Spring Framework 6.1.4 · org.springframework.http.server.reactive.ChannelSendOperator

Given a write function that accepts a source Publisher<T> to write with and returns Publisher<Void> for the result, this operator helps to defer the invocation of the write function, until we know if the source publisher will begin publishing without an error. If the first emission is an error, the write function is bypassed, and the error is sent directly through the result publisher. Otherwise, the write function is invoked.

Nested and Inner Type Summary

Modifier and Type	Class and Description
private static enum	ChannelSendOperator.State
private class	ChannelSendOperator.WriteBarrier 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.
private class	ChannelSendOperator.WriteCompletionBarrier We need an extra barrier between the WriteBarrier itself and the actual completion subscriber.
