Class TextMessageTranslator

de.otto.synapse.translator.TextMessageTranslator

All Implemented Interfaces:

MessageTranslator<TextMessage>, java.util.function.Function<Message<?>,TextMessage>

public class TextMessageTranslator
extends java.lang.Object
implements MessageTranslator<TextMessage>

A MessageTranslator that converts messages into TextMessage.

The Message Translator is the messaging equivalent of the Adapter pattern described in [GoF]. An adapter converts the interface of a component into a another interface so it can be used in a different context.

This implementation is relying on ObjectMappers.currentObjectMapper() to transform message payloads with non-String payload into a JSON payload.
