Class UnorderedThreadPoolEventExecutor

java.lang.Object

java.util.concurrent.AbstractExecutorService

java.util.concurrent.ThreadPoolExecutor

java.util.concurrent.ScheduledThreadPoolExecutor

io.netty.util.concurrent.UnorderedThreadPoolEventExecutor

All Implemented Interfaces:

EventExecutor, EventExecutorGroup, ThreadAwareExecutor, Iterable<EventExecutor>, Executor, ExecutorService, ScheduledExecutorService

@Deprecated
public final class UnorderedThreadPoolEventExecutor
extends ScheduledThreadPoolExecutor
implements EventExecutor

Deprecated.

The behavior of this event executor deviates from the typical Netty execution model and can cause subtle issues as a result. Applications that wish to process messages with greater parallelism, should instead do explicit off-loading to their own thread-pools.

EventExecutor implementation which makes no guarantees about the ordering of task execution that are submitted because there may be multiple threads executing these tasks. This implementation is most useful for protocols that do not need strict ordering.

Because it provides no ordering, care should be taken when using it!

Method Details

next

public EventExecutor next()

Deprecated.

Description copied from interface: EventExecutorGroup

Returns one of the EventExecutors managed by this EventExecutorGroup.

Specified by:

next in interface EventExecutorGroup

parent

public EventExecutorGroup parent()

Deprecated.

Description copied from interface: EventExecutor

Return the EventExecutorGroup which is the parent of this EventExecutor,

Specified by:

parent in interface EventExecutor

inEventLoop

public boolean inEventLoop()

Deprecated.

Description copied from interface: EventExecutor

Calls EventExecutor.inEventLoop(Thread) with Thread.currentThread() as argument

Specified by:

inEventLoop in interface EventExecutor

inEventLoop

public boolean inEventLoop(Thread thread)

Deprecated.

Description copied from interface: EventExecutor

Return true if the given Thread is executed in the event loop, false otherwise.

Specified by:

inEventLoop in interface EventExecutor

newPromise

public <V> Promise<V> newPromise()

Deprecated.

Description copied from interface: EventExecutor

public <V> ProgressivePromise<V> newProgressivePromise()

Deprecated.

Description copied from interface: EventExecutor

Create a new ProgressivePromise.

Specified by:

newProgressivePromise in interface EventExecutor

newSucceededFuture

public <V> Future<V> newSucceededFuture(V result)

Deprecated.

Description copied from interface: EventExecutor

Create a new Future which is marked as succeeded already. So Future.isSuccess() will return true. All FutureListener added to it will be notified directly. Also every call of blocking methods will just return without blocking.

Specified by:

newSucceededFuture in interface EventExecutor

newFailedFuture

public <V> Future<V> newFailedFuture(Throwable cause)

Deprecated.

Description copied from interface: EventExecutor

Create a new Future which is marked as failed already. So Future.isSuccess() will return false. All FutureListener added to it will be notified directly. Also every call of blocking methods will just return without blocking.

Specified by:

isShuttingDown

public boolean isShuttingDown()

Deprecated.

Description copied from interface: EventExecutorGroup

Returns true if and only if all EventExecutors managed by this EventExecutorGroup are being shut down gracefully or was shut down.

Specified by:

isShuttingDown in interface EventExecutorGroup

shutdownNow

public List<Runnable> shutdownNow()

Deprecated.

Specified by:

shutdownNow in interface EventExecutorGroup

Specified by:

shutdown

public void shutdown()

Deprecated.

Specified by:

shutdownGracefully

public Future<?> shutdownGracefully()

Deprecated.

Description copied from interface: EventExecutorGroup

Shortcut method for EventExecutorGroup.shutdownGracefully(long, long, TimeUnit) with sensible default values.

Specified by:

shutdownGracefully in interface EventExecutorGroup

Returns:

the EventExecutorGroup.terminationFuture()

shutdownGracefully

public Future<?> shutdownGracefully(long quietPeriod,
 long timeout,
 TimeUnit unit)

Deprecated.

Description copied from interface: EventExecutorGroup

Signals this executor that the caller wants the executor to be shut down. Once this method is called, EventExecutorGroup.isShuttingDown() starts to return true, and the executor prepares to shut itself down. Unlike EventExecutorGroup.shutdown(), graceful shutdown ensures that no tasks are submitted for 'the quiet period' (usually a couple seconds) before it shuts itself down. If a task is submitted during the quiet period, it is guaranteed to be accepted and the quiet period will start over.

Specified by:

shutdownGracefully in interface EventExecutorGroup

Parameters:

quietPeriod - the quiet period as described in the documentation

timeout - the maximum amount of time to wait until the executor is EventExecutorGroup.shutdown() regardless if a task was submitted during the quiet period

unit - the unit of quietPeriod and timeout

Returns:

the EventExecutorGroup.terminationFuture()
