public class QueueLimitCalculator
extends java.lang.Object

This class interacts with the NodeQueueLoadMonitor to keep track of the mean and standard deviation of the configured metrics (queue length or queue wait time) used to characterize the queue load of a specific node. The NodeQueueLoadMonitor triggers an update (by calling the update() method) every time it performs a re-ordering of all nodes.
