### Tags mittels Enumeration

Wenn Sie eine große Anwendung haben, können sich am Ende **viele Tags** anhäufen, und Sie möchten sicherstellen, dass Sie für verwandte *Pfadoperationen* immer den **gleichen Tag** nehmen.

In diesem Fall macht es Sinn, die Tags in einem `Enum` zu speichern.

                    String.format(
                            "Timing attack vulnerability detected: timing ratio %.3f exceeds tolerance %.3f "
                                    + "(start: %d ns, middle: %d ns, end: %d ns)",
                            timingRatio, TIMING_TOLERANCE, timeStart, timeMiddle, timeEnd));
        } finally {
            // Clean up resources
            baseAuth.close();
            startAuth.close();

        operation -->> dep: Raise Exception (e.g. HTTPException)
        opt handle
            dep -->> dep: Can catch exception, raise a new HTTPException, raise other exception
        end
        handler -->> client: HTTP error response
    end

    operation ->> client: Return response to client
