NonStickyOrderedEventExecutor(EventExecutor executor,
 int maxTaskExecutePerRun)

Method Details

run

public void run()

Specified by:

run in interface Runnable

inEventLoop

public boolean inEventLoop(Thread thread)

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

isShuttingDown

public boolean isShuttingDown()

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

shutdownGracefully

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

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()

terminationFuture

public Future<?> terminationFuture()

Description copied from interface: EventExecutorGroup

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

Specified by:

terminationFuture in interface EventExecutorGroup

shutdown

public void shutdown()

Specified by:

shutdown in interface EventExecutorGroup

Specified by:

shutdown in interface ExecutorService

Specified by:

shutdown in class AbstractEventExecutor

isShutdown

public boolean isShutdown()

Specified by:

isShutdown in interface ExecutorService

isTerminated

public boolean isTerminated()

Specified by:

isTerminated in interface ExecutorService

awaitTermination

public boolean awaitTermination(long timeout,
 TimeUnit unit)
                         throws InterruptedException

Specified by:

awaitTermination in interface ExecutorService

Throws:

InterruptedException

execute

public void execute(Runnable command)

Specified by:

execute in interface Executor
