# ABSTRACT: Make your object constructors blow up on unknown attributes

=head1 NAME
MooseX::StrictConstructor - Make your object constructors blow up on unknown attributes
=head1 VERSION
version 0.21
=head1 SYNOPSIS
package My::Class;
use Moose;
use MooseX::StrictConstructor;
has 'size' => ( is => 'ro' );
# then later ...
# this blows up because color is not a known attribute
My::Class->new( size => 5, color => 'blue' );
=head1 DESCRIPTION
Simply loading this module makes your constructors "strict". If your
constructor is called with an attribute init argument that your class does not
declare, then it calls C<< Moose->throw_error() >>. This is a great way to
catch small typos.
=head2 Subverting Strictness
You may find yourself wanting to have your constructor accept a
parameter which does not correspond to an attribute.
In that case, you'll probably also be writing a C<BUILD()> or
C<BUILDARGS()> method to deal with that parameter. In a C<BUILDARGS()>
method, you can simply make sure that this parameter is not included
in the hash reference you return. Otherwise, in a C<BUILD()> method,
you can delete it from the hash reference of parameters.
sub BUILD {
my $self = shift;
my $params = shift;
if ( delete $params->{do_something} ) {
...
}
}
=head1 BUGS
Please report any bugs or feature requests to
C<bug-moosex-strictconstructor@rt.cpan.org>, or through the web
interface at L<http://rt.cpan.org>. I will be notified, and then
you'll automatically be notified of progress on your bug as I make
changes.
Bugs may be submitted at L<https://github.com/moose/MooseX-StrictConstructor/issues>.
I am also usually active on IRC as 'autarch' on C<irc://irc.perl.org>.

=head1 DONATIONS
If you'd like to thank me for the work I've done on this module, please
consider making a "donation" to me via PayPal. I spend a lot of free time
creating free software, and would appreciate any support you'd care to offer.
Please note that B<I am not suggesting that you must do this> in order for me
to continue working on this particular software. I will continue to do so,
inasmuch as I have in the past, for as long as it interests me.
Similarly, a donation made in this way will probably not make me work on this
software much more, unless I get so many donations that I can consider working
on free software full time (let's all have a chuckle at that together).
To donate, log into PayPal and send money to autarch@urth.org, or use the
button at L<http://www.urth.org/~autarch/fs-donation.html>.
