I'm still relatively new to perl, so forgive the 'bad design' that everyone is talking about... but...

I wrote an object that had a hash ref as part of the object properties (set via the $obj=new CLASS or $obj->Req_Trace(\%mytrace) method)
* In order to ensure that I really had a hash (and not something else, 'case user made a mistake), I used something similar to this...

    my $self = shift;
    my %req = ();
    if (ref($self->Req_Trace()) eq "HASH") {
      %req = %{$self->Req_Trace()};
    }

Is this a case where using ref within an 'if' statement makes it ok?

Is using @ISA supposed to be used here? If so, how?

What don't I understand?

Could someone explain it to me? (assume that I am not knowledgable about much).

Thanks.
