Package com.couchbase.client.core.scheduler

Class SchedulerClock

java.lang.Object

java.time.Clock

com.couchbase.client.core.scheduler.SchedulerClock

public class SchedulerClock
extends Clock

Clock adapter around Scheduler. That adoption gives better integration with Java 8 DateTime API.

This feature may be useful for testing purpose, especially for integration with VirtualTimeScheduler. For example:

     
         VirtualTimeScheduler scheduler = VirtualTimeScheduler.create();
         SchedulerClock clock = SchedulerClock.of(scheduler);

         ZonedDateTime beforeAdvance = ZonedDateTime.now(clock);
         scheduler.advanceTimeBy(Duration.ofSeconds(1));
         ZonedDateTime afterAdvance = ZonedDateTime.now(clock);

         Assert.assertTrue(beforeAdvance.isBefore(afterAdvance));
     
 

Since:

3.1.4

Specified by:

withZone in class Clock

getScheduler

@NonNull
public Scheduler getScheduler()

Return wrapped Scheduler instance

Returns:

Scheduler instance

withScheduler

@NonNull
public SchedulerClock withScheduler(Scheduler scheduler)

Builder method that returns new instance of SchedulerClock which is constructed from old ZoneId and passed Scheduler instance

Returns:

Overrides:

equals in class Clock

hashCode

public int hashCode()

Overrides:

hashCode in class Clock

toString

public String toString()

Overrides:

toString in class Object

Create instance of SchedulerClock from given Scheduler and system default ZoneId.systemDefault()

Parameters:

scheduler - Scheduler instance

Returns:

new SchedulerClock
