| 30 | +/** | |
| 31 | + * An abstraction that identifies a target host and communications | |
| 32 | + * protocol. The HostIdentifier, or hostid, provides a convenient string | |
| 33 | + * representation of the information needed to locate and communicate with | |
| 34 | + * a target host. The string, based on a {@link URI}, may specify the | |
| 35 | + * the communications protocol, host name, and protocol specific information | |
| 36 | + * for a target host. The format for a HostIdentifier string is: | |
| 37 | + * <pre> | |
| 38 | + * [<I>protocol</I>:][[<I>//</I>]<I>hostname</I>][<I>:port</I>][<I>/servername</I>] | |
| 39 | + * </pre> | |
| 40 | + * There are actually no required components of this string, as a null string | |
| 41 | + * is interpreted to mean a local connection to the local host and is equivalent | |
| 42 | + * to the string <em>local://localhost</em>. The components of the | |
| 43 | + * HostIdentifier are: | |
| 44 | + * <ul> | |
| 45 | + * <li><p><tt>protocol</tt> - The communications protocol. If omitted, | |
| 46 | + * and a hostname is not specified, then default local protocol, | |
| 47 | + * <em>local:</em>, is assumed. If the protocol is omitted and a | |
| 48 | + * hostname is specified then the default remote protocol, | |
| 49 | + * <em>rmi:</em> is assumed. | |
| 50 | + * </p></li> | |
| 51 | + * <li><p><tt>hostname</tt> - The hostname. If omitted, then | |
| 52 | + * <em>localhost</em> is assumed. If the protocol is also omitted, | |
| 53 | + * then default local protocol <em>local:</em> is also assumed. | |
| 54 | + * If the hostname is not omitted but the protocol is omitted, | |
| 55 | + * then the default remote protocol, <em>rmi:</em> is assumed. | |
| 56 | + * </p></li> | |
| 57 | + * <li><p><tt>port</tt> - The port for the communications protocol. | |
| 58 | + * Treatment of the <tt>port</tt> parameter is implementation | |
| 59 | + * (protocol) specific. It is unused by the default local protocol, | |
| 60 | + * <em>local:</em>. For the default remote protocol, <em>rmi:</em>, | |
| 61 | + * <tt>port</tt> indicates the port number of the <em>rmiregistry</em> | |
| 62 | + * on the target host and defaults to port 1099. | |
| 63 | + * </p></li> | |
| 64 | + * <li><p><tt>servername</tt> - The treatment of the Path, Query, and | |
| 65 | + * Fragment components of the HostIdentifier are implementation | |
| 66 | + * (protocol) dependent. These components are ignored by the | |
| 67 | + * default local protocol, <em>local:</em>. For the default remote | |
| 68 | + * protocol, <em>rmi</em>, the Path component is interpreted as | |
| 69 | + * the name of the RMI remote object. The Query component may | |
| 70 | + * contain an access mode specifier <em>?mode=</em> specifying | |
| 71 | + * <em>"r"</em> or <em>"rw"</em> access (write access currently | |
| 72 | + * ignored). The Fragment part is ignored. | |
| 73 | + * </p></li> | |
| 74 | + * </ul> | |
| 75 | + * <p> | |
| 76 | + * All HostIdentifier objects are represented as absolute, hierarchical URIs. | |
| 77 | + * The constructors accept relative URIs, but these will generally be | |
| 78 | + * transformed into an absolute URI specifying a default protocol. A | |
| 79 | + * HostIdentifier differs from a URI in that certain contractions and | |
| 80 | + * illicit syntactical constructions are allowed. The following are all | |
| 81 | + * valid HostIdentifier strings: | |
| 82 | + * | |
| 83 | + * <ul> | |
| 84 | + * <li><p>< null > - transformed into "//localhost"</p></li> | |
| 85 | + * <li><p>localhost - transformed into "//localhost"</p></li> | |
| 86 | + * <li><p>hostname - transformed into "//hostname"</p></li> | |
| 87 | + * <li><p>hostname:port - transformed into "//hostname:port"</p></li> | |
| 88 | + * <li><p>proto:hostname - transformed into "proto://hostname"</p></li> | |
| 89 | + * <li><p>proto:hostname:port - transformed into | |
| 90 | + * "proto://hostname:port"</p></li> | |
| 91 | + * <li><p>proto://hostname:port</p></li> | |
| 92 | + * </ul> | |
