select the UriRewriter subclass that can provide access to the target URI. If the URI is a simple, direct, non-proxy URI then the base UriRewriter will be selected and will provide access to the target URI with the same methods as all other UriRewriters.
