| /** |
| * Represents a Uniform Resource Identifier (URI) reference. |
| * |
| * <p> Aside from some minor deviations noted below, an instance of this |
| * class represents a URI reference as defined by |
| * <a href="http://www.ietf.org/rfc/rfc2396.txt"><i>RFC 2396: Uniform |
| * Resource Identifiers (URI): Generic Syntax</i></a>, amended by <a |
| * href="http://www.ietf.org/rfc/rfc2732.txt"><i>RFC 2732: Format for |
| * Literal IPv6 Addresses in URLs</i></a>. The Literal IPv6 address format |
| * also supports scope_ids. The syntax and usage of scope_ids is described |
| * <a href="Inet6Address.html#scoped">here</a>. |
| * This class provides constructors for creating URI instances from |
| * their components or by parsing their string forms, methods for accessing the |
| * various components of an instance, and methods for normalizing, resolving, |
| * and relativizing URI instances. Instances of this class are immutable. |
| * |
| * |
| * <h3> URI syntax and components </h3> |
| * |
| * At the highest level a URI reference (hereinafter simply "URI") in string |
| * form has the syntax |
| * |
| * <blockquote> |
| * [<i>scheme</i><b>{@code :}</b>]<i>scheme-specific-part</i>[<b>{@code #}</b><i>fragment</i>] |
| * </blockquote> |
| * |
| * where square brackets [...] delineate optional components and the characters |
| * <b>{@code :}</b> and <b>{@code #}</b> stand for themselves. |
| * |
| * <p> An <i>absolute</i> URI specifies a scheme; a URI that is not absolute is |
| * said to be <i>relative</i>. URIs are also classified according to whether |
| * they are <i>opaque</i> or <i>hierarchical</i>. |
| * |
| * <p> An <i>opaque</i> URI is an absolute URI whose scheme-specific part does |
| * not begin with a slash character ({@code '/'}). Opaque URIs are not |
| * subject to further parsing. Some examples of opaque URIs are: |
| * |
| * <blockquote><table cellpadding=0 cellspacing=0 summary="layout"> |
| * <tr><td>{@code mailto:java-net@java.sun.com}<td></tr> |
| * <tr><td>{@code news:comp.lang.java}<td></tr> |
| * <tr><td>{@code urn:isbn:096139210x}</td></tr> |
| * </table></blockquote> |
| * |
| * <p> A <i>hierarchical</i> URI is either an absolute URI whose |
| * scheme-specific part begins with a slash character, or a relative URI, that |
| * is, a URI that does not specify a scheme. Some examples of hierarchical |
| * URIs are: |
| * |
| * <blockquote> |
| * {@code http://java.sun.com/j2se/1.3/}<br> |
| * {@code docs/guide/collections/designfaq.html#28}<br> |
| * {@code ../../../demo/jfc/SwingSet2/src/SwingSet2.java}<br> |
| * {@code file:///~/calendar} |
| * </blockquote> |
| * |
| * <p> A hierarchical URI is subject to further parsing according to the syntax |
| * |
| * <blockquote> |
| * [<i>scheme</i><b>{@code :}</b>][<b>{@code //}</b><i>authority</i>][<i>path</i>][<b>{@code ?}</b><i>query</i>][<b>{@code #}</b><i>fragment</i>] |
| * </blockquote> |
| * |
| * where the characters <b>{@code :}</b>, <b>{@code /}</b>, |
| * <b>{@code ?}</b>, and <b>{@code #}</b> stand for themselves. The |
| * scheme-specific part of a hierarchical URI consists of the characters |
| * between the scheme and fragment components. |
| * |
| * <p> The authority component of a hierarchical URI is, if specified, either |
| * <i>server-based</i> or <i>registry-based</i>. A server-based authority |
| * parses according to the familiar syntax |
| * |
| * <blockquote> |
| * [<i>user-info</i><b>{@code @}</b>]<i>host</i>[<b>{@code :}</b><i>port</i>] |
| * </blockquote> |
| * |
| * where the characters <b>{@code @}</b> and <b>{@code :}</b> stand for |
| * themselves. Nearly all URI schemes currently in use are server-based. An |
| * authority component that does not parse in this way is considered to be |
| * registry-based. |
| * |
| * <p> The path component of a hierarchical URI is itself said to be absolute |
| * if it begins with a slash character ({@code '/'}); otherwise it is |
| * relative. The path of a hierarchical URI that is either absolute or |
| * specifies an authority is always absolute. |
| * |
| * <p> All told, then, a URI instance has the following nine components: |
| * |
