NAME¶
MooseX::UndefTolerant::Attribute - Make your attribute(s) tolerant to undef
intitialization
VERSION¶
version 0.19
SYNOPSIS¶
package 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!
DESCRIPTION¶
Applying 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.
