Interface Scheduler

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface Scheduler

A source of delays useful for scheduling message delivery in tests.

Method Summary

Modifier and Type	Method	Description
static Scheduler	defaultScheduler()	Returns a scheduler that delays messages by a random amount between 80ms and 120ms.
static Scheduler	defaultScheduler(Random rand)	Returns a scheduler that delays messages by a random amount between 80ms and 120ms using the given random number generator.
static Scheduler	randomScheduler(Random rand, long base, long jitter)	Returns a scheduler that delays messages by a random amount between base and base + jitter at millisecond precision using the given random number generator.
Duration	schedule()	Returns the delay until the value should be scheduled.
