-/**
- * BlockingMethodFrameListener is a 'rendezvous' which acts as a {@link AMQMethodListener} that delegates handling of
- * incoming methods to a method listener implemented as a sub-class of this and hands off the processed method or
- * error to a consumer. The producer of the event does not have to wait for the consumer to take the event, so this
- * differs from a 'rendezvous' in that sense.
- *
- * <p/>BlockingMethodFrameListeners are used to coordinate waiting for replies to method calls that expect a response.
- * They are always used in a 'one-shot' manner, that is, to recieve just one response. Usually the caller has to register
- * them as method listeners with an event dispatcher and remember to de-register them (in a finally block) once they
- * have been completed.
- *
- * <p/>The {@link #processMethod} must return <tt>true</tt> on any incoming method that it handles. This indicates to
- * this listeners that the method it is waiting for has arrived. Incoming methods are also filtered by channel prior to
- * being passed to the {@link #processMethod} method, so responses are only received for a particular channel. The
- * channel id must be passed to the constructor.
- *
- * <p/>Errors from the producer are rethrown to the consumer.
- *

- * @todo Might be neater if this method listener simply wrapped another that provided the method handling using a
- * methodRecevied method. The processMethod takes an additional channelId, however none of the implementations
- * seem to use it. So wrapping the listeners is possible.
- * @todo If the retrotranslator can handle it, could use a SynchronousQueue to implement this rendezvous. Need to
- * check that SynchronousQueue has a non-blocking put method available.
