NAME

6       MooseX::StrictConstructor - Make your object constructors blow up on
7       unknown attributes
8

VERSION

10       version 0.21
11

SYNOPSIS

13           package My::Class;
14
15           use Moose;
16           use MooseX::StrictConstructor;
17
18           has 'size' => ( is => 'ro' );
19
20           # then later ...
21
22           # this blows up because color is not a known attribute
23           My::Class->new( size => 5, color => 'blue' );
24

DESCRIPTION

26       Simply loading this module makes your constructors "strict". If your
27       constructor is called with an attribute init argument that your class
28       does not declare, then it calls "Moose->throw_error()". This is a great
29       way to catch small typos.
30
31   Subverting Strictness
32       You may find yourself wanting to have your constructor accept a
33       parameter which does not correspond to an attribute.
34
35       In that case, you'll probably also be writing a "BUILD()" or
36       "BUILDARGS()" method to deal with that parameter. In a "BUILDARGS()"
37       method, you can simply make sure that this parameter is not included in
38       the hash reference you return. Otherwise, in a "BUILD()" method, you
39       can delete it from the hash reference of parameters.
40
41         sub BUILD {
42             my $self   = shift;
43             my $params = shift;
44
45             if ( delete $params->{do_something} ) {
46                 ...
47             }
48         }

DONATIONS

66       If you'd like to thank me for the work I've done on this module, please
67       consider making a "donation" to me via PayPal. I spend a lot of free
68       time creating free software, and would appreciate any support you'd
69       care to offer.
70
71       Please note that I am not suggesting that you must do this in order for
72       me to continue working on this particular software. I will continue to
73       do so, inasmuch as I have in the past, for as long as it interests me.
74
75       Similarly, a donation made in this way will probably not make me work
76       on this software much more, unless I get so many donations that I can
77       consider working on free software full time (let's all have a chuckle
78       at that together).
79
80       To donate, log into PayPal and send money to autarch@urth.org, or use
81       the button at <http://www.urth.org/~autarch/fs-donation.html>.
