Examples of ChannelStateEvent

com.facebook.presto.jdbc.internal.netty.channel.ChannelStateEvent
A {@link ChannelEvent} which represents the change of the {@link Channel}state. It can mean the notification of a change or the request for a change, depending on whether it is an upstream event or a downstream event respectively. Please refer to the {@link ChannelEvent} documentation tofind out what an upstream event and a downstream event are and what fundamental differences they have. @apiviz.has com.facebook.presto.jdbc.internal.netty.channel.ChannelState
