Package akka.actor

Class LightArrayRevolverScheduler

java.lang.Object

akka.actor.LightArrayRevolverScheduler

All Implemented Interfaces:

Scheduler, java.io.Closeable, java.lang.AutoCloseable

public class LightArrayRevolverScheduler
extends java.lang.Object
implements Scheduler, java.io.Closeable

Clock implementation is replaceable (for testing); the implementation must return a monotonically increasing series of Long nanoseconds.

schedule

public Cancellable schedule(scala.concurrent.duration.FiniteDuration initialDelay,
                            scala.concurrent.duration.FiniteDuration delay,
                            java.lang.Runnable runnable,
                            scala.concurrent.ExecutionContext executor)

Description copied from interface: Scheduler

Schedules a Runnable to be run repeatedly with an initial delay and a frequency. E.g. if you would like the function to be run after 2 seconds and thereafter every 100ms you would set delay = Duration(2, TimeUnit.SECONDS) and interval = Duration(100, TimeUnit.MILLISECONDS). If the execution of the runnable takes longer than the interval, the subsequent execution will start immediately after the prior one completes (there will be no overlap of executions of the runnable). In such cases, the actual execution interval will differ from the interval passed to this method.

If the Runnable throws an exception the repeated scheduling is aborted, i.e. the function will not be invoked any more.

Specified by:

schedule in interface Scheduler

Parameters:

initialDelay - (undocumented)

delay - (undocumented)

runnable - (undocumented)

executor - (undocumented)

Returns:

(undocumented)

scheduleOnce

public Cancellable scheduleOnce(scala.concurrent.duration.FiniteDuration delay,
                                java.lang.Runnable runnable,
                                scala.concurrent.ExecutionContext executor)

Description copied from interface: Scheduler

Schedules a Runnable to be run once with a delay, i.e. a time period that has to pass before the runnable is executed.

Specified by:

scheduleOnce in interface Scheduler

Parameters:

delay - (undocumented)

runnable - (undocumented)

executor - (undocumented)

Returns:

(undocumented)

close

public void close()

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface java.io.Closeable

maxFrequency

public double maxFrequency()

Description copied from interface: Scheduler

The maximum supported task frequency of this scheduler, i.e. the inverse of the minimum time interval between executions of a recurring task, in Hz.

Specified by:

maxFrequency in interface Scheduler

Returns:

(undocumented)
