aoqi@0 36 * A class to represent a Uniform Resource Identifier (URI). This class
aoqi@0 37 * is designed to handle the parsing of URIs and provide access to
aoqi@0 38 * the various components (scheme, host, port, userinfo, path, query
aoqi@0 39 * string and fragment) that may constitute a URI.
aoqi@0 40 * <p>
aoqi@0 41 * Parsing of a URI specification is done according to the URI
aoqi@0 42 * syntax described in RFC 2396
aoqi@0 43 * <http://www.ietf.org/rfc/rfc2396.txt?number=2396>. Every URI consists
aoqi@0 44 * of a scheme, followed by a colon (':'), followed by a scheme-specific
aoqi@0 45 * part. For URIs that follow the "generic URI" syntax, the scheme-
aoqi@0 46 * specific part begins with two slashes ("//") and may be followed
aoqi@0 47 * by an authority segment (comprised of user information, host, and
aoqi@0 48 * port), path segment, query segment and fragment. Note that RFC 2396
aoqi@0 49 * no longer specifies the use of the parameters segment and excludes
aoqi@0 50 * the "user:password" syntax as part of the authority segment. If
aoqi@0 51 * "user:password" appears in a URI, the entire user/password string
aoqi@0 52 * is stored as userinfo.
aoqi@0 53 * <p>
aoqi@0 54 * For URIs that do not follow the "generic URI" syntax (e.g. mailto),
aoqi@0 55 * the entire scheme-specific part is treated as the "path" portion
aoqi@0 56 * of the URI.
aoqi@0 57 * <p>
aoqi@0 58 * Note that, unlike the java.net.URL class, this class does not provide
aoqi@0 59 * any built-in network access functionality nor does it provide any
aoqi@0 60 * scheme-specific functionality (for example, it does not know a
aoqi@0 61 * default port for a specific scheme). Rather, it only knows the
aoqi@0 62 * grammar and basic set of operations that can be applied to a URI.
