Progress
Done:
- Examination of the refactoring tool by Chris Seguin
- Overview of the AST & the Java Grammer file for JavaCC and JJTree
- Tree view of the AST of a method from the UI
- Source view of a method
- Select statements view of a method (not finished yet)
To do:
- Check the role and scope of variables
- Create the parameter list of the method
- Check if the method should return a value and the type of this value.
- Create a new method
- Remove the statements from the parent method
Testing
Maybe we could accept the example refactoring in the refactoring book of Martin Fowler as a test case. We could devide it into several test cases.

Ideas
- Make method extraction possible. Maybe we should extend the grammar for this.
- You should be able to view the code of a method from the uml view. The pretty printer should be used for this. This feature can be used for code selection in the extract method refactoring.
- Variable information (currently not supported): references should know what the type of the variable is and where it is defined etc.
- Editing information: is a variable in a piece of code used for reading or also for writing purposes?
Other ideas which could be used to write a new tool:
- Create a tool which supports safe refactoring by warning for any possible error which could occure. It should always create correct Java code or it should warn if this isn't possible.
- Refactorings should be as small and reusable as possible to make it easy to add refactorings.
- Make a very good parse tree which can be used for many refactorings and other program elements:
- Checking methods should be included in the parse tree to make them reusable for other refactorings.
- Methods should know where they are called to make refactorings efficient and easy.
- Classes should know where they are referenced so they can warn that items when classnames or other classitems change.
- Try to use code of the Refactoring Tool by Chris Seguin when some problems are solved there in a nice way.
