 * adapter classes to provide transparent RMI access to remote locks.
 * <p>
 * The methods in this interface are documented only with a reference
 * to a corresponding Lock method. The remote object will simply forward
 * the method call to the underlying Lock instance. Return values and
 * possible exceptions are copied over the network. RMI errors are signaled
 * with RemoteExceptions.
