Examples of ServerName

com.alibaba.wasp.ServerName
Instance of an Wasp ServerName. A server name is used uniquely identifying a server instance and is made of the combination of hostname, port, and startcode. The startcode distingushes restarted servers on same hostname and port (startcode is usually timestamp of server startup). The {@link #toString()} format of ServerName is safe to use in the filesystem andas znode name up in ZooKeeper. Its format is: <hostname> ' {@link #SERVERNAME_SEPARATOR}' <port> ' {@link #SERVERNAME_SEPARATOR}' <startcode> . For example, if hostname is example.org, port is 1234, and the startcode for the fserver is 1212121212, then the {@link #toString()} would beexample.org,1234,1212121212.
You can obtain a versioned serialized form of this class by calling {@link #getVersionedBytes()}. To deserialize, call {@link #parseVersionedServerName(byte[])}
Immutable.
