NAMESort::Key::Register - tell Sort::Key how to sort new data types.SYNOPSISuse Sort::Key::Register Person => sub { $_->surname, $_->name }, qw(string string); use Sort::Key::Register 'Color::Component' => 'integer'; use Sort::Key::Register Color => sub { $_->R, $_->G, $_->B }, ('Color::Component') x 3; DESCRIPTIONSort::Key::Register allows one to register new data types with Sort::Key so that they can be sorted as natively supported ones.It works as a pragma module and doesn't export any function, all its functionality is provided via "use": use Sort::Key::Register ... To avoid collisions between modules registering types with the same name, you should qualify them with the package name. use Sort::Key::Register 'MyPkg::foo' => sub { $_ }, '-int'; # or using __PACKAGE__: use Sort::Key::Register __PACKAGE__, sub { $_ }, '-int'; USAGE
