Re: Re: Re: Re: Overloading inherited class methods

It was a problem here, but it may not have been completely obvious because I decided not to post the entire code of the superclass. However, the problem lies in issues like this:

  my ($class, %args) = @_;

If that occurs, I might append extra data to %args that does not logically belong there in all cases. However, if I convert %args to a reference, I can keep my "extra" info seperate and I don't have to build as many special cases in my code to account for the extra hash keys:

  my ($class, $args, $id) = @_;

(That's just an example, but you get the idea.) My problem lay in the fact that the subclassed constructor was expecting a single scalar id, which, if I passed the %args has from the get_list method, then the first element gets assigned to $id. Now, on second thought, I can see an error I made. I don't need to pass %args because the constructor already knows about it. Hmm... more work to do. Should take another two minutes :)

Update: Took me less than two minutes, actually. Now my methods in the subclass look like this:

sub new {
    my ($class,$id) = @_;
    $class->SUPER::new( %ARGS, open_id => $id );    
}

sub get_list {
    my $class = shift;
    $class->SUPER::get_list( %ARGS );
}

I am wondering now what would happen if I moved those into the superclass and exported them into subclasses (would that work? Then I wouldn't need to keep rewriting those methods for every class. I would just need to provide the %ARGS hash for configuration information and most objects would then simply use the superclass and have most of their methods just work. Interesting thought.
