Interface MessageTranslator<P extends Message<?>>

  • Type Parameters:
    P - The type of the translated message's payload
    All Superinterfaces:
    java.util.function.Function<Message<?>,​P>
    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.
