extends Object

This class is a container of queues that allows to select a queue in a round robin fashion, considering priority of the queue. the quantum is just how many poll() will return the same object. e.g. if quantum is 1 and you have A and B as object you'll get: A B A B e.g. if quantum is 2 and you have A and B as object you'll get: A A B B A A B B then the object priority is just a priority * quantum Example: - three queues (A, B, C) with priorities (1, 1, 2) - The first poll() will return A - The second poll() will return B - The third and forth poll() will return C - and so on again and again.
