Summary: Trying to do three things at once
Comment: Description
"Discovering CFCs" is a slim book of some 160 pages. Curiously, the paragraphs are numbered. There are some 350 paragraphs in total, plus an appendix chapter. Quite a lot of space is given to diagrams, pictures, and code examples. There is an accompanying workbook in PDF that can be purchased from the publishers techspedition. The authors Hal Helms and Ben Edwards are known to the ColdFusion community as a writer in "ColdFusion Developer's Journal" and as one of the people behind Fusebox.
The book has ten chapters. The first is an introduction and the last a short story. The eight core chapters explain the object-oriented concepts, how to do object-oriented programming with CFCs, and the limitations of CFCs with some workarounds.
The code examples are often first in Java and then in CFC. In comparison to the Java code it becomes obvious how painful it is to program CFCs, because of the markup-language syntax and the limitations of the language. Helms and Edwards provide good discussion of some of those limitations, and provide workarounds for them. Among the limitations they work around are
no private properties,
no constructors,
no super.
They also show how to use custom attributes and the meta-data to make self-documenting code. The book uses basic UML without making a big deal of it.
The last chapter is a fictitious conversation between three programmers about the pros and cons of object-oriented programming. It has a slight entertainment value, but doesn't really add much.
The book is aimed at CF developers who want to use CFCs. That is, they want to learn object orientation and how to do it with ColdFusion Components.
Critique
The book is trying to do three things at once:
1.Teach object-oriented programming.
2.Teach how to program CFCs.
3.Discuss limitations of CFCs and provide workarounds for them.
It would be better to do each of those things separately. A reader new to OO is likely to be confused by being taught an OO concept like super-class, then being shown an example in Java (a language that is besides the point of the book), then being shown the CFC code that takes half a page to do what Java does in three lines, and then the poor reader has to digest the limitations of CFCs and the suggested workarounds.
What will you get out of the book?
Readers who don't know OO need better examples and less syntax problems of CFC. They should not read this book, but one of the good books about OO using Java as example language.
Readers who know OO from Java or C++ or Smalltalk will find how to write CFCs. For them the OO stuff is superfluous. The book gives an introduction on how to write CFCs, but it does not cover the whole CFC syntax, so they will need the MX manual anyway. The book shows how to overcome some CFC weaknesses and that is useful.
As concerns style, I personally don't like so many footnotes, especially if they explain important things like the definition of "method signature". Some examples are unrealistic: a cat that knows it can sleep, eat, and play, is a taken as an example of an object with methods.

Summary: Techspedition has done it again.
Comment: Techspedition has done it again. In a refreshing and clear style, co-authors Hal Helms and Ben Edwards welcome readers new to all things object-oriented to the exciting world of ColdFusion Components. This book serves two purposes very well: Making object-orientation easy to grasp and thoroughly discussing ColdFusion components. Although it can be a quick cover-to-cover read, don't be surprised to find yourself dog-earing pages, underlining sentences, and propping it open on your desk as a reference to implementing CFCs in real applications. Bravo to Techspedition - I can't wait for the next in the series!

Summary: Covering both features and shortcomings
Comment: CFC are maybe the most important improvement coming from ColdFusion MX, bringing concepts borrowed from OOP to CFML. This book digs deep into CFC, covering both their great features and their shortcomings and it even uncovers a few bugs along the way. The author's main targets are developers used to CFML and procedural programming that need to get acquainted with the new, OOP-like, paradigm introduced by CFC. Still, seasoned OOP programmers may benefit from it as well, since CFC implementation diverges in many ways from many traditional OOP concepts. Compared to other books of similar size it can be a little overprized, but you should consider Techspedition is a very small, independent, publisher that really deserve our support