| * <blockquote><table summary="Describes the components of a URI:scheme,scheme-specific-part,authority,user-info,host,port,path,query,fragment"> |
| * <tr><th><i>Component</i></th><th><i>Type</i></th></tr> |
| * <tr><td>scheme</td><td>{@code String}</td></tr> |
| * <tr><td>scheme-specific-part </td><td>{@code String}</td></tr> |
| * <tr><td>authority</td><td>{@code String}</td></tr> |
| * <tr><td>user-info</td><td>{@code String}</td></tr> |
| * <tr><td>host</td><td>{@code String}</td></tr> |
| * <tr><td>port</td><td>{@code int}</td></tr> |
| * <tr><td>path</td><td>{@code String}</td></tr> |
| * <tr><td>query</td><td>{@code String}</td></tr> |
| * <tr><td>fragment</td><td>{@code String}</td></tr> |
| * </table></blockquote> |
| * |
| * In a given instance any particular component is either <i>undefined</i> or |
| * <i>defined</i> with a distinct value. Undefined string components are |
| * represented by {@code null}, while undefined integer components are |
| * represented by {@code -1}. A string component may be defined to have the |
| * empty string as its value; this is not equivalent to that component being |
| * undefined. |
| * |
| * <p> Whether a particular component is or is not defined in an instance |
| * depends upon the type of the URI being represented. An absolute URI has a |
| * scheme component. An opaque URI has a scheme, a scheme-specific part, and |
| * possibly a fragment, but has no other components. A hierarchical URI always |
| * has a path (though it may be empty) and a scheme-specific-part (which at |
| * least contains the path), and may have any of the other components. If the |
| * authority component is present and is server-based then the host component |
| * will be defined and the user-information and port components may be defined. |
| * |
| * |
| * <h4> Operations on URI instances </h4> |
| * |
| * The key operations supported by this class are those of |
| * <i>normalization</i>, <i>resolution</i>, and <i>relativization</i>. |
| * |
| * <p> <i>Normalization</i> is the process of removing unnecessary {@code "."} |
| * and {@code ".."} segments from the path component of a hierarchical URI. |
| * Each {@code "."} segment is simply removed. A {@code ".."} segment is |
| * removed only if it is preceded by a non-{@code ".."} segment. |
| * Normalization has no effect upon opaque URIs. |
| * |
| * <p> <i>Resolution</i> is the process of resolving one URI against another, |
| * <i>base</i> URI. The resulting URI is constructed from components of both |
| * URIs in the manner specified by RFC 2396, taking components from the |
| * base URI for those not specified in the original. For hierarchical URIs, |
| * the path of the original is resolved against the path of the base and then |
| * normalized. The result, for example, of resolving |
| * |
| * <blockquote> |
| * {@code docs/guide/collections/designfaq.html#28} |
| * |
| * (1) |
| * </blockquote> |
| * |
| * against the base URI {@code http://java.sun.com/j2se/1.3/} is the result |
| * URI |
| * |
| * <blockquote> |
| * {@code http://java.sun.com/j2se/1.3/docs/guide/collections/designfaq.html#28} |
| * </blockquote> |
| * |
| * Resolving the relative URI |
| * |
| * <blockquote> |
| * {@code ../../../demo/jfc/SwingSet2/src/SwingSet2.java} (2) |
| * </blockquote> |
| * |
| * against this result yields, in turn, |
| * |
| * <blockquote> |
| * {@code http://java.sun.com/j2se/1.3/demo/jfc/SwingSet2/src/SwingSet2.java} |
| * </blockquote> |
| * |
| * Resolution of both absolute and relative URIs, and of both absolute and |
| * relative paths in the case of hierarchical URIs, is supported. Resolving |
| * the URI {@code file:///~calendar} against any other URI simply yields the |
| * original URI, since it is absolute. Resolving the relative URI (2) above |
| * against the relative base URI (1) yields the normalized, but still relative, |
| * URI |
| * |
| * <blockquote> |
| * {@code demo/jfc/SwingSet2/src/SwingSet2.java} |
| * </blockquote> |
| * |
| * <p> <i>Relativization</i>, finally, is the inverse of resolution: For any |
| * two normalized URIs <i>u</i> and <i>v</i>, |
| * |
| * <blockquote> |
| * <i>u</i>{@code .relativize(}<i>u</i>{@code .resolve(}<i>v</i>{@code )).equals(}<i>v</i>{@code )} and<br> |
