Identify Non-Nullable Methods

Project Idea

We have found in a manual inspection that some null checks are unnecessary, as they check the return value of a method that always returns a non-null reference. Currently, we lack an automated procedure that decides if a method always returns a non-null reference. The goal of this project is to design and implement a static analysis tool that processes method implementations and decides if their return value is guaranteed to be non-null. The analysis can then be integrated into an IDE plugin that detects unnecessary null checks.
