方法详细资料

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.

rebuildSelectors

public void rebuildSelectors()

Replaces the current Selectors of the child event loops with newly created Selectors to work around the infamous epoll 100% CPU bug.

newChild

protected EventLoop newChild(java.util.concurrent.Executor executor,
                             java.lang.Object... args)
                      throws java.lang.Exception

从类复制的说明: MultithreadEventExecutorGroup

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

指定者:

newChild 在类中 MultithreadEventLoopGroup

抛出:

java.lang.Exception
