Examples of org.apache.batik.util.ParsedURL

org.apache.batik.util.ParsedURL
This class is used as a replacement for java.net.URL. This is done for several reasons. First unlike java.net.URL this class will accept and parse as much of a URL as possible, without throwing a MalformedURL exception. This makes it extreamly useful for simply parsing a URL string (hence it's name). Second it allows for extension of the protocols supported by the URL parser. Batik uses this to support the 'Data' protocol. Third by default it checks the streams that it opens to see if they are GZIP compressed, if so it automatically uncompresses them (avoiding opening the stream twice in the processes). It is worth noting that most real work is defered to the ParsedURLData class to which most methods are forwarded. This is done because it allows a constructor interface to ParsedURL (mostly for compatability with core URL), in spite of the fact that the real implemenation uses the protocol handlers as factories for protocol specific instances of the ParsedURLData class. @author Thomas DeWeese @version $Id: ParsedURL.java,v 1.14 2002/08/01 20:24:32 deweese Exp $
