NAME

7

SYNOPSIS

9         package MyObject;
10         use Class::MakeMethods::Template::InsideOut (
11           scalar          => [ 'foo', 'bar' ]
12         );
13         sub new { ... }
14
15         package main;
16
17         my $obj = MyObject->new( foo => "Foozle", bar => "Bozzle" );
18         print $obj->foo();            # Prints Foozle
19         $obj->bar("Bamboozle");       # Sets $obj's bar value

DESCRIPTION

22       Supports the Generic object constructor and accessors meta-method
23       types, but accepts any object as the underlying implementation type,
24       with member data stored in external indices.
25
26       Each method stores the values associated with various objects in an
27       hash keyed by the object's stringified identity. Since that hash is
28       accessible only from the generated closures, it is impossible for
29       foreign code to manipulate those values except through the method
30       interface.
31
32       A DESTROY method is installed to remove data for expired objects from
33       the various hashes. (If the DESTROY method is not called, your program
34       will not release this data and memory will be wasted.)
35
36       Common Parameters: The following parameters are defined for InsideOut
37       meta-methods.
38
39       data
40           An auto-vivified reference to a hash to be used to store the values
41           for each object.
42
43       Note that using InsideOut meta-methods causes the installation of a
44       DESTROY method in the calling class, which deallocates data for each
45       instance when it is discarded.
46
47       NOTE: This needs some more work to properly handle inheritance.
48
49   Standard Methods
50       The following methods from Generic are all supported:
51
52         scalar
53         string
54         string_index *
55         number
56         boolean
57         bits
58         array
59         hash
60         tiedhash
61         hash_of_arrays
62         object
63         instance
64         array_of_objects
65         code
66         code_or_scalar
67
68       See Class::MakeMethods::Template::Generic for the interfaces and
69       behaviors of these method types.
70
71       The items marked with a * above are specifically defined in this
72       package, whereas the others are formed automatically by the interaction
73       of this package's generic settings with the code templates provided by
74       the Generic superclass.
75
76   boolean_index
77         boolean_index => [ qw / foo bar baz / ]
78
79       Like InsideOut:boolean, boolean_index creates x, set_x, and clear_x
80       methods. However, it also defines a class method find_x which returns a
81       list of the objects which presently have the x-flag set to true.
82
83       Note that to free items from memory, you must clear these bits!
