extends Object

java.lang.Object
jdk.jfr.internal.periodic.Batch

Imports

java.util.ArrayList, .List

Class that holds periodic tasks that run at the same time.

For example, events with period 1s, 3s and 7s can run when the 1s event run, not every time, but some of the time. An event with period 1.5s would not belong to the same batch since it would need to run between the 1s interval.

This class should only be accessed from the periodic task thread.
