@FunctionalInterface public static interface MatsEndpoint.ProcessSingleLambda<R,I>
ProcessLambdawhich does not have a state, and have the same return-semantics as
ProcessReturnLambda- used for single-stage endpoints as these does not have multiple stages to transfer state between. However, since it is possible to send state along with the request, one may still use the
ProcessReturnLambdafor single-stage endpoints, but in this case you need to code it up yourself by making a multi-stage and then just adding a single lastStage.
