/**
 * This interface defines a method that may be invoked if an unsolicited
 * notification is received from the directory server.  An unsolicited
 * notification handler should be defined in the {@link LDAPConnectionOptions}
 * for an {@link LDAPConnection} to be called whenever an unsolicited
 * notification is received for that connection.
 * 


 * An unsolicited notification is a type of extended response that is sent from
 * the server to the client without a corresponding request, and it may be used
 * to alert the client of a significant server-side event.  For example,
 * section 4.4.1 of RFC 4511
 * defines a notice of disconnection unsolicited notification that can be used
 *  by the server to inform the client that it is about to close the connection.
 * 


 * Implementations of this interface should be threadsafe to ensure that
 * multiple connections will be able to safely use the same
 * {@code UnsolicitedNotificationHandler} instance.
