### Tags with Enums { #tags-with-enums }

If you have a big application, you might end up accumulating **several tags**, and you would want to make sure you always use the **same tag** for related *path operations*.

In these cases, it could make sense to store the tags in an `Enum`.

**FastAPI** supports that the same way as with plain strings:

    public Chars() {
      // elements aren't sorted, to better test SortedSet iteration ordering
      super('b', 'a', 'c', 'd', 'e');
    }
  }

  public static class Enums extends SampleElements<AnEnum> {
    public Enums() {
      // elements aren't sorted, to better test SortedSet iteration ordering
      super(AnEnum.B, AnEnum.A, AnEnum.C, AnEnum.D, AnEnum.E);
    }
  }

### Tags mittels Enumeration { #tags-with-enums }

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** verwenden.

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

**FastAPI** unterstützt das auf die gleiche Weise wie einfache Strings:

### Теги с перечислениями { #tags-with-enums }

Если у вас большое приложение, вы можете прийти к необходимости добавить **несколько тегов**, и возможно, вы захотите убедиться в том, что всегда используете **один и тот же тег** для связанных *операций пути*.

В этих случаях, имеет смысл хранить теги в классе `Enum`.

**FastAPI** поддерживает это так же, как и в случае с обычными строками:

  boolean getIfPresent(int repetitions) {
    boolean retVal = false;
    for (int i = 0; i < repetitions; ++i) {
      retVal &= Enums.getIfPresent(enumType, sampleData[i & 255]).isPresent();
    }
    return retVal;
  }

  private enum SmallEnum {
    X0,
    X1,
    X2
  }

  private enum MediumEnum {
    X0,
    X1,
    X2,
    X3,
    X4,
    X5,
    X6,
    X7,
    X8,
    X9,
