NAME

6       Package::New - Simple base package from which to inherit
7

SYNOPSIS

9         package My::Package;
10         use base qw{Package::New}; #provides new and initialize
11

DESCRIPTION

13       The Package::New object provides a consistent constructor for objects.
14
15       I find that I always need these two methods in every package that I
16       build.  I plan to use this package as the base for all of my CPAN
17       packages.
18

RECOMMENDATIONS

20   Sane defaults
21       I recommend that you have sane default for all of your object
22       properties.  I recommend using code like this.
23
24         sub myproperty {
25           my $self=shift;
26           $self->{"myproperty"}=shift if @_;
27           $self->{"myproperty"}="Default Value" unless defined $self->{"myproperty"};
28           return $self->{"myproperty"};
29         }
30
31   use strict and warnings
32       I recommend to always use strict, warnings and our version.
33
34         package My::Package;
35         use base qw{Package::New};
36         use strict;
37         use warnings;
38         our $VERSION='0.01';
39
40   Lazy Load where you can
41       I recommend Lazy Loading where you can.
42
43         sub mymethod {
44           my $self=shift;
45           $self->load unless $self->loaded;
46           return $self->{"mymethod"};
47         }
48

USAGE

CONSTRUCTOR
51   new
52         my $obj = Package::New->new(key=>$value, ...);
53
54   initialize
55       You can override this method in your package if you need to do
56       something after construction.  But, lazy loading may be a better
57       option.
