Interface StatisticsCalculator

All Superinterfaces:

Serializable

All Known Implementing Classes:

LongAdderStatisticsCalculator, NullStatisticsCalculator, StandardStatisticsCalculator

public interface StatisticsCalculator
extends Serializable

The StatisticsCalculator interface contains methods for easy statistics management. There are three types of methods: First the incrementX() methods that increase the corresponding counter. Second, the getX() methods that return the raw statistic counts. Third, the tick() method, that returns the count difference between the last tick and the current tick.
