public abstract class Consumer<E,P extends Producer<E>>
extends BlockingQueueAccessor<P>

A Consumer is aware of several Producers which can be added via the BlockingQueueAccessor.put(Object), BlockingQueueAccessor.put(Object, long) and BlockingQueueAccessor.putWithTimeout(Object, long) method. It can access it's queued Producers with the corresponding BlockingQueueAccessor.get(), BlockingQueueAccessor.get(long) and BlockingQueueAccessor.getBlockingQueue() method.
TODO MM this has nothing to do especially with searching! Design seems overloaded, use a shared single BlockingQueue for communication between consumer and producer!
