public function QueueInterface::numberOfItems

Retrieves the number of items in the queue.

This is intended to provide a "best guess" count of the number of items in the queue. Depending on the implementation and the setup, the accuracy of the results of this function may vary.

e.g. On a busy system with a large number of consumers and items, the result might only be valid for a fraction of a second and not provide an accurate representation.

Return value

An integer estimate of the number of items in the queue.
