There are examples showing you:

1. Detect the places you have forgotten to write "logger.isDebugEnabled()"
2. Fix a type of misuse of logger.error() API
3. Remove unused imports

There are two extension points: FileFilter & AstFunction. Implement them and call FileWalker to run your own operations.
(github.exia.provided.JavaSourceFileFilter is ready to use, filtering *.java files)

github.exia.ast.util provides convenient utilities.
