Refactoring is the process of making changes to the internal structure of existing code without changing the external behavior of that code, The resulting code is more flexible, reusable, and maintainable. While refactoring is becoming more popular in the software development community, manual refactoring can be a long and tedious process. Tools that support refactoring are becoming available; however, many provide only limited types of refactorings and require heavy user intervention. This paper presents an open source framework for an adaptive refactoring tool. The framework allows easy addition of new refactorings or modification of existing ones. An implementation of the framework is described in this paper.
