=head1 NAME
Moose::Meta::Attribute::Native::Trait::Bool - Helper trait for Bool attributes
=head1 VERSION
version 2.1405
=head1 SYNOPSIS
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->new();
$room->illuminate; # same as $room->is_lit(1);
$room->darken; # same as $room->is_lit(0);
$room->flip_switch; # same as $room->is_lit(not $room->is_lit);
return $room->is_dark; # same as !$room->is_lit
=head1 DESCRIPTION
This trait provides native delegation methods for boolean values. A boolean is
a scalar which can be C<1>, C<0>, C<"">, or C<undef>.
=head1 DEFAULT TYPE
If you don't provide an C<isa> value for your attribute, it will default to
C<Bool>.
=head1 PROVIDED METHODS
None of these methods accept arguments.
=over 4
=item * B<set>
Sets the value to C<1> and returns C<1>.
=item * B<unset>
Set the value to C<0> and returns C<0>.
=item * B<toggle>
Toggles the value. If it's true, set to false, and vice versa.
Returns the new value.
=item * B<not>
Equivalent of 'not C<$value>'.
