java.lang.Object

io.reactivex.Scheduler

io.reactivex.schedulers.TestScheduler

public final class TestScheduler
extends Scheduler

public TestScheduler()

Method Detail

now

public long now(@NonNull
       java.util.concurrent.TimeUnit unit)

Description copied from class: Scheduler

Returns the 'current time' of the Scheduler in the specified time unit.

Overrides:

now in class Scheduler

Parameters:

unit - the time unit

Returns:

the 'current time'

advanceTimeBy

public void advanceTimeBy(long delayTime,
                 java.util.concurrent.TimeUnit unit)

Moves the Scheduler's clock forward by a specified amount of time.

Parameters:

delayTime - the amount of time to move the Scheduler's clock forward

unit - the units of time that delayTime is expressed in

advanceTimeTo

public void advanceTimeTo(long delayTime,
                 java.util.concurrent.TimeUnit unit)

Moves the Scheduler's clock to a particular moment in time.

Parameters:

delayTime - the point in time to move the Scheduler's clock to

unit - the units of time that delayTime is expressed in

triggerActions

public void triggerActions()

Triggers any actions that have not yet been triggered and that are scheduled to be triggered at or before this Scheduler's present time.

createWorker

@NonNull
public Scheduler.Worker createWorker()

Description copied from class: Scheduler

Retrieves or creates a new Scheduler.Worker that represents serial execution of actions.

When work is completed it should be unsubscribed using Disposable.dispose().

Work on a Scheduler.Worker is guaranteed to be sequential.

Specified by:

createWorker in class Scheduler

Returns:

a Worker representing a serial queue of actions to be executed
