public final class EpollEventLoopGroup
extends io.netty.channel.MultithreadEventLoopGroup

EventLoopGroup which uses epoll under the covers. Because of this it only works on linux.

Constructor Detail

EpollEventLoopGroup

public EpollEventLoopGroup()

Create a new instance using the default number of threads and the default ThreadFactory.

EpollEventLoopGroup

public EpollEventLoopGroup(int nThreads)

Create a new instance using the specified number of threads and the default ThreadFactory.

EpollEventLoopGroup

public EpollEventLoopGroup(int nThreads,
                   ThreadFactory threadFactory)

Create a new instance using the specified number of threads and the given ThreadFactory.

EpollEventLoopGroup

@Deprecated
public EpollEventLoopGroup(int nThreads,
                              ThreadFactory threadFactory,
                              int maxEventsAtOnce)

Deprecated. Use EpollEventLoopGroup(int), EpollEventLoopGroup(int) or EpollEventLoopGroup(int, ThreadFactory)

Create a new instance using the specified number of threads, the given ThreadFactory and the given maximal amount of epoll events to handle per epollWait(...).

Method Detail

setIoRatio

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.

newChild

protected io.netty.channel.EventLoop newChild(Executor executor,
                                  Object... args)
                                       throws Exception

Overrides:

newChild in class io.netty.channel.MultithreadEventLoopGroup

Throws:

Exception
