NAME

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

VERSION

       version 2.0603

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.

       o   set

	   Sets the value to 1 and returns 1.

       o   unset

	   Set the value to 0 and returns 0.

       o   toggle

	   Toggles the value. If it's true, set to false, and vice versa.

	   Returns the new value.

       o   not

	   Equivalent of 'not $value'.
