the Executor to use, or null if default one should be used.

chooserFactory:EventExecutorChooserFactory

the EventExecutorChooserFactory to use.

selectStrategyFactory:SelectStrategyFactory

the SelectStrategyFactory to use.

rejectedExecutionHandler:RejectedExecutionHandler

the RejectedExecutionHandler to use.

taskQueueFactory:EventLoopTaskQueueFactory

the EventLoopTaskQueueFactory to use for SingleThreadEventLoop#execute(Runnable), or null if default one should be used.

Method Detail

newChildback to summary
protected EventLoop newChild(Executor executor, Object... args) throws Exception

Implements abstract io.netty.channel.MultithreadEventLoopGroup.newChild.

Doc from io.netty.util.concurrent.MultithreadEventExecutorGroup.newChild.

Create a new EventExecutor which will later then accessible via the next() method. This method will be called for each thread that will serve this MultithreadEventExecutorGroup.

Annotations
@Override
setIoRatioback to summary
public void setIoRatio(int ioRatio)

Sets the percentage of the desired amount of time spent for I/O in the child event loops. The default value is 50, which means the event loop will try to spend the same amount of time for I/O as for non-I/O tasks.
