Can someone tell me how to do this?
Just a thought that entered my mind when learning about structs.
First thought was:
struct one
{
struct two;
}
struct two
{
three;
}
one->two->three
would this be how you would access "three"? (1 Reply)

Hi,
I believe the next code is wrong:
class Egg {
Egg e;
int i;
Egg(int ii=0) : i(ii) {}
};
because you would end up with an endless definition (memory allocation) of Egg objects, thus int i.
Ok, so God Eckel proposes for a singleton:
class Egg {
static Egg e;

package::new
Package::New(3pm) User Contributed Perl Documentation Package::New(3pm)
NAME
Package::New - Simple base package from which to inherit
SYNOPSIS
package My::Package;
use base qw{Package::New}; #provides new and initialize
DESCRIPTION
The Package::New object provides a consistent constructor for objects.
I find that I always need these two methods in every package that I build. I plan to use this package as the base for all of my CPAN
packages.
RECOMMENDATIONS
Sane defaults
I recommend that you have sane default for all of your object properties. I recommend using code like this.
sub myproperty {
my $self=shift;
$self->{"myproperty"}=shift if @_;
$self->{"myproperty"}="Default Value" unless defined $self->{"myproperty"};
return $self->{"myproperty"};
}
use strict and warnings
I recommend to always use strict, warnings and our version.
package My::Package;
use base qw{Package::New};
use strict;
use warnings;
our $VERSION='0.01';
Lazy Load where you can
I recommend Lazy Loading where you can.
sub mymethod {
my $self=shift;
$self->load unless $self->loaded;
return $self->{"mymethod"};
}
USAGE
CONSTRUCTOR
new
my $obj = Package::New->new(key=>$value, ...);
initialize
You can override this method in your package if you need to do something after construction. But, lazy loading may be a better option.
