Class Timings

java.lang.Object

io.github.wysohn.triggerreactor.tools.timings.Timings

public class Timings
extends Object

A Benchmark system to measure runtime of various tasks throughout the Triggers deployed by users.

This class is inspired by how java.util.logging.Logger works, where Logger.getLogger(String) either create new Logger or get the existing Logger, and the '.'(dot) in the name indicating the hierarchy of the Loggers. For example, Timings.getTiming("my.timing.name") would yield three level of hierarchy: 'my', 'timing', and 'name', and 'timing' would be the child of 'my' and 'name' would be child of 'timing.'
