All Implemented Interfaces:

Direct Known Subclasses:

FIFODropTailQueue

public abstract class StdSingleServerQueue
extends SingleServerQueue

StdSingleServerQueue is still an abstract class as it does not define methods ReceiveMessage and HandleEndOfService. It contains statistics measuring server occupancy as well as variables for service time (per length unit) and buffer size which are read as parameters. If UseStatistics is unset the statistic is not used (may be useful to increase performance).
