On the Impact of Aspect-Oriented
Programming on Object-Oriented Metrics
9th ECOOP workshop on Quantitative Approaches
in Object-Oriented Software Engineering
Glasgow, Scotland
2005/07/25

2. 2/7
Goals
n Ultimate goal
– Propose a quality model to assess aspect-oriented
program design and implementation
n Design issues with aspects
– What happens to OO programs?
– How are the metrics modified?
– Can we propose a quality model?

3. 3/7
Thought
n Is AOP a new paradigm?
(and where does AspectJ stand?)
– AOP
– AOP built on top of OOP
– OOP mixed with AOP
– OOP
(Would Gregor Kiczalès agree? J)

4. 4/7
Existing work
n Metrics for AOP
– Statically
• Zhao
– Dinamically
• SABLE
n Impact of AOP on OO metrics
– Sant’Anna
– But only aspect and advice

5. 5/7
Contributions
n Consider all AOP abstractions (as
implemented in AspectJ)
n Automate the metric computation and the
quality assessment
n Assess the impact of AOP abstractions on
design and implementation

6. 6/7
Methodology
n Relation between AOP and OOP
n Impact of AOP and OO metrics
n Study several AOP programs (and
possibly compare with their full OO
counter-parts)

7. 7/7
Questions
n Is our ultimate goal valid?
n Is our methodology valid?
n Where are the AOP programs?