| * <i>u</i>{@code .resolve(}<i>u</i>{@code .relativize(}<i>v</i>{@code )).equals(}<i>v</i>{@code )} .<br> |
| * </blockquote> |
| * |
| * This operation is often useful when constructing a document containing URIs |
| * that must be made relative to the base URI of the document wherever |
| * possible. For example, relativizing the URI |
| * |
| * <blockquote> |
| * {@code http://java.sun.com/j2se/1.3/docs/guide/index.html} |
| * </blockquote> |
| * |
| * against the base URI |
| * |
| * <blockquote> |
| * {@code http://java.sun.com/j2se/1.3} |
| * </blockquote> |
| * |
| * yields the relative URI {@code docs/guide/index.html}. |
| * |
| * |
| * <h4> Character categories </h4> |
| * |
| * RFC 2396 specifies precisely which characters are permitted in the |
| * various components of a URI reference. The following categories, most of |
| * which are taken from that specification, are used below to describe these |
| * constraints: |
| * |
| * <blockquote><table cellspacing=2 summary="Describes categories alpha,digit,alphanum,unreserved,punct,reserved,escaped,and other"> |
| * <tr><th valign=top><i>alpha</i></th> |
| * <td>The US-ASCII alphabetic characters, |
| * {@code 'A'} through {@code 'Z'} |
| * and {@code 'a'} through {@code 'z'}</td></tr> |
| * <tr><th valign=top><i>digit</i></th> |
| * <td>The US-ASCII decimal digit characters, |
| * {@code '0'} through {@code '9'}</td></tr> |
| * <tr><th valign=top><i>alphanum</i></th> |
| * <td>All <i>alpha</i> and <i>digit</i> characters</td></tr> |
| * <tr><th valign=top><i>unreserved</i> </th> |
| * <td>All <i>alphanum</i> characters together with those in the string |
| * {@code "_-!.~'()*"}</td></tr> |
| * <tr><th valign=top><i>punct</i></th> |
| * <td>The characters in the string {@code ",;:$&+="}</td></tr> |
| * <tr><th valign=top><i>reserved</i></th> |
| * <td>All <i>punct</i> characters together with those in the string |
| * {@code "?/[]@"}</td></tr> |
| * <tr><th valign=top><i>escaped</i></th> |
| * <td>Escaped octets, that is, triplets consisting of the percent |
| * character ({@code '%'}) followed by two hexadecimal digits |
| * ({@code '0'}-{@code '9'}, {@code 'A'}-{@code 'F'}, and |
| * {@code 'a'}-{@code 'f'})</td></tr> |
| * <tr><th valign=top><i>other</i></th> |
| * <td>The Unicode characters that are not in the US-ASCII character set, |
| * are not control characters (according to the {@link |
| * java.lang.Character#isISOControl(char) Character.isISOControl} |
| * method), and are not space characters (according to the {@link |
| * java.lang.Character#isSpaceChar(char) Character.isSpaceChar} |
| * method) <i>(<b>Deviation from RFC 2396</b>, which is |
| * limited to US-ASCII)</i></td></tr> |
| * </table></blockquote> |
| * |
| * <p><a name="legal-chars"></a> The set of all legal URI characters consists of |
| * the <i>unreserved</i>, <i>reserved</i>, <i>escaped</i>, and <i>other</i> |
| * characters. |
| * |
| * |
| * <h4> Escaped octets, quotation, encoding, and decoding </h4> |
| * |
| * RFC 2396 allows escaped octets to appear in the user-info, path, query, and |
| * fragment components. Escaping serves two purposes in URIs: |
| * |
| * <ul> |
| * |
| * <li><p> To <i>encode</i> non-US-ASCII characters when a URI is required to |
| * conform strictly to RFC 2396 by not containing any <i>other</i> |
| * characters. </p></li> |
| * |
| * <li><p> To <i>quote</i> characters that are otherwise illegal in a |
| * component. The user-info, path, query, and fragment components differ |
| * slightly in terms of which characters are considered legal and illegal. |
| * </p></li> |
| * |
| * </ul> |
| * |
| * These purposes are served in this class by three related operations: |
| * |
| * <ul> |
| * |
| * <li><p><a name="encode"></a> A character is <i>encoded</i> by replacing it |
| * with the sequence of escaped octets that represent that character in the |
| * UTF-8 character set. The Euro currency symbol ({@code '\u005Cu20AC'}), |
| * for example, is encoded as {@code "%E2%82%AC"}. <i>(<b>Deviation from |
| * RFC 2396</b>, which does not specify any particular character |
| * set.)</i> </p></li> |
