C++ Gems
Stanley B. Lippman (editor) (1996)

Book review by Ted Felix

A collection of the best articles up to 1996 from the now-defunct C++ Report magazine. Actually, C++ Report was absorbed by the C/C++ Users Journal. Lots of stimulating reading for C++ aficionados, but the most useful article is entitled, "Callbacks in C++ Using Template Functors" by Rich Hickey. This article presents a callback mechanism for C++ that works very well. Unfortunately, it is a bit complex to understand and use, but it can come in very handy. The article itself discusses the various approaches to callbacks. Since callbacks are fundamental to decoupling classes, this is an important article.

There is also a follow-up to this book from 2000: More C++ Gems (SIGS Reference Library) which I have not read.
