NAME

       Class::MakeMethods::Template::PackageVar - Static methods with global variables

SYNOPSIS

         package MyObject;
         use Class::MakeMethods::Template::PackageVar (
           scalar          => [ 'foo' ]
         );

         package main;

         MyObject->foo('bar')
         print MyObject->foo();

         $MyObject::foo = 'bazillion';
         print MyObject->foo();

DESCRIPTION

       These meta-methods provide access to package (class global) variables.  These are
       essentially the same as the Static meta-methods, except that they use a global variable in
       the declaring package to store their values.

       Common Parameters: The following parameters are defined for PackageVar meta-methods.

       variable
           The name of the variable to store the value in. Defaults to the same name as the
           method.

   Standard Methods
       The following methods from Generic should all be supported:

         scalar
         string
         string_index (?)
         number
         boolean
         bits (?)
         array (*)
         hash (*)
         tiedhash (?)
         hash_of_arrays (?)
         object (?)
         instance (?)
         array_of_objects (?)
         code (?)
         code_or_scalar (?)

       See Class::MakeMethods::Template::Generic for the interfaces and behaviors of these method
       types.

       The items marked with a * above are specifically defined in this package, whereas the
       others are formed automatically by the interaction of this package's generic settings with
       the code templates provided by the Generic superclass.

       The items marked with a ? above have not been tested sufficiently; please inform the
       author if they do not function as you would expect.

   PackageVar:vars
       This rewrite rule converts package variable names into PackageVar methods of the
       equivalent data type.

       Here's an example declaration:

         package MyClass;

         use Class::MakeMethods::Template::PackageVar (
           vars => '$DEBUG %Index'
         );

       MyClass now has methods that get and set the contents of its $MyClass::DEBUG and
       %MyClass::Index package variables:

         MyClass->DEBUG( 1 );
         MyClass->Index( 'foo' => 'bar' );
