SYNOPSIS

  package Room;
  use Moose;
  has 'is_lit' => (
      traits  => ['Bool'],
      is      => 'rw',
      isa     => 'Bool',

      handles => {
          illuminate  => 'set',

          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);

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'.
