Hi,

if I have an object of class Foo, or a subclass of Foo, like:

  Foo foo=someInstanceOfFooOrItsSubclasses();

Is there a more elegant method to get the type of the object
than adding a member function to Foo and all its subclasses
that does something like:

  TypeInfo getType()
  {
    return typeid(typeof(this));
  }

?

Regards, Frank

May I "if (theInstance.classinfo==TheClass.classinfo)"?

Seems to work...

Does the comment about Typeinfo and Polymorphism help you at all?

I'll take that as a "yes"... =)
I was mainly concerned here if using the classinfo member counts
as a hackish OMGWhatHaveYouGoneAndDoneNow??? or if it's okay to.

Thanks, Frank

That sounds ok.  If you want to see hackish uses of classinfo go visit the source code for std.boxer.
