Class ImmediateEventExecutor

io.netty.util.concurrent.ImmediateEventExecutor

All Implemented Interfaces:: EventExecutor, EventExecutorGroup, ThreadAwareExecutor, Iterable<EventExecutor>, Executor, ExecutorService, ScheduledExecutorService

public final class ImmediateEventExecutor extends AbstractEventExecutor

Executes Runnable objects in the caller's thread. If the execute(Runnable) is reentrant it will be queued until the original Runnable finishes execution.

All Throwable objects thrown from execute(Runnable) will be swallowed and logged. This is to ensure that all queued Runnable objects have the chance to be run.

Method Details
- inEventLoop
  
  public boolean inEventLoop()
  
  Description copied from interface: EventExecutor
  
  Calls EventExecutor.inEventLoop(Thread) with Thread.currentThread() as argument
- 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.
- 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.
  
  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.
- shutdown
  
  @Deprecated public void shutdown()
  
  Deprecated.
