register

public ChannelFuture register(Channel channel)

Description copied from interface: EventLoopGroup

Register a Channel with an EventLoop from this EventLoopGroup. The returned ChannelFuture will get notified once the registration is completed.

It's only safe to submit a new task to the EventLoop from within a ChannelHandler once the ChannelPromise succeeded. Otherwise the task may or may not be rejected.

Specified by:

register in interface EventLoopGroup

register

public ChannelFuture register(Channel channel,
                     ChannelPromise promise)

Description copied from interface: EventLoopGroup

Register a Channel with an EventLoop from this EventLoopGroup. The provided ChannelPromise will get notified once the registration is completed. The returned ChannelFuture is the same ChannelPromise that was passed to the method.

It's only safe to submit a new task to the EventLoop from within a ChannelHandler once the ChannelPromise succeeded. Otherwise the task may or may not be rejected.

Specified by:

register in interface EventLoopGroup
