Re: Class level Refactorings

Dear Adam Sroka,

Thanks for your informative reply. I went through the Refactoring Catalogue and 
also read some papers. I found the below list of refactoring, which can apply at 
the level of class diagram. 


Extract Class
Inline Class
Move attribute
Pullup attribute 
Pushdown Attribute
Move Method
Pullup Method
Pushdown Method
Extract super Class
Collapse Heirarchy
Extract Subclass
Replace Inheritance with delegation
Replace delegation with inheritance

I was wondering that how much in detailed, i will need the Class model in order 
to apply the above mentioned refactorings.
I will really apprecaite, if you could me some suggections.

Subject: Re: [refactoring] Class level Refactorings

Some refactorings are internal to the class, meaning that the structure
represented in a UML diagram wouldn't change (maybe just the names of some
things changed.) Other refactorings might move members from one class to
another or up or down the inheritance hierarchy. Or, they could introduce
new classes or eliminate a class and move its members to other classes.

Many of the refactorings described in Martin Fowler's book had UML class
diagrams depicting their structure. Some of these are reproduced online (
http://refactoring.com/catalog/index.html).

However, the point of refactoring is to create structural changes that are
behavior preserving. There isn't really any way to tell from a class diagram
that behavior has or has not been preserved. You need to see the code to
figure out whether it was really refactoring or some other structural
change.
