Descrizione
Problem
Sometimes code elements have no package and getPackage return nulls. This introduces null checks and surprises for new developers. https://github.com/INRIA/spoon/commit/84c84e16163ff18611f82c69d5246d642e3fed86 as seen here, package can be null.
Solution
A null object[0],[1] could improve code quality. A comparable implementation is NoSourcePosition. NoSourcePosition removed all null checks for positions and improves the code quality.
Your task
Design a null object and refactor old code. Find a solution for getSimpleName() as the empty String is reserved for default package.
The PR should include:
- Design a null object for CtPackage
- Improve already existing test code and remove unnecessary null checks
It's a good starter issue, feel free to give it a try and ping if you need help for some design decisions.
