31 /**
32 * A class to represent a Uniform Resource Identifier (URI). This class
33 * is designed to handle the parsing of URIs and provide access to
34 * the various components (scheme, host, port, userinfo, path, query
35 * string and fragment) that may constitute a URI.
36 * <p>
37 * Parsing of a URI specification is done according to the URI
38 * syntax described in RFC 2396
39 * <http://www.ietf.org/rfc/rfc2396.txt?number=2396>. Every URI consists
40 * of a scheme, followed by a colon (':'), followed by a scheme-specific
41 * part. For URIs that follow the "generic URI" syntax, the scheme-
42 * specific part begins with two slashes ("//") and may be followed
43 * by an authority segment (comprised of user information, host, and
44 * port), path segment, query segment and fragment. Note that RFC 2396
45 * no longer specifies the use of the parameters segment and excludes
46 * the "user:password" syntax as part of the authority segment. If
47 * "user:password" appears in a URI, the entire user/password string
48 * is stored as userinfo.
49 * <p>
50 * For URIs that do not follow the "generic URI" syntax (e.g. mailto),
51 * the entire scheme-specific part is treated as the "path" portion
52 * of the URI.
53 * <p>
54 * Note that, unlike the java.net.URL class, this class does not provide
55 * any built-in network access functionality nor does it provide any
56 * scheme-specific functionality (for example, it does not know a
57 * default port for a specific scheme). Rather, it only knows the
58 * grammar and basic set of operations that can be applied to a URI.
