Method Detail

run

public void run()

This method updates the QueueSizeMovingAverageTask for each ResourceQueue each time it is run.

Note: This is written so as to not cause hard references to be retained to the ResourceQueues. The QueueSizeMovingAverageTask is a member field for the ResourceQueue for the same reason. This way the statistics for active ResourceQueues are tracked and may be reported but ResourceQueues will remain strongly reachable only if there are tasks holding their locks.
