CinJUG Meeting (Monday, July 18th) & Southern Ohio Software Symposium 2005

[Jay Zimmerman <jzimmerman@xxxxxxxxxxxxxxxxxxxx>]

Greetings,

We look forward to returning to Cincinnati this month for the July 18th 
CinJUG meeting.  Be sure and join us this coming Monday as we bring in 
Andrew Glover, co-author of "Java Testing Patterns" 
from Washington D.C. to present on Code Metrics.   In addition, we will 
be giving away a free pass to the upcoming Southern Ohio Software 
Symposium coming to Cincinnati on August 26-28th. 
Go to www.nofluffjuststuff.com/sh/2005-08-cincinnati for more details.  
Special early bird pricing is available thru 8/1/05.

Andrew will be presenting: Using Code Metrics for Targeted Code Refactoring

Abstract:
The knowledge of how to effectively spot smelly code and replace it with 
proven patterns will ultimately lead to a more stable, maintainable and 
elegant code base.  Often times, candidate code for refactoring is based 
upon a source file's smell, which its spotting can take time to acquire 
and is largely based upon subjective determinations. The proper use of 
code metrics, such as Cyclomatic Complexity, Fan-In, Fan-Out, and Depth 
of Inheritance can also facilitate the discovery of candidate code which 
is in need of refactoring.

For example, Cyclomatic Complexity is adept at spotting methods 
containing a high degree of conditional logic, which, consequently, can 
be replaced with polymorphism as elaborated in Martin Fowler's seminal 
work, Refactoring with the Replace Conditional with Polymorphism 
pattern. Additionally, excessively deep hierarchy trees create 
problematic testing targets, which can be broken out into separate 
objects with Fowler's Replace Inheritance with Delegation and Collapse 
Hierarchy patterns. Fan-In and Fan-Out are quite effective at 
pinpointing brittle code, which can be refactored into a more stable 
state with a plethora of patterns including Extract Hierarchy and 
Extract Class.

Bio:  Andrew Glover is the co-author of "Java Testing Patterns" and 
founder/CEO of Vanward Technologies, a Washington, DC, metro area 
company specializing in the construction of automated testing frameworks 
and tools, which lower software bug counts, reduce integration and 
testing times, and improve overall code stability.


I hope to see you there!

All the Best,
