I have two classes, each has a constructor named new. I want to subclass the classes to make a new class. I need to call both parent constructors. However, how do I call the second constructor without clobbering by the data instance variables from first one? I can't seem to find this anywhere in the perldocs or in the Manning book.
Thanks,
Bizzach
package PClass1;
use strict;
use Carp;
sub new {
my $proto = shift;
my $class = ref($proto) || $proto;
my (%args) = @_;
my $this = {
_fs => $args{fs} || croak("You must supply a filesystem"),
};
bless $this, $class;
return $this;
}
...
package PClass2;
use strict;
sub new {
my $proto = shift;
my $class = ref($proto) || $proto;
my (%args) = @_;
my $this = {
_hosts => $args{hosts},
};
bless $this, $class;
return $this;
}
......
package Subclass;
use strict;
use PClass1;
use PClass2;
our @ISA=qw(PClass1 PClass2);
sub new {
my ($class, %args) = @_;
my $this = {};
bless $this, $class;
$this = $class->PClass1::new(%args);
#HOW DO I CALL THE SECOND CONSTRUCTOR HERE?????
$this->init($this);
return $this;
}
