NAME

       Class::Accessor::Class - simple class variable accessors

VERSION

       version 0.503

SYNOPSIS

       Set up a module with class accessors:

        package Text::Fortune;

        use base qw(Class::Accessor::Class Exporter);
        Robot->mk_class_accessors(qw(language offensive collection));

        sub fortune {
          if (__PACKAGE__->offensive) {
                ..

       Then, when using the module:

        use Text::Fortune;

        Text::Fortune->offensive(1);

        print fortune; # prints an offensive fortune

        Text::Fortune->language('EO');

        print fortune; # prints an offensive fortune in Esperanto

DESCRIPTION

       Class::Accessor::Class provides a simple way to create accessor and mutator methods for
       class variables, just as Class::Accessor provides for objects.  It can use either an
       enclosed lexical variable, or a package variable.

       This module was once implemented in terms of Class::Accessor, but changes to that module
       broke this relationship.  Class::Accessor::Class is still a subclass of Class::Accessor,
       strictly for historical reasons.  As a side benefit, a class that isa
       Class::Accessor::Class is also a Class::Accessor and can use its methods.

METHODS

   mk_class_accessors
        package Foo;
        use base qw(Class::Accessor::Class);
        Foo->mk_class_accessors(qw(foo bar baz));

        Foo->foo(10);
        my $obj = new Foo;
        print $obj->foo;   # 10

       This method adds accessors for the named class variables.  The accessor will get or set a
       lexical variable to which the accessor is the only access.

   mk_package_accessors
        package Foo;
        use base qw(Class::Accessor::Class);
        Foo->mk_package_accessors(qw(foo bar baz));

        Foo->foo(10);
        my $obj = new Foo;
        print $obj->foo;   # 10
        print $Foo::foo;    # 10

       This method adds accessors for the named class variables.  The accessor will get or set
       the named variable in the package's symbol table.

DETAILS

   make_class_accessor
        $accessor = Class->make_class_accessor($field);

       This method generates a subroutine reference which acts as an accessor for the named
       field.

   make_package_accessor
        $accessor = Class->make_package_accessor($field);

       This method generates a subroutine reference which acts as an accessor for the named
       field, which is stored in the scalar named "field" in "Class"'s symbol table.

       This can be useful for dealing with legacy code, but using package variables is almost
       never a good idea for new code.  Use this with care.
