Subject: Re: Pretty printing IP addresses From: Erik Naggum <firstname.lastname@example.org> Date: 23 Sep 2002 20:22:06 +0000 Newsgroups: comp.lang.lisp Message-ID: <email@example.com> * Matthew X. Economou | I'm writing some code that manipulates IP addresses. A class wrapper around a one-element vector specialized to contain 32-bit integers seems like a good choice. Provide readers and setters that return and accept (respectively) a string, an integer, and four bytes. | I would like to give the IP address object a pretty-printable and readable | representation. Simple and easy with a class wrapper. | Currently, I'm using a DEFTYPE declaration of (SIMPLE-BIT-VECTOR 32) Why on earth? The overhead of constructing and deconstructing it bit by bit must be enormous. | Is there a better way? See `print-object´. Specialize methods on it for your wrapper class. -- Erik Naggum, Oslo, Norway Act from reason, and failure makes you rethink and study harder.
