NAME

       Moose::Meta::Attribute::Native::Trait::Counter - Helper trait for Int attributes which represent counters

VERSION

       version 2.0604

SYNOPSIS

	 package MyHomePage;
	 use Moose;

	 has 'counter' => (
	     traits  => ['Counter'],
	     is      => 'ro',
	     isa     => 'Num',
	     default => 0,
	     handles => {
		 inc_counter   => 'inc',
		 dec_counter   => 'dec',
		 reset_counter => 'reset',
	     },
	 );

	 my $page = MyHomePage->new();
	 $page->inc_counter;	# same as $page->counter( $page->counter + 1 );
	 $page->dec_counter;	# same as $page->counter( $page->counter - 1 );

	 my $count_by_twos = 2;
	 $page->inc_counter($count_by_twos);

DESCRIPTION

       This trait provides native delegation methods for counters. A counter can be any sort of number (integer or not). The delegation methods
       allow you to increment, decrement, or reset the value.

DEFAULT TYPE

       If you don't provide an "isa" value for your attribute, it will default to "Num".

PROVIDED METHODS

       o   set($value)

	   Sets the counter to the specified value and returns the new value.

	   This method requires a single argument.

       o   inc

       o   inc($arg)

	   Increases the attribute value by the amount of the argument, or by 1 if no argument is given. This method returns the new value.

	   This method accepts a single argument.

       o   dec

       o   dec($arg)

	   Decreases the attribute value by the amount of the argument, or by 1 if no argument is given. This method returns the new value.

	   This method accepts a single argument.

       o   reset

	   Resets the value stored in this slot to its default value, and returns the new value.

NAME

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

VERSION

       version 2.0604

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'.
