NAME
       MouseX::AttributeHelpers	- Extend your attribute	interfaces

SYNOPSIS
	   package MyClass;

	   use Mouse;
	   use MouseX::AttributeHelpers;

	   has 'mapping' => (
	       metaclass => 'Collection::Hash',
	       is	 => 'rw',
	       isa	 => 'HashRef',
	       default	 => sub	{ +{} },
	       provides	 => {
		   exists => 'exists_in_mapping',
		   keys	  => 'ids_in_mapping',
		   get	  => 'get_mapping',
		   set	  => 'set_mapping',
	       },
	   );

	   package main;

	   my $obj = MyClass->new;
	   $obj->set_quantity(10);	# quantity => 10
	   $obj->set_mapping(4,	'foo');	# 4 => 'foo'
	   $obj->set_mapping(5,	'bar');	# 5 => 'bar'
	   $obj->set_mapping(6,	'baz');	# 6 => 'baz'

	   # prints 'bar'
	   print $obj->get_mapping(5) if $obj->exists_in_mapping(5);

	   # prints '4,	5, 6'
	   print join ', ', $obj->ids_in_mapping;

DESCRIPTION
       MouseX::AttributeHelpers	provides commonly used attribute helper
       methods for more	specific types of data.

       As seen in the "SYNOPSIS", you specify the extension via	the
       "metaclass" parameter.

PARAMETERS
   provides
       This points to a	hashref	that uses "provider" for the keys and "method"
       for the values. The method will be added	to the object itself and do
       what you	want.

   curries
       This points to a	hashref	that uses "provider" for the keys and has two
       choices for the value:

       You can supply "{ method	=> \@args }" for the values.  The method will
       be added	to the object itself (always using @args as the	beginning
       arguments).

       Another approach	to curry a method provider is to supply	a coderef
       instead of an arrayref. The code	ref takes $self, $body,	and any
       additional arguments passed to the final	method.

METHOD PROVIDERS
   Counter
       Methods for incrementing	and decrementing a counter attribute.

   Number
       Common numerical	operations.

   String
       Common methods for string values.

   Bool
       Common methods for boolean values.

   Collection::List
       Common list methods for array references.

   Collection::Array
       Common methods for array	references.

   Collection::ImmutableHash
       Common methods for hash references.

   Collection::Hash
       Common additional methods for hash references.

   Collection::Bag
       Methods for incrementing	and decrementing a value of collection.
