Moose::Meta::Attribute::Native::Trait::Bool \u2212 Helper trait for Bool attributes<\/p>\n

VERSION <\/a> <\/h2>\n

version 2.2014<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

package Room;
use Moose;
has ‘is_lit’ => (
traits => [‘Bool’],
is => ‘rw’,
isa => ‘Bool’,
default => 0,
handles => {
illuminate => ‘set’,
darken => ‘unset’,
flip_switch => ‘toggle’,
is_dark => ‘not’,
},
);
my $room = Room\u2212>new();
$room\u2212>illuminate; # same as $room\u2212>is_lit(1);
$room\u2212>darken; # same as $room\u2212>is_lit(0);
$room\u2212>flip_switch; # same as $room\u2212>is_lit(not $room\u2212>is_lit);
return $room\u2212>is_dark; # same as !$room\u2212>is_lit<\/p>\n

DESCRIPTION <\/a> <\/h2>\n

This trait provides native delegation methods for boolean values. A boolean is a scalar which can be 1, 0, “”, or “undef”.<\/p>\n

DEFAULT TYPE <\/a> <\/h2>\n

If you don\u2019t provide an “isa” value for your attribute, it will default to “Bool”.<\/p>\n

PROVIDED METHODS <\/a> <\/h2>\n

None of these methods accept arguments.<\/p>\n\n\n
