Class JacksonProcessor

java.lang.Object
io.micronaut.core.async.subscriber.SingleThreadedBufferingSubscriber<R>
io.micronaut.core.async.processor.SingleThreadedBufferingProcessor<byte[],com.fasterxml.jackson.databind.JsonNode>
io.micronaut.jackson.parser.JacksonProcessor
All Implemented Interfaces:
io.micronaut.core.async.subscriber.Completable, io.micronaut.core.async.subscriber.Emitter<byte[]>, org.reactivestreams.Processor<byte[],com.fasterxml.jackson.databind.JsonNode>, org.reactivestreams.Publisher<com.fasterxml.jackson.databind.JsonNode>, org.reactivestreams.Subscriber<byte[]>
public class JacksonProcessor extends io.micronaut.core.async.processor.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
