| /** |
| * <p>The address of a JMX API connector server. Instances of this class |
| * are immutable.</p> |
| * |
| * <p>The address is an <em>Abstract Service URL</em> for SLP, as |
| * defined in RFC 2609 and amended by RFC 3111. It must look like |
| * this:</p> |
| * |
| * <blockquote> |
| * |
| * <code>service:jmx:<em>protocol</em>:<em>sap</em></code> |
| * |
| * </blockquote> |
| * |
| * <p>Here, <code><em>protocol</em></code> is the transport |
| * protocol to be used to connect to the connector server. It is |
| * a string of one or more ASCII characters, each of which is a |
| * letter, a digit, or one of the characters <code>+</code> or |
| * <code>-</code>. The first character must be a letter. |
| * Uppercase letters are converted into lowercase ones.</p> |
| * |
| * <p><code><em>sap</em></code> is the address at which the connector |
| * server is found. This address uses a subset of the syntax defined |
| * by RFC 2609 for IP-based protocols. It is a subset because the |
| * <code>user@host</code> syntax is not supported.</p> |
| * |
| * <p>The other syntaxes defined by RFC 2609 are not currently |
| * supported by this class.</p> |
| * |
| * <p>The supported syntax is:</p> |
| * |
| * <blockquote> |
| * |
| * <code>//<em>[host[</em>:<em>port]][url-path]</em></code> |
| * |
| * </blockquote> |
| * |
| * <p>Square brackets <code>[]</code> indicate optional parts of |
| * the address. Not all protocols will recognize all optional |
| * parts.</p> |
| * |
| * <p>The <code><em>host</em></code> is a host name, an IPv4 numeric |
| * host address, or an IPv6 numeric address enclosed in square |
| * brackets.</p> |
| * |
| * <p>The <code><em>port</em></code> is a decimal port number. 0 |
| * means a default or anonymous port, depending on the protocol.</p> |
| * |
| * <p>The <code><em>host</em></code> and <code><em>port</em></code> |
| * can be omitted. The <code><em>port</em></code> cannot be supplied |
| * without a <code><em>host</em></code>.</p> |
| * |
| * <p>The <code><em>url-path</em></code>, if any, begins with a slash |
| * (<code>/</code>) or a semicolon (<code>;</code>) and continues to |
| * the end of the address. It can contain attributes using the |
| * semicolon syntax specified in RFC 2609. Those attributes are not |
| * parsed by this class and incorrect attribute syntax is not |
| * detected.</p> |
| * |
| * <p>Although it is legal according to RFC 2609 to have a |
| * <code><em>url-path</em></code> that begins with a semicolon, not |
| * all implementations of SLP allow it, so it is recommended to avoid |
| * that syntax.</p> |
| * |
| * <p>Case is not significant in the initial |
| * <code>service:jmx:<em>protocol</em></code> string or in the host |
| * part of the address. Depending on the protocol, case can be |
| * significant in the <code><em>url-path</em></code>.</p> |
| * |
| * @see <a |
| * href="http://www.ietf.org/rfc/rfc2609.txt">RFC 2609, |
| * "Service Templates and <code>Service:</code> Schemes"</a> |
| * @see <a |
| * href="http://www.ietf.org/rfc/rfc3111.txt">RFC 3111, |
| * "Service Location Protocol Modifications for IPv6"</a> |
