Question: Is there a way to tell whether a method is overloaded using rtti?

[pyscripter 689]

As per title.

 

For instance:

 

A)  Second method hides the first

 

ClassA = class
  procedure Test(I: Integer);
end;

ClassB = class(classA)
  procedure Test(S: string);
end;

 

B)  Second method overloads the first
 

ClassA = class
  procedure Test(I: Integer); overload;
end;

ClassB = class(classA)
  procedure Test(S: string); overload;
end;

 

How can you tell the difference with Rtti.  GetMethods would show both methods in a similar way.

Yes and no.

The overloaded methods will be listed one by one with the same name in getmethods but only the public ones.

But so do overwritten methods, virtual methods etc.

[Attila Kovacs 629]

hm, right. I think virtual / overriden having a DispatchKind of dkVtable and overwitten different parent.

A bit of puzzle.

No, RTTI does not contain any flag for a method being overloaded which makes it impossible to do proper overload resolution using RTTI because you cannot determine if a method would be "visible" or not.
