Consumers and Suppliers

[Vitaly Davidovich]

I'm with David on this one.  It's not that a queue is both at same time,
but rather it's neither - it's just a handoff/communication channel between
producers/consumers.

I'd say a queue can be a message sink (receives) and message source
(returns), but supplier/consumer is too close of a name to what people
typically think of in that case, and it's not the queue.

My $.02

I didn't mean that the collection was typically simultaneously a Consumer
and a Supplier, I meant that it was typically one or the other (I should
have been clearer in what I said). In my own collection library I do this
and I find it very convenient.