| * |
| * <li><p><a name="quote"></a> An illegal character is <i>quoted</i> simply by |
| * encoding it. The space character, for example, is quoted by replacing it |
| * with {@code "%20"}. UTF-8 contains US-ASCII, hence for US-ASCII |
| * characters this transformation has exactly the effect required by |
| * RFC 2396. </p></li> |
| * |
| * <li><p><a name="decode"></a> |
| * A sequence of escaped octets is <i>decoded</i> by |
| * replacing it with the sequence of characters that it represents in the |
| * UTF-8 character set. UTF-8 contains US-ASCII, hence decoding has the |
| * effect of de-quoting any quoted US-ASCII characters as well as that of |
| * decoding any encoded non-US-ASCII characters. If a <a |
| * href="../nio/charset/CharsetDecoder.html#ce">decoding error</a> occurs |
| * when decoding the escaped octets then the erroneous octets are replaced by |
| * {@code '\u005CuFFFD'}, the Unicode replacement character. </p></li> |
| * |
| * </ul> |
| * |
| * These operations are exposed in the constructors and methods of this class |
| * as follows: |
| * |
| * <ul> |
| * |
| * <li><p> The {@linkplain #URI(java.lang.String) single-argument |
| * constructor} requires any illegal characters in its argument to be |
| * quoted and preserves any escaped octets and <i>other</i> characters that |
| * are present. </p></li> |
| * |
| * <li><p> The {@linkplain |
| * #URI(java.lang.String,java.lang.String,java.lang.String,int,java.lang.String,java.lang.String,java.lang.String) |
| * multi-argument constructors} quote illegal characters as |
| * required by the components in which they appear. The percent character |
| * ({@code '%'}) is always quoted by these constructors. Any <i>other</i> |
| * characters are preserved. </p></li> |
| * |
| * <li><p> The {@link #getRawUserInfo() getRawUserInfo}, {@link #getRawPath() |
| * getRawPath}, {@link #getRawQuery() getRawQuery}, {@link #getRawFragment() |
| * getRawFragment}, {@link #getRawAuthority() getRawAuthority}, and {@link |
| * #getRawSchemeSpecificPart() getRawSchemeSpecificPart} methods return the |
| * values of their corresponding components in raw form, without interpreting |
| * any escaped octets. The strings returned by these methods may contain |
| * both escaped octets and <i>other</i> characters, and will not contain any |
| * illegal characters. </p></li> |
| * |
| * <li><p> The {@link #getUserInfo() getUserInfo}, {@link #getPath() |
| * getPath}, {@link #getQuery() getQuery}, {@link #getFragment() |
| * getFragment}, {@link #getAuthority() getAuthority}, and {@link |
| * #getSchemeSpecificPart() getSchemeSpecificPart} methods decode any escaped |
| * octets in their corresponding components. The strings returned by these |
| * methods may contain both <i>other</i> characters and illegal characters, |
| * and will not contain any escaped octets. </p></li> |
| * |
| * <li><p> The {@link #toString() toString} method returns a URI string with |
| * all necessary quotation but which may contain <i>other</i> characters. |
| * </p></li> |
| * |
| * <li><p> The {@link #toASCIIString() toASCIIString} method returns a fully |
| * quoted and encoded URI string that does not contain any <i>other</i> |
| * characters. </p></li> |
| * |
| * </ul> |
| * |
| * |
| * <h4> Identities </h4> |
| * |
| * For any URI <i>u</i>, it is always the case that |
| * |
| * <blockquote> |
| * {@code new URI(}<i>u</i>{@code .toString()).equals(}<i>u</i>{@code )} . |
| * </blockquote> |
| * |
| * For any URI <i>u</i> that does not contain redundant syntax such as two |
| * slashes before an empty authority (as in {@code file:///tmp/} ) or a |
| * colon following a host name but no port (as in |
| * {@code http://java.sun.com:} ), and that does not encode characters |
| * except those that must be quoted, the following identities also hold: |
| * <pre> |
| * new URI(<i>u</i>.getScheme(), |
| * <i>u</i>.getSchemeSpecificPart(), |
| * <i>u</i>.getFragment()) |
| * .equals(<i>u</i>)</pre> |
| * in all cases, |
| * <pre> |
| * new URI(<i>u</i>.getScheme(), |
| * <i>u</i>.getUserInfo(), <i>u</i>.getAuthority(), |
| * <i>u</i>.getPath(), <i>u</i>.getQuery(), |
| * <i>u</i>.getFragment()) |
