Hi Monks,

I've been trying to search for a solution to this for days; any help would be appreciated. Basically, I have a series of classes inheriting from each other, for example, class B is a subclass of class A, and class C is a subclass of class B.

There is an A->source() method defined, which may be overridden in class B. Now in a separate method defined in class A, say:

sub readsource {
  my $Class = shift;
  ...
  $Class->source();
}

[download]

So in this method I would like to know in which class the call to $Class->source() will find the source() method.

That is, if source() is not overridden in class B, then calling C->readsource() should know that it accesses A->source() when it calls C->source(). But if source() is overridden, then it should know that it uses B->source().

I would use this information in readsource() to create a new method in the class where I've found source(), a bit like what happens in Class::Data::Inheritable (which appears to use closures to remember where the accessor was defined).

Is there a way to do this without manually parsing the @ISA of all the classes involved?
