MooseX::UndefTolerant::Attribute(3pm) User Contributed Perl Documentation MooseX::UndefTolerant::Attribute(3pm)NAMEMooseX::UndefTolerant::Attribute - Make your attribute(s) tolerant to undef intitializationVERSIONversion 0.17SYNOPSISpackage My:Class; use Moose; use MooseX::UndefTolerant::Attribute; has 'bar' => ( traits => [ qw(MooseX::UndefTolerant::Attribute)], is => 'ro', isa => 'Num', predicate => 'has_bar' ); # Meanwhile, under the city... # Doesn't explode my $class = My::Class->new(bar => undef); $class->has_bar # False!DESCRIPTIONApplying this trait to your attribute makes it's initialization tolerant of of undef. If you specify the value of undef to any of the attributes they will not be initialized (or will be set to the default, if applicable). Effectively behaving as if you had not provided a value at all.AUTHORCory G Watson <gphat at cpan.org>COPYRIGHT AND LICENSEThis software is copyright (c) 2011 by Cory G Watson.
