Moose::Meta::Attribute::Native::Trait::Bool - Helper trait for Bool attributes
version 2.1201
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
This trait provides native delegation methods for boolean values. A boolean is a scalar which can be 1, 0, "", or undef.
1
0
""
undef
If you don't provide an isa value for your attribute, it will default to Bool.
isa
Bool
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'.
$value
