构造器详细资料

NioEventLoopGroup

public NioEventLoopGroup()

Create a new instance using the default number of threads, the default ThreadFactory and the SelectorProvider which is returned by SelectorProvider.provider().

NioEventLoopGroup

public NioEventLoopGroup(int nThreads)

Create a new instance using the specified number of threads, ThreadFactory and the SelectorProvider which is returned by SelectorProvider.provider().

NioEventLoopGroup

public NioEventLoopGroup(int nThreads,
                 java.util.concurrent.ThreadFactory threadFactory)

Create a new instance using the specified number of threads, the given ThreadFactory and the SelectorProvider which is returned by SelectorProvider.provider().

NioEventLoopGroup

public NioEventLoopGroup(int nThreads,
                 java.util.concurrent.ThreadFactory threadFactory,
                 java.nio.channels.spi.SelectorProvider selectorProvider)

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

NioEventLoopGroup

public NioEventLoopGroup(int nThreads,
                 java.util.concurrent.ThreadFactory threadFactory,
                 java.nio.channels.spi.SelectorProvider selectorProvider,
                 SelectStrategyFactory selectStrategyFactory)

NioEventLoopGroup

public NioEventLoopGroup(int nThreads,
                 java.util.concurrent.ThreadFactory threadFactory,
                 java.nio.channels.spi.SelectorProvider selectorProvider,

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 EventExecutor newChild(java.util.concurrent.ThreadFactory threadFactory,
                     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 MultithreadEventExecutorGroup

抛出:

java.lang.Exception
