1.59 +/**
1.60 + *
1.61 + * <p>
1.62 + * This class mainly performs the following two tasks:
1.63 + * <ol>
1.64 + * <li>Takes a {@link Message} that represents a request,
1.65 + * and extracts the arguments (and updates {@link Holder}s.)
1.66 + * <li>Accepts return value and {@link Holder} arguments for a Java method,
1.67 + * and creates {@link JAXBMessage} that represents a response message.
1.68 + * </ol>
1.69 + *
1.70 + * <h2>Creating {@link JAXBMessage}</h2>
1.71 + * <p>
1.72 + * At the construction time, we prepare {@link EndpointArgumentsBuilder} that knows how to create endpoint {@link Method}
1.73 + * invocation arguments.
1.74 + * we also prepare {@link EndpointResponseMessageBuilder} and {@link MessageFiller}s
1.75 + * that know how to move arguments into a {@link Message}.
1.76 + * Some arguments go to the payload, some go to headers, still others go to attachments.
