public final class EpollEventLoopGroup extends MultithreadEventLoopGroup
MultithreadEventLoopGroup
which uses epoll under the
covers. This EventLoopGroup
works only on Linux systems!Constructor and Description |

Executor . |

protected EventLoop |
newChild(Executor executor,
Object... args)
Create a new EventExecutor which will later then accessible via the
MultithreadEventExecutorGroup.next() method. |
void |
setIoRatio(int ioRatio)
Sets the percentage of the desired amount of time spent for I/O in the child event loops.
