6 Class::MakeMethods::Template::PackageVar - Static methods with global
7 variables
8
10 package MyObject;
11 use Class::MakeMethods::Template::PackageVar (
12 scalar => [ 'foo' ]
13 );
14
15 package main;
16
17 MyObject->foo('bar')
18 print MyObject->foo();
19
20 $MyObject::foo = 'bazillion';
21 print MyObject->foo();
22
24 These meta-methods provide access to package (class global) variables.
25 These are essentially the same as the Static meta-methods, except that
26 they use a global variable in the declaring package to store their val‐
27 ues.
28
29 Common Parameters: The following parameters are defined for PackageVar
30 meta-methods.
31
32 variable
33 The name of the variable to store the value in. Defaults to the
34 same name as the method.
35
36 Standard Methods
37
38 The following methods from Generic should all be supported:
39
40 scalar
41 string
42 string_index (?)
43 number
44 boolean
45 bits (?)
46 array (*)
47 hash (*)
48 tiedhash (?)
49 hash_of_arrays (?)
50 object (?)
51 instance (?)
52 array_of_objects (?)
53 code (?)
54 code_or_scalar (?)
55
56 See Class::MakeMethods::Template::Generic for the interfaces and behav‐
57 iors of these method types.
58
59 The items marked with a * above are specifically defined in this pack‐
60 age, whereas the others are formed automatically by the interaction of
61 this package's generic settings with the code templates provided by the
62 Generic superclass.
63
64 The items marked with a ? above have not been tested sufficiently;
65 please inform the author if they do not function as you would expect.
66
67 PackageVar:vars
68
69 This rewrite rule converts package variable names into PackageVar meth‐
70 ods of the equivalent data type.
71
72 Here's an example declaration:
73
74 package MyClass;
75
76 use Class::MakeMethods::Template::PackageVar (
77 vars => '$DEBUG %Index'
78 );
79
80 MyClass now has methods that get and set the contents of its
81 $MyClass::DEBUG and %MyClass::Index package variables:
82
83 MyClass->DEBUG( 1 );
84 MyClass->Index( 'foo' => 'bar' );
