Interface RateTracker

All Known Implementing Classes:

ThreadSafeRateTracker

public interface RateTracker

Describes an object that tracks occurrences of a single event to compute the average rate over periods of time. The rate of occurrences is simply the number of times that the track method has been called since the last time the period was reset (either as part of the call to getRateAndResetPeriod, object instantiation, or some other implementation-specific way of resetting the period) divided by the amount time since that reset.

Method Summary

Modifier and Type	Method and Description
double	getRateAndResetPeriod() Get the rate of events per second based on the data since the last call to this method (or object instantiation, for the first call).
void	track() Record that the tracked even occurred.
