34 The MakeMethods subclass provides accessor methods that search an
35 inheritance tree to find a value. This allows you to set a shared or
36 default value for a given class, and optionally override it in a
37 subclass.

39 Standard Methods
40 The following methods from Generic should be supported:

45 number
46 boolean (?)
47 bits (?)
48 array (?)
49 hash (?)

57
58 See Class::MakeMethods::Template::Generic for the interfaces and
59 behaviors of these method types.
60
61 The items marked with a * above are specifically defined in this
62 package, whereas the others are formed automatically by the interaction
63 of this package's generic settings with the code templates provided by
64 the Generic superclass.
65
66 The items marked with a ? above have not been tested sufficiently;
67 please inform the author if they do not function as you would expect.
68
70 See Class::MakeMethods for general information about this distribution.
71
72 See Class::MakeMethods::Template for more about this family of
73 subclasses.
74
75 See Class::MakeMethods::Template::Generic for information about the
76 various accessor interfaces subclassed herein.
77
78 If you just need scalar accessors, see Class::Data::Inheritable for a
79 very elegant and efficient implementation.
