NAME
MooseX::StrictConstructor - Make your object constructors blow up on unknown attributesVERSION
version 0.11SYNOPSIS
package My::Class; use Moose; use MooseX::StrictConstructor; has 'size' => ...; # 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 ``Carp::confess()''. 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} ) { ... } }
