Categorization of Refactorings

Problem Statement : The list of refactorings has become quite long. But people don't remember long lists very well. To promote learning the different patterns, they should be categorized in some way, or perhaps, along various dimensions. As a reference we have taken the list of refactorings available at [1] and categorized them along as many different dimensions as makes sense.

Class "Changing class association" "Change Bidirectional Assn to Unidirectional" "Change Unidirectional

Assn to Bidirectional"

"Change of class structure" Collapse Hierarchy Duplicate Observed Data Extract Class Extract SubClass Extract SuperClass Inline Class "Replace Subclass with Fields" Separate Data Access Code

Addition to a class Move Field Move Method Introduce Local Extension

"Moving Class elements along the inheritance hierarchy" Pull up constructor body Pull up Field Pull up Method Push down Field Push down Method
