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:    $Id$ Field Summary  ParsedURLData data      The data class we defer most things to.  String userAgent      Constructor Summary public   ParsedURL(String urlStr)      Construct a ParsedURL from the given url string. public   ParsedURL(URL url)      Construct a ParsedURL from the given java.net.URL instance.

Parameters:   urlStr - The string to try and parse as a URL ParsedURL public ParsedURL(URL url)(Code) Construct a ParsedURL from the given java.net.URL instance. This is useful if you already have a valid java.net.URL instance. This bypasses most of the parsing and hence is quicker and less prone to reinterpretation than converting the URL to a string before construction. Parameters:   url - The URL to "mimic". ParsedURL public ParsedURL(String baseStr, String urlStr)(Code) Construct a sub URL from two strings. Parameters:   baseStr - The 'parent' URL. Should be complete.

ParsedURL public ParsedURL(URL baseURL, String urlStr)(Code) Construct a sub URL from a base URL and a string for the sub url. Parameters:   baseURL - The 'parent' URL. Parameters:   urlStr - The 'sub' URL may be complete or partial.the missing pieces will be taken from the baseURL. ParsedURL public ParsedURL(ParsedURL baseURL, String urlStr)(Code) Construct a sub URL from a base ParsedURL and a string for the sub url. Parameters:   baseURL - The 'parent' URL. Parameters:   urlStr - The 'sub' URL may be complete or partial.the missing pieces will be taken from the baseURL. Method Detail checkGZIP public static InputStream checkGZIP(InputStream is) throws IOException(Code) This is a utility function others can call that checks if is is a GZIP stream if so it returns a GZIPInputStream that will decode the contents, otherwise it returns (or a buffered version of is) untouched. Parameters:   is - Stream that may potentially be a GZIP stream. complete public boolean complete()(Code) Returns true if the URL looks well formed and complete. This does not garuntee that the stream can be opened but is a good indication that things aren't totally messed up. equals public boolean equals(Object obj)(Code) Implement Object.equals. Relies heavily on the contained ParsedURLData's implementation of equals. getContentEncoding public String getContentEncoding()(Code) Returns the content encoding if available. This is only available for some protocols. getContentType public String getContentType()(Code) Returns the content type if available. This is only available for some protocols. getGlobalUserAgent public static String getGlobalUserAgent()(Code) getHandler public static synchronized ParsedURLProtocolHandler getHandler(String protocol)(Code) Returns the handler for a particular protocol. If protocol is null or no match is found in the handlers map it returns the default protocol handler. Parameters:   protocol - The protocol to get a handler for. getHost public String getHost()(Code) Returns the host for this URL, if any, null if there isn't one or it doesn't make sense for the protocol. getPath public String getPath()(Code) Returns the path for this URL, if any (where appropriate for the protocol this also includes the file, not just directory). Note that getPath appears in JDK 1.3 as a synonym for getFile from JDK 1.2. getPort public int getPort()(Code) Returns the port on the host to connect to, if it was specified in the url that was parsed, otherwise returns -1. getPortStr public String getPortStr()(Code) Returns the URL up to and include the port number on the host. Does not include the path or fragment pieces. getProtocol public String getProtocol()(Code) Returns the protocol for this URL. The protocol is everything upto the first ':'. getProtocol protected static String getProtocol(String urlStr)(Code) Parse out the protocol from a url string. Used internally to select the proper handler, all other parsing is done by the selected protocol handler. getRef public String getRef()(Code) Returns the 'fragment' reference in the URL. getUserAgent public String getUserAgent()(Code) Return the user agent current associated with this url (or null if none). hashCode public int hashCode()(Code) Implement Object.hashCode. Relies on the contained ParsedURLData's implementation of hashCode. openStream public InputStream openStream() throws IOException(Code) Attempt to open the stream checking for common compression types, and automatically decompressing them if found. openStream public InputStream openStream(String mimeType) throws IOException(Code) Attempt to open the stream checking for common compression types, and automatically decompressing them if found.
