The Art of the Metaobject Protocol
Gregor KiczalesISBN: 0262610744; 9780262610742;
This book details the meta-object protocol, the framework on which the Common Lisp object system (CLOS) is based. The philosophy behind the meta-object protocol is that different applications may require different kinds of object models, and so the object model itself should be subject to program control. The Art of the Meta-Object Protocol provides a wonderful working example of how Lisp can be extended and how it can evolve to incorporate new language constructs. First, the book describes how CLOS is actually implemented by working through a subset. Then it goes on to develop the meta- object protocol in great detail. The Art of the Meta-Object Protocol is useful for the advanced CLOS user as well as for anyone interested in object-oriented programming and language design.
