/**
 * 

 *   NOTE:  This class is part of the Commercial Edition of the UnboundID
 *   LDAP SDK for Java.  It is not available for use in applications that
 *   include only the Standard Edition of the LDAP SDK, and is not supported for
 *   use in conjunction with non-UnboundID products.
 * 
 * This class defines a monitor entry that provides information about the state
 * of a replication server, including the base DNs for replicated content, the
 * generation ID for each of those base DNs, the replication server ID, and the
 * port number on which the replication server is listening.
 * 


 * The server should present at most one replication server monitor entry.  It
 * can be retrieved using the
 * {@link MonitorManager#getReplicationServerMonitorEntry} method.  This entry
 * provides specific methods for accessing information about the replication
 * server.  Alternately, this information may be accessed using the generic API.
 * See the {@link MonitorManager} class documentation for an example that
 * demonstrates the use of the generic API for accessing monitor data.
