MooseX::StrictConstructor(3pm) User Contributed Perl Documentation MooseX::StrictConstructor(3pm)
NAME
MooseX::StrictConstructor - Make your object constructors blow up on unknown attributes
VERSION
version 0.21
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' );
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
"Moose->throw_error()". This is a great way to catch small typos.
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 "BUILD()" or "BUILDARGS()" method to deal
with that parameter. In a "BUILDARGS()" method, you can simply make sure that this
parameter is not included in the hash reference you return. Otherwise, in a "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} ) {
...
}
}
BUGS
Please report any bugs or feature requests to "bug-moosex-strictconstructor AT rt.org",
or through the web interface at <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 <https://github.com/moose/MooseX-StrictConstructor/issues>.
I am also usually active on IRC as 'autarch' on "irc://irc.perl.org".

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 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 AT urth.org, or use the button at
