Chen commented on COLLECTIONS-735:
----------------------------------
David Mollitor, Varun Vats :
I have created TransformedDeque, BlockingDeque, CircularDeque,
PredicatedDeque and SynchronizedDeque for deque interface(see
https://github.com/apache/commons-collections/pull/111), I think combine
CircularDeque and BlockingDeque will make a concurrent CircularFifoQueue. I
don't konw if there is a better way to complete it . It would be great if you
could review my PR and give some advice.

> Create a {{CircularFifoQueue}} that is also a {{BlockingQueue}}.
> That is to say, if the queue is full, overwrite the oldest element. If the
> queue is empty, the reader blocks until a value becomes available.
