Object Calisthenics


Object Calisthenics is an idea suggest by Jeff Bay in The ThoughtWorks Anthology , and lists 9 rules to writing better Object Oriented code. For those who haven’t seen the book, the 9 rules are:

# Use only one level of indentation per method
# Don’t use the else keyword
# Wrap all primitives and strings
# Use only one dot per line
# Don’t abbreviate
# Keep all entities small
# Don’t use any classes with more than two instance variables
# Use first-class collections
# Don’t use any getters/setters/properties

criticism


Suggest use to take a fresh look of original "pattern language" - http://perl.plover.com/yak/design/ , in his opinions, it is more about separate design to difference groups than create reusable design.

Some more... http://www.relevancellc.com[..]007/5/17/design-patterns-are-code-smells http://www.codinghorror.com/blog/archives/000899.html

Some say pattern should be language feature ... http://www.codinghorror.com/blog/archives/000308.html

Closely related, there are no golden rules and silver bullet, Design Pattern can help us in some design problem and provide some design suggestion. However, we need to know what it good for and bad for

when api design rule conflict


2 best practices of API design confilct each other, and how to find out the solution - http://martinfowler.com/bliki/ExpressionBuilder.html

What exactly simple mean? http://typo.objectmentor.com[..]s-that-pass-for-simple-i-cant-understand . In my opinions, a more concrete interpretation of simple is first define what is most important to you, then find the quickest way to get there.

Iceberg Classes, if encapsulation is good, how about having more private method? Or actually the logic should be split? - http://www.artima.com/weblogs/viewpost.jsp?thread=125574
