BlockingQueue

[Foxhunter]

Is there anything like a Java BlockingQueue in the POCO libraries? I know it's not a difficult thing to create and POCO's mantra is not to reinvent the wheel, but this structure comes up a lot and I've noticed that Boost never really added it.

There's Poco::NotificationQueue which has a blocking dequeue operation (with optional timeout) that waits until there's something to dequeue. The other half of BlockingQueue, a blocking enqueue operation if the queue is too large, can be implemented by creating a class that combines a Poco::NotificationQueue and a Poco::Semaphore.
