- - ### Field Detail

    - #### field1

          public Winevt.EVT_VARIANT.field1_union field1

      Exposed to follow JNA rules, use the `getValue()` method to manipulate values!

    - #### Count

          public int Count

      The number of elements in the array of values. Use Count if the Type member has the EVT_VARIANT_TYPE_ARRAY flag set.

      Exposed to follow JNA rules, use `getValue()` and `setValue(com.sun.jna.platform.win32.Winevt.EVT_VARIANT_TYPE, java.lang.Object)` methods to manipulate values!

    - #### Type

          public int Type

      A flag that specifies the data type of the variant. For possible values, see the `Winevt.EVT_VARIANT_TYPE` enumeration. The variant contains an array of values, if the EVT_VARIANT_TYPE_ARRAY flag is set. The members that end in "Arr" contain arrays of values. For example, you would use the StringArr member to access the variant data if the type is EvtVarTypeString and the EVT_VARIANT_TYPE_ARRAY flag is set. You can use the `Winevt.EVT_VARIANT_TYPE_MASK` constant to mask out the array bit to determine the variant's type.

      Exposed to follow JNA rules, use `getValue()` and `setValue(com.sun.jna.platform.win32.Winevt.EVT_VARIANT_TYPE, java.lang.Object)` methods to manipulate values!

  - ### Constructor Detail

    - #### Winevt.EVT_VARIANT

          public Winevt.EVT_VARIANT()

    - #### Winevt.EVT_VARIANT

          public Winevt.EVT_VARIANT(Pointer peer)

  - ### Method Detail

    - #### getFieldOrder

          protected java.util.List<java.lang.String> getFieldOrder()

      Description copied from class: `Structure`
      Return this Structure's field names in their proper order. For example,

           protected List getFieldOrder() {
               return Arrays.asList(new String[] { ... });
           }

      IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.

           protected List getFieldOrder() {
               List fields = new ArrayList(super.getFieldOrder());
               fields.addAll(Arrays.asList(new String[] { ... }));
               return fields;
           }

      Field order must be explicitly indicated, since the field order as returned by `Class.getFields()` is not guaranteed to be predictable.
      Specified by:
        `getFieldOrder` in class `Structure`
      Returns:
        ordered list of field names

    - #### use

    - #### isArray

          public boolean isArray()

    - #### getVariantType

          public Winevt.EVT_VARIANT_TYPE getVariantType()

    - #### setValue

          public void setValue(Winevt.EVT_VARIANT_TYPE type,
                      java.lang.Object value)

      Parameters:
        `type` -
        `value` -

    - #### getValue

          public java.lang.Object getValue()

      Returns:
        value contained in the EVT_VARIANT
