NAME ^

Moose::Meta::Attribute::Native::Trait::Bool - Helper trait for Bool attributes

VERSION ^

version 2.1004

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.
