Re^2: using passed parent object reference to get at attributes

I wondered about doing "use parent" instead of working with @ISA for the test case. I didn't know but it turns out you can if the Perl isn't really ancient (I think you need 5.10.1). Instead of:

push @cChild::ISA, 'cParent';
[download]

one could also:

use parent -norequire, 'cParent';
[download]

In the real application, as opposed to the test example, the classes are probably broken up into seperate files and you probably just remove the '-norequire, '.

@ISA is something I knew nothing about so thanks for raising it as a possibility...I see it's "Each package contains a special array called @ISA . The @ISA array contains a list of that class's parent classes, if any. This array is examined when Perl does method resolution, which we will cover later. " Thank you for the education!	[reply]
