public interface IHandlerInvocation<HANDLER,MESSAGE>
extends ISubscriptionContextAware

A handler invocation encapsulates the logic that is used to invoke a single message handler to process a given message. A handler invocation might come in different flavours and can be composed of various independent invocations by means of delegation (-> decorator pattern) If an exception is thrown during handler invocation it is wrapped and propagated as a publication error
