## 3. Witness Architecture

### 3.1 Witness Service Types
```java
public enum WitnessServiceType {
    CLUSTER_WITNESS,     // Cluster-aware witness service
    FILE_SERVER_WITNESS, // Individual file server witness
    SCALE_OUT_WITNESS,   // Scale-out file server witness
    DFS_WITNESS         // DFS namespace witness
}

public enum WitnessVersion {
    VERSION_1(0x00010001),  // Windows Server 2012

### Tags con Enums

Si tienes una gran aplicación, podrías terminar acumulando **varias tags**, y querrías asegurarte de que siempre uses la **misma tag** para *path operations* relacionadas.

En estos casos, podría tener sentido almacenar las tags en un `Enum`.

**FastAPI** soporta eso de la misma manera que con strings normales:

    /** Path prefix for API endpoints. */
    protected String pathPrefix;

    /**
     * Enumeration of supported API format types.
     */
    protected enum FormatType {
        /** Search API format. */
        SEARCH,
        /** Label API format. */
        LABEL,
        /** Popular word API format. */
        POPULARWORD,
        /** Favorite API format. */

              + " but returned result: "
              + result);
    } else {
      throw new AssertionError("expected to throw " + expectedThrowable.getSimpleName());
    }
  }

  private enum PlatformSpecificExceptionBatch {
    PLATFORM {
      @GwtIncompatible
      @J2ktIncompatible
      @Override
      // returns the types available in "normal" environments

In diesem Fall gibt es drei Query-Parameter:

* `needy`, ein erforderlicher `str`.
* `skip`, ein `int` mit einem Defaultwert `0`.
* `limit`, ein optionales `int`.

/// tip | Tipp

Sie können auch `Enum`s verwenden, auf die gleiche Weise wie mit [Pfad-Parametern](path-params.md#vordefinierte-parameterwerte){.internal-link target=_blank}.

  }

  private static void assertFailsToDecode(
      BaseEncoding encoding, String cannotDecode, @Nullable String expectedMessage) {
    // We use this somewhat weird pattern with an enum for each assertion we want to make as a way
    // of dealing with the fact that one of the assertions is @GwtIncompatible but we don't want to
    // have to have duplicate @GwtIncompatible test methods just to make that assertion.

    private final ConcurrentHashMap<String, ChangeNotificationHandle> activeWatchers;
    private final ConcurrentHashMap<String, Integer> failureCounts;

    /**
     * Directory change types
     */
    public enum DirectoryChangeType {
        /**
         * File was added to the directory
         */
        FILE_ADDED,
        /**
         * File was removed from the directory
         */
        FILE_REMOVED,

public interface ModelBuilderRequest extends Request<Session> {

         */
        BUILD_PROJECT,
