public class Variant
extends java.lang.Object
The Variant types as defined by Microsoft's COM. I found this information in http://www.marin.clara.net/COM/variant_type_definitions.htm.
In the variant types descriptions the following shortcuts are used: [V] - may appear in a VARIANT, [T] - may appear in a TYPEDESC, [P] - may appear in an OLE property set, [S] - may appear in a Safe Array.
