| /** |
| * A class to represent a Uniform Resource Identifier (URI). This class |
| * is designed to handle the parsing of URIs and provide access to |
| * the various components (scheme, host, port, userinfo, path, query |
| * string and fragment) that may constitute a URI. |
| * <p> |
| * Parsing of a URI specification is done according to the URI |
| * syntax described in RFC 2396 |
| * <http://www.ietf.org/rfc/rfc2396.txt?number=2396>. Every URI consists |
| * of a scheme, followed by a colon (':'), followed by a scheme-specific |
| * part. For URIs that follow the "generic URI" syntax, the scheme- |
| * specific part begins with two slashes ("//") and may be followed |
| * by an authority segment (comprised of user information, host, and |
| * port), path segment, query segment and fragment. Note that RFC 2396 |
| * no longer specifies the use of the parameters segment and excludes |
| * the "user:password" syntax as part of the authority segment. If |
| * "user:password" appears in a URI, the entire user/password string |
| * is stored as userinfo. |
| * <p> |
| * For URIs that do not follow the "generic URI" syntax (e.g. mailto), |
| * the entire scheme-specific part is treated as the "path" portion |
| * of the URI. |
| * <p> |
| * Note that, unlike the java.net.URL class, this class does not provide |
| * any built-in network access functionality nor does it provide any |
| * scheme-specific functionality (for example, it does not know a |
| * default port for a specific scheme). Rather, it only knows the |
| * grammar and basic set of operations that can be applied to a URI. |
