所有已实现的接口:

EventExecutor, EventExecutorGroup, OrderedEventExecutor, java.lang.Iterable<EventExecutor>, java.util.concurrent.Executor, java.util.concurrent.ExecutorService, java.util.concurrent.ScheduledExecutorService

public final class GlobalEventExecutor
extends AbstractScheduledEventExecutor
implements OrderedEventExecutor

Single-thread singleton EventExecutor. It starts the thread automatically and stops it when there is no task pending in the task queue for io.netty.globalEventExecutor.quietPeriodSeconds second (default is 1 second). Please note it is not scalable to schedule large number of tasks to this executor; use a dedicated executor.

INSTANCE

public static final GlobalEventExecutor INSTANCE

方法详细资料

pendingTasks

public int pendingTasks()

Return the number of tasks that are pending for processing.

inEventLoop

public boolean inEventLoop(java.lang.Thread thread)

从接口复制的说明: EventExecutor

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

指定者:

inEventLoop 在接口中 EventExecutor

shutdownGracefully

public Future<?> shutdownGracefully(long quietPeriod,
                                    long timeout,
                                    java.util.concurrent.TimeUnit unit)

从接口复制的说明: 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.

指定者:

shutdownGracefully 在接口中 EventExecutorGroup

参数:

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

返回:

the EventExecutorGroup.terminationFuture()

terminationFuture

public Future<?> terminationFuture()

从接口复制的说明: EventExecutorGroup

Returns the Future which is notified when all EventExecutors managed by this EventExecutorGroup have been terminated.

指定者:

terminationFuture 在接口中 EventExecutorGroup

shutdown

@Deprecated
public void shutdown()

已过时。

指定者:

shutdown 在接口中 EventExecutorGroup

指定者:

shutdown 在接口中 java.util.concurrent.ExecutorService

指定者:

shutdown 在类中 AbstractEventExecutor

isShuttingDown

public boolean isShuttingDown()

从接口复制的说明: EventExecutorGroup

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

指定者:

isShuttingDown 在接口中 EventExecutorGroup

isShutdown

public boolean isShutdown()

指定者:

isShutdown 在接口中 java.util.concurrent.ExecutorService

isTerminated

public boolean isTerminated()

指定者:

isTerminated 在接口中 java.util.concurrent.ExecutorService

awaitTermination

public boolean awaitTermination(long timeout,
                                java.util.concurrent.TimeUnit unit)

指定者:

awaitTermination 在接口中 java.util.concurrent.ExecutorService

awaitInactivity

public boolean awaitInactivity(long timeout,
                               java.util.concurrent.TimeUnit unit)
                        throws java.lang.InterruptedException

Waits until the worker thread of this executor has no tasks left in its task queue and terminates itself. Because a new worker thread will be started again when a new task is submitted, this operation is only useful when you want to ensure that the worker thread is terminated after your application is shut down and there's no chance of submitting a new task afterwards.

返回:

true if and only if the worker thread has been terminated

抛出:

java.lang.InterruptedException

execute

public void execute(java.lang.Runnable task)

指定者:

execute 在接口中 java.util.concurrent.Executor
