This Week On Code Hoarders: Declutter Your Codebase With Aspect Oriented Programming

How many lines of code in your methods actually contribute to what that method is supposed to do? The clutter of logging, security checks, exception handling, implementing INotifyPropertyChanged and much more can be purged from your methods with Aspect Oriented Programming (AOP) techniques. In this session we will clean up an application to make it more readable, better organized and easier to maintain by using AOP tools to organize the common functionality. What are you waiting for? Come to this session and get that cruft out of your codebase.

13. @jkuemerle / www.kuemerle.com AOP Terminology
14. @jkuemerle / www.kuemerle.com AOP Terminology • Cross-Cutting Concern: required but non core functionality • Advice: the implementation of specific functionality, contained in a module • Join Point: a location to execute an aspect • Pointcut: a set of join points that defines when and where to apply aspects • Aspect: when, where and what to apply in order to accomplish AOP. The combination of the pointcut and advice.
