Base class for all Java mappings of interface definition language enumerated types.

The interface language definition type system includes enumerated types. For every such enumerated type a class which extends this class is generated (referred to as enumeration class). The generated class contains public static member fields initialized with instances of the class for each enumeration constant.

In addition, the generated enumeration class contains inner native Java enum declaraing the same constants. This native enum can be used for more convenient handling of enumerations, e.g. in usage in switch statements. The simple name of the inner native enum is always Values.

Example of generated "enumeration class" and its inner native enum:

  public final class SourceType extends com.vmware.vapi.bindings.ApiEnumeration {

      public static final SourceType FILE = new SourceType("FILE");

      public static final SourceType REMOTE = new SourceType("REMOTE");

      public enum Values {
          FILE,
          REMOTE,
          _UNKNOWN,
      }
      ...
  }
 

Example of obtaining native enum constant corresponding to given enumeration class constant

   SourceType sourceType = SourceType.FILE;
   SourceType.Values nativeEnumValue = sourceType.getEnumValue();

   // can use it in switch statement
   switch (nativeEnumValue) {
      case: ...
   }
 

Note:The generated enumeration class defines constants representing the values in the current version of the enumerated type. Newer versions of the enumerated type may contain additional values. Such newer values are not known at generation and compile time. They are represented by the _UNKNOWN constant of the native enum and by an instance of the enumeration class which is not referred by any of the static member fields of the class. For the enumeration class instances conversion to and from String is supported, which allows usage of such newer constants.

  // create enumeration class instance for the newer value FOLDER
  SourceType sourceType = SourceType.valueOf("FOLDER");

  // obtain String representation of the newer value (e.g. received from a
  // server which supports newer version of the API
  SourceType sourceType = ...
  String strValue = sourceType.name();
