org.apache.oozie.util.Instrumentation.Cron

Enclosing class:

Instrumentation

public static class Instrumentation.Cron
extends Object

Cron is a stopwatch that can be started/stopped several times.

This class is not thread safe, it does not need to be.

It keeps track of the total time (first start to last stop) and the running time (total time minus the stopped intervals).

Once a Cron is complete it must be added to the corresponding group/name in a Instrumentation instance.
