org.springframework.cloud.stream.binder.kafka.streams.KafkaStreamsMessageConversionDelegate

public class KafkaStreamsMessageConversionDelegate
extends Object

Delegate for handling all framework level message conversions inbound and outbound on KStream. If native encoding is not enabled, then serialization will be performed on outbound messages based on a contentType. Similarly, if native decoding is not enabled, deserialization will be performed on inbound messages based on a contentType. Based on the contentType, a MessageConverter will be resolved.
