public class JacksonProcessor
extends SingleThreadedBufferingProcessor<byte[],com.fasterxml.jackson.databind.JsonNode>

A Reactive streams publisher that publishes a JsonNode once the JSON has been fully consumed. Uses NonBlockingJsonParser internally allowing the parsing of JSON from an incoming stream of bytes in a non-blocking manner
