/**
 * This class defines a monitor entry that provides general information about
 * the client connections currently established.  Note that the information
 * available for each client connection may vary based on the type of connection
 * handler with which that connection is associated.
 * 

 * 
 *   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.
 * 
 * 

 * The server should present at most one client connection monitor entry.  It
 * can be retrieved using the
 * {@link MonitorManager#getClientConnectionMonitorEntry} method.  The
 * {@link ClientConnectionMonitorEntry#getConnections} method may be used to
 * retrieve information for each connection.  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.
