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

version 0.21

    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' );

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.

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} ) {
          ...
      }
  }

Please report any bugs or feature requests to "bug-moosex-strictconstructor@rt.cpan.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".

The source code repository for MooseX-StrictConstructor can be found at <https://github.com/moose/MooseX-StrictConstructor>.

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@urth.org, or use the button at <http://www.urth.org/~autarch/fs-donation.html>.
