Is the Move Method refactoring a true instance? #17

Open osmarleandro opened 3 years ago

osmarleandro commented 3 years ago

Summary

In the source code of osmarleandro/RefactoringMiner@d67f4b4 commit, I applied a single Rename Class refactoring to VariableDeclarationProvider class. RefDiff yields a single Move Method refactoring as result. Why is the Rename Class refactoring instance not detected?

Code example

Diff fragment between the commit osmarleandro/RefactoringMiner@d67f4b4 and their parent.
