[Eap-features] Re: Refactory: Replace Inheritance with Delegation

[Jacques Morel]

Of course! How did I miss this one?

My most wnated refactoring list is 

1. Extract Class/Inline Class
   http://www.refactoring.com/catalog/extractClass.html / http://www.refactoring.com/catalog/inlineClass.html
2. Move method
   http://www.refactoring.com/catalog/moveMethod.html
3. Replace Inheritance with Delegation
   http://www.refactoring.com/catalog/replaceInheritanceWithDelegation.html
4. Replace Constructor with Factory Method
   http://www.refactoring.com/catalog/replaceConstructorWithFactoryMethod.html
   This would replace all new XXX() by XXX.newInstance().

My nice to have

1. Encapsulate Collection (mentioned several times in other threads)
   http://www.refactoring.com/catalog/encapsulateCollection.html
2. Replace Method with Method Object
   http://www.refactoring.com/catalog/replaceMethodWithMethodObject.html
   Just in case you have a method big enough to be its own object.
3. Replace Data Value with Object
   http://www.refactoring.com/catalog/replaceDataValueWithObject.html
4. Replace Parameter with Method
