public enum ChannelState extends Enum<ChannelState>
The current or future state of aChannel.The state of a
Channelis interpreted differently depending on the value of aChannelStateEventand the direction of the event in aChannelPipeline:Direction State Value Meaning Upstream OPENtrueThe channel is open. Upstream OPENfalseThe channel is closed. Upstream BOUNDSocketAddressThe channel is bound to a local address. Upstream BOUNDnullThe channel is unbound to a local address. Upstream CONNECTEDSocketAddressThe channel is connected to a remote address. Upstream CONNECTEDnullThe channel is disconnected from a remote address. Upstream INTEREST_OPSan integer The channel interestOps has been changed. Downstream OPENtrueN/A Downstream OPENfalseClose the channel. Downstream BOUNDSocketAddressBind the channel to the specified local address. Downstream BOUNDnullUnbind the channel from the current local address. Downstream CONNECTEDSocketAddressConnect the channel to the specified remote address. Downstream CONNECTEDnullDisconnect the channel from the current remote address. Downstream INTEREST_OPSan integer Change the interestOps of the channel. To see how an event is interpreted further, please refer to
