18 This document describes the various subclasses of Class::MakeMethods
19 included under the Standard::* namespace, and the method types each one
20 provides.
21
22 The Standard subclasses provide a parameterized set of method-
23 generation implementations.
24
25 Subroutines are generated as closures bound to a hash containing the
26 method name and (optionally) additional parameters.
27
28 Calling Conventions
29 When you "use" a subclass of this package, the method declarations you
30 provide as arguments cause subroutines to be generated and installed in
31 your module. You can also omit the arguments to "use" and instead make
32 methods at runtime by passing the declarations to a subsequent call to
33 "make()".
34
35 You may include any number of declarations in each call to "use" or
36 "make()". If methods with the same name already exist, earlier calls to
37 "use" or "make()" win over later ones, but within each call, later
38 declarations superceed earlier ones.
39
40 You can install methods in a different package by passing
41 "-target_class => package" as your first arguments to "use" or "make".
42
43 See "USAGE" in Class::MakeMethods for more details.
44
45 Declaration Syntax
46 The following types of Simple declarations are supported:
47
48 · generator_type => 'method_name'
49
50 · generator_type => 'name_1 name_2...'
51
52 · generator_type => [ 'name_1', 'name_2', ...]
53
54 For a list of the supported values of generator_type, see "STANDARD
55 CLASSES" in Class::MakeMethods::Docs::Catalog, or the documentation for
56 each subclass.
57
58 For each method name you provide, a subroutine of the indicated type
59 will be generated and installed under that name in your module.
60
61 Method names should start with a letter, followed by zero or more
62 letters, numbers, or underscores.
63
64 Parameter Syntax
65 The Standard syntax also provides several ways to optionally associate
66 a hash of additional parameters with a given method name.
67
68 · generator_type => [
69 'name_1' => { param=>value... }, ...
70 ]
71
72 A hash of parameters to use just for this method name.
73
74 (Note: to prevent confusion with self-contained definition hashes,
75 described below, parameter hashes following a method name must not
76 contain the key 'name'.)
77
78 · generator_type => [
79 [ 'name_1', 'name_2', ... ] => { param=>value... }
80 ]
81
82 Each of these method names gets a copy of the same set of
83 parameters.
84
85 · generator_type => [
86 { 'name'=>'name_1', param=>value... }, ...
87 ]
88
89 By including the reserved parameter 'name', you create a self-
90 contained declaration with that name and any associated hash
91 values.
92
93 Simple declarations, as shown in the prior section, are treated as if
94 they had an empty parameter hash.
95
97 See Class::MakeMethods for general information about this distribution.
