/**
 * Adapter that supports endpoint methods with message contexts. Supports methods with the following signature:
 * <pre>
 * void handleMyMessage(MessageContext request);
 * </pre>
 * I.e. methods that take a single {@link MessageContext} parameter, and return {@code void}. The method can have
 * any name, as long as it is mapped by an {@link org.springframework.ws.server.EndpointMapping}.
 *
 * <p>This adapter is registered by default by the {@link MessageDispatcher} and {@link SoapMessageDispatcher}.
