Call a protected method (constructor) via RTTI

Question

am using XE-2.

Is it possible to invoke a protected method (constructor) using RTTI?

I searched the web but did not find any conclusive answer. I understand that prior to XE only published methods/properties were available. I do have write access to private fields, so I was expecting to be able to invoke protected methods.

The following code works as long as the constructor is public.

function GetDefaultConstructor(aRttiType: TRttiType): TRttiMethod;
var
   Method: TRttiMethod;
begin
   for Method in aRttiType.GetMethods('Create') do
   begin
      if (Method.IsConstructor) and (length(Method.GetParameters) = 0) and (Method.Parent = aRttiType) then
         Exit(Method);
   end;
   Result := nil;
end;

By the default the RTTI doesn't include info about the protected methods or constructors, However you can use RTTI EXPLICIT Directive to include RTTI info of protected methods like so.

  {$RTTI EXPLICIT METHODS([vcPrivate, vcProtected, vcPublic, vcPublished])}
  TFoo= class
  protected
    constructor Create;
  end;
