register

public ChannelFuture register(Channel channel)

从接口复制的说明: EventLoopGroup

Register a Channel with this EventLoop. The returned ChannelFuture will get notified once the registration was complete.

指定者:

register 在接口中 EventLoopGroup

register

public ChannelFuture register(ChannelPromise promise)

从接口复制的说明: EventLoopGroup

Register a Channel with this EventLoop using a ChannelFuture. The passed ChannelFuture will get notified once the registration was complete and also will get returned.

指定者:

register 在接口中 EventLoopGroup

register

@Deprecated
public ChannelFuture register(Channel channel,
                                           ChannelPromise promise)

已过时。

从接口复制的说明: EventLoopGroup

指定者:

register 在接口中 EventLoopGroup

executeAfterEventLoopIteration

@UnstableApi
public final void executeAfterEventLoopIteration(java.lang.Runnable task)

Adds a task to be run once at the end of next (or current) eventloop iteration.

参数:

task - to be added.

afterRunningAllTasks

protected void afterRunningAllTasks()

从类复制的说明: SingleThreadEventExecutor

Invoked before returning from SingleThreadEventExecutor.runAllTasks() and SingleThreadEventExecutor.runAllTasks(long).

覆盖:

afterRunningAllTasks 在类中 SingleThreadEventExecutor

hasTasks

protected boolean hasTasks()

覆盖:

hasTasks 在类中 SingleThreadEventExecutor

另请参阅:

Collection.isEmpty()

pendingTasks

public int pendingTasks()

从类复制的说明: SingleThreadEventExecutor

Return the number of tasks that are pending for processing.

覆盖:

pendingTasks 在类中 SingleThreadEventExecutor

registeredChannels

@UnstableApi
public int registeredChannels()

Returns the number of Channels registered with this EventLoop or -1 if operation is not supported. The returned value is not guaranteed to be exact accurate and should be viewed as a best effort.

registeredChannelsIterator

@UnstableApi
public java.util.Iterator<Channel> registeredChannelsIterator()

返回:

read-only iterator of active Channels registered with this EventLoop. The returned value is not guaranteed to be exact accurate and should be viewed as a best effort. This method is expected to be called from within event loop.

抛出:

java.lang.UnsupportedOperationException - if operation is not supported by implementation.
