attributes
VERSION
version 2.0402
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
DESCRIPTION
This trait provides native delegation methods for boolean values. A
boolean is a scalar which can be 1, 0, "", or "undef".
DEFAULT TYPE
If you don't provide an "isa" value for your attribute, it will default
to "Bool".
PROVIDED METHODS
None of these methods accept arguments.
· set
Sets the value to 1 and returns 1.
· unset
Set the value to 0 and returns 0.
· toggle
Toggles the value. If it's true, set to false, and vice versa.
Returns the new value.
· not
Equivalent of 'not $value'.
