shutdownGracefully	back to summary
public Future<?> shutdownGracefully(long quietPeriod, long timeout, TimeUnit unit) Implements io.netty.util.concurrent.EventExecutorGroup.shutdownGracefully. Doc from io.netty.util.concurrent.EventExecutorGroup.shutdownGracefully. Signals this executor that the caller wants the executor to be shut down. Once this method is called, `isShuttingDown()` starts to return `true`, and the executor prepares to shut itself down. Unlike `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:long the quiet period as described in the documentation timeout:long the maximum amount of time to wait until the executor is shutdown() regardless if a task was submitted during the quiet period unit:TimeUnit the unit of `quietPeriod` and `timeout` Returns:Future<?> the `terminationFuture()` Annotations @Override
