封闭类:
ChannelSendOperator<T>
private class ChannelSendOperator.WriteBarrier extends Object implements reactor.core.CoreSubscriber<T>, org.reactivestreams.Subscription, org.reactivestreams.Publisher<T>
A barrier inserted between the write source and the write subscriber (i.e. the HTTP server adapter) that pre-fetches and waits for the first signal before deciding whether to hook in to the write subscriber.

Acts as:

  • Subscriber to the write source.
  • Subscription to the write subscriber.
  • Publisher to the write subscriber.

Also uses ChannelSendOperator<T>.WriteCompletionBarrier to communicate completion and detect cancel signals from the completion subscriber.
