Detailed Description

The consumer end of a distributed queue.

One or more instances of this class are mapped to the identifier of the QueueMaster registered on another node.

Constructor & Destructor Documentation

CO_API co::QueueSlave::QueueSlave	(	const uint32_t	prefetchMark = `Global::getIAttribute(Global::IATTR_QUEUE_MIN_SIZE)`,
		const uint32_t	prefetchAmount = `Global::getIAttribute(Global::IATTR_QUEUE_REFILL)`
	)

Construct a new queue consumer.

The implementation will prefetch items from the queue master to cache thems locally. The prefetchMark determines when new items are requested, and the prefetchAmount how many items are fetched. Prefetching items hides the network latency by pipelining the network communication with the processing but may introduce imbalance between queue slaves if used aggressively.
