For example, the access to
wheel:*:0:root,rudo,kenkenin /etc/group is "unixgroup:wheel" map in IO::Adapter.
$obj = new IO::Adapter "unixgroup:wheel";If you call get_next_key() method for this object, you will get the member of wheel group sequentially. In other words the wheel group is regarded as the following file by IO::Adapter.
