Should you call a parent constructor explicitly like below - or does the
use base take care of this?
package Parent;
sub new {
my ($class, $arg1, $arg2) = @_;
my $self = {
arg1 => $arg1,
arg2 => $arg2
};
bless $self, $class;
return $self;
}
return 1;
package Child;
use base qw(Parent);
sub new {
my ($class, $arg1, $arg2, $arg3) = @_;
my $self = Parent->new($arg1, $arg2);
$self->{arg3} => $arg3;
bless $self, $class;
return $self;
}
return 1;
Also - is there a difference between
use base('Parent');
and
use Exporter;
use vars qw(@ISA);
@ISA = qw(Parent);