| * .equals(<i>u</i>)</pre> |
| * if <i>u</i> is hierarchical, and |
| * <pre> |
| * new URI(<i>u</i>.getScheme(), |
| * <i>u</i>.getUserInfo(), <i>u</i>.getHost(), <i>u</i>.getPort(), |
| * <i>u</i>.getPath(), <i>u</i>.getQuery(), |
| * <i>u</i>.getFragment()) |
| * .equals(<i>u</i>)</pre> |
| * if <i>u</i> is hierarchical and has either no authority or a server-based |
| * authority. |
| * |
| * |
| * <h4> URIs, URLs, and URNs </h4> |
| * |
| * A URI is a uniform resource <i>identifier</i> while a URL is a uniform |
| * resource <i>locator</i>. Hence every URL is a URI, abstractly speaking, but |
| * not every URI is a URL. This is because there is another subcategory of |
| * URIs, uniform resource <i>names</i> (URNs), which name resources but do not |
| * specify how to locate them. The {@code mailto}, {@code news}, and |
| * {@code isbn} URIs shown above are examples of URNs. |
| * |
| * <p> The conceptual distinction between URIs and URLs is reflected in the |
| * differences between this class and the {@link java.net.URL URL} class. |
| * |
| * <p> An instance of this class represents a URI reference in the syntactic |
| * sense defined by RFC 2396. A URI may be either absolute or relative. |
| * A URI string is parsed according to the generic syntax without regard to the |
| * scheme, if any, that it specifies. No lookup of the host, if any, is |
| * performed, and no scheme-dependent stream handler is constructed. Equality, |
| * hashing, and comparison are defined strictly in terms of the character |
| * content of the instance. In other words, a URI instance is little more than |
| * a structured string that supports the syntactic, scheme-independent |
| * operations of comparison, normalization, resolution, and relativization. |
| * |
| * <p> An instance of the {@link java.net.URL URL} class, by contrast, represents the |
| * syntactic components of a URL together with some of the information required |
| * to access the resource that it describes. A URL must be absolute, that is, |
| * it must always specify a scheme. A URL string is parsed according to its |
| * scheme. A stream handler is always established for a URL, and in fact it is |
| * impossible to create a URL instance for a scheme for which no handler is |
| * available. Equality and hashing depend upon both the scheme and the |
| * Internet address of the host, if any; comparison is not defined. In other |
| * words, a URL is a structured string that supports the syntactic operation of |
| * resolution as well as the network I/O operations of looking up the host and |
| * opening a connection to the specified resource. |

| * |
| * <ul> |
| * |
| * <li><p> An empty authority component is permitted as long as it is |
| * followed by a non-empty path, a query component, or a fragment |
| * component. This allows the parsing of URIs such as |
| * {@code "file:///foo/bar"}, which seems to be the intent of |
| * RFC 2396 although the grammar does not permit it. If the |
| * authority component is empty then the user-information, host, and port |
| * components are undefined. </p></li> |
| * |
| * <li><p> Empty relative paths are permitted; this seems to be the |
| * intent of RFC 2396 although the grammar does not permit it. The |
| * primary consequence of this deviation is that a standalone fragment |
| * such as {@code "#foo"} parses as a relative URI with an empty path |
| * and the given fragment, and can be usefully <a |
| * href="#resolve-frag">resolved</a> against a base URI. |
| * |
| * <li><p> IPv4 addresses in host components are parsed rigorously, as |
| * specified by <a |
| * href="http://www.ietf.org/rfc/rfc2732.txt">RFC 2732</a>: Each |
| * element of a dotted-quad address must contain no more than three |

| * no greater than 255. </p></li> |
| * |
| * <li> <p> Hostnames in host components that comprise only a single |
| * domain label are permitted to start with an <i>alphanum</i> |
| * character. This seems to be the intent of <a |
| * href="http://www.ietf.org/rfc/rfc2396.txt">RFC 2396</a> |
| * section 3.2.2 although the grammar does not permit it. The |

| * IPv6 address itself must parse according to <a |
