Class ImmediateThinScheduler

java.lang.Object
io.reactivex.rxjava3.core.Scheduler
io.reactivex.rxjava3.internal.schedulers.ImmediateThinScheduler
public final class ImmediateThinScheduler extends Scheduler
A Scheduler partially implementing the API by allowing only non-delayed, non-periodic task execution on the current thread immediately.

Note that this doesn't support recursive scheduling and disposing the returned Disposable has no effect (because when the schedule() method returns, the task has been already run).

  • Field Details

      public static final Scheduler INSTANCE
      The singleton instance of the immediate (thin) scheduler.

    • scheduleDirect

      @NonNull public @NonNull Disposable scheduleDirect(@NonNull @NonNull Runnable run)
      Description copied from class: Scheduler
      Schedules the given task on this Scheduler without any time delay.

      This method is safe to be called from multiple threads but there are no ordering or non-overlapping guarantees between tasks.

      Overrides:
      scheduleDirect in class Scheduler
      Parameters:
      run - the task to execute
      Returns:
      the Disposable instance that let's one cancel this particular task.

    • scheduleDirect

      @NonNull public @NonNull Disposable scheduleDirect(@NonNull @NonNull Runnable run, long delay, TimeUnit unit)
      Description copied from class: Scheduler
      Schedules the execution of the given task with the given time delay.

      This method is safe to be called from multiple threads but there are no ordering guarantees between tasks.

      Overrides:
      scheduleDirect in class Scheduler
      Parameters:
      run - the task to schedule
      delay - the delay amount, non-positive values indicate non-delayed scheduling
      unit - the unit of measure of the delay amount
      Returns:
      the Disposable that let's one cancel this particular delayed task.

    • schedulePeriodicallyDirect

      @NonNull public @NonNull Disposable schedulePeriodicallyDirect(@NonNull @NonNull Runnable run, long initialDelay, long period, TimeUnit unit)
      Description copied from class: Scheduler
      Schedules a periodic execution of the given task with the given initial time delay and repeat period.

      This method is safe to be called from multiple threads but there are no ordering guarantees between tasks.

      The periodic execution is at a fixed rate, that is, the first execution will be after the initialDelay, the second after initialDelay + period, the third after initialDelay + 2 * period, and so on.

      Overrides:
      schedulePeriodicallyDirect in class Scheduler
      Parameters:
      run - the task to schedule
      initialDelay - the initial delay amount, non-positive values indicate non-delayed scheduling
      period - the period at which the task should be re-executed
      unit - the unit of measure of the delay amount
      Returns:
      the Disposable that let's one cancel this particular delayed task.

    • createWorker

      @NonNull public @NonNull Scheduler.Worker createWorker()
      Description copied from class: Scheduler
      Retrieves or creates a new Scheduler.Worker that represents sequential execution of actions.

      When work is completed, the Worker instance should be released by calling Disposable.dispose() to avoid potential resource leaks in the underlying task-execution scheme.

      Work on a Scheduler.Worker is guaranteed to be sequential and non-overlapping.

      Specified by:
      createWorker in class Scheduler
      Returns:
      a Worker representing a serial queue of actions to be executed
