## Interface DynUnion

- All Superinterfaces:
    DynAny, Object

  Deprecated.
  Use the new DynUnion instead

      @Deprecated
      public interface DynUnion
      extends Object, DynAny

  The `DynUnion` interface represents a `DynAny` object that is associated with an IDL union. Union values can be traversed using the operations defined in `DynAny`. The first component in the union corresponds to the discriminator; the second corresponds to the actual value of the union. Calling the method `next()` twice allows you to access both components.

    All Methods Instance Methods Abstract Methods Deprecated Methods
    Modifier and Type | Method and Description
    --- | ---
    `TCKind` | `discriminator_kind()` Deprecated. Returns the TCKind object associated with the discriminator of this union.
    `DynAny` | `discriminator()` Deprecated. Returns a DynAny object reference that must be narrowed to the type of the discriminator in order to insert/get the discriminator value.
    `TCKind` | `member_kind()` Deprecated. Returns the TCKind associated with the member of this union.
    `String` | `member_name()` Deprecated. Allows for the inspection of the name of this union member without checking the value of the discriminator.
    `void` | `member_name(String arg)` Deprecated. Allows for the assignment of the name of this union member.
    `DynAny` | `member()` Deprecated. Returns a DynAny object reference that is used in order to insert/get a member of this union.
    `boolean` | `set_as_default()` Deprecated. Determines whether the discriminator associated with this union has been assigned a valid default value.
    `void` | `set_as_default(boolean arg)` Deprecated. Determines whether the discriminator associated with this union gets assigned a valid default value.

    - #### discriminator

          DynAny discriminator()

      Deprecated.
      Returns a DynAny object reference that must be narrowed to the type of the discriminator in order to insert/get the discriminator value.

        a `DynAny` object reference representing the discriminator value

    - #### discriminator_kind

          TCKind discriminator_kind()

      Deprecated.
      Returns the TCKind object associated with the discriminator of this union.
      Returns:
        the `TCKind` object associated with the discriminator of this union

    - #### member

          DynAny member()

      Deprecated.

        the `DynAny` object representing a member of this union

    - #### member_name

          String member_name()

      Deprecated.
      Allows for the inspection of the name of this union member without checking the value of the discriminator.
