public interface IHasProcessState<M>
Interface that can be implemented by Listeners that provide their own management of messages processed and in error. If the status 'inProcess' is specified, it will be used when messages are processed. In case of a rollback of the executing transaction, the status of the message will be reverted to 'available', so that it can be retried.
