Field Details

KEY_MAX_THREADS

static final String KEY_MAX_THREADS

Key to setting the maximum number of computation scheduler threads. Zero or less is interpreted as use available. Capped by available.

MAX_THREADS

static final int MAX_THREADS

The maximum number of computation scheduler threads.

SHUTDOWN_WORKER

static final EventLoopsScheduler.PoolWorker SHUTDOWN_WORKER

NONE

static final EventLoopsScheduler.FixedSchedulerPool NONE

This will indicate no pool is active.

Constructor Details

EventLoopsScheduler

public EventLoopsScheduler(ThreadFactory threadFactory)

Create a scheduler with pool size equal to the available processor count and using least-recent worker selection policy.

Parameters:

threadFactory - the factory to use with the executors

Method Details

createWorker

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 Subscription.unsubscribe().

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

start

public void start()

Description copied from interface: SchedulerLifecycle

Allows the Scheduler instance to start threads and accept tasks on them.

Implementations should make sure the call is idempotent and threadsafe.

Specified by:

start in interface SchedulerLifecycle

shutdown

public void shutdown()

Description copied from interface: SchedulerLifecycle

Instructs the Scheduler instance to stop threads and stop accepting tasks on any outstanding Workers.

Implementations should make sure the call is idempotent and threadsafe.

Specified by:

shutdown in interface SchedulerLifecycle

scheduleDirect

public Subscription scheduleDirect(Action0 action)

Schedules the action directly on one of the event loop workers without the additional infrastructure and checking.

Parameters:

action - the action to schedule

Returns:

the subscription
