Is it possible to get the value of a GUID on an interface using RTTI?

Question

If I have an interface such as:

IPluginAPI = interface
['{590DFF0B-CA00-46CC-84B0-3848103D4C5A}']
   function add (a : double; b : double) : double;
   function sub (a : double; b : double) : double;
   function mult (a : double; b : double) : double;
   function divide (a : double; b : double) : double;
end;

Is there anyway to get the value of the GUID using RTTI? I am using Delphi XE.

+1 Too bad the documentation is so far out of date....... – Ogata

Wow, that page is outright misleading. Note to self: Always see the source. – Amelita

+1, another option using the new Rtti TRttiInterfaceType(TRttiContext.Create.GetType(TypeInfo(IPluginAPI))).GUID – Gershwin

Answer 2

As mentioned by RRUZ in comment to older reply:

uses
  System.Rtti;

//...
var Guid := TRttiInterfaceType(TRttiContext.Create.GetType(TypeInfo(IPluginAPI))).GUID;
