All Known Implementing Classes:

TextMessageTranslator

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface MessageTranslator<P extends Message<?>>
extends java.util.function.Function<Message<?>,P>

Translates any Message<?> into a Message with payload-type P by translating the message's payload into the specified target-type payload.

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.
