Class DaqScalersSequence

java.lang.Object

org.jlab.detector.scalers.DaqScalersSequence

All Implemented Interfaces:

Comparator<DaqScalers>

public class DaqScalersSequence
extends Object
implements Comparator<DaqScalers>

For easy access to most recent scaler readout for any given event. See the main() method for example use case, where only the 2 lines marked with "!!!" are specific to accessing scalers.
