Checker Framework provides a collection of type systems to prevent bugs on Java programs at development time. Although a type system might be useful to prevent certain types of errors, it requires the effort to write all the types, which might be an annoying task for developers. In order to tackle such problem, developers might use a type inference tool to write the types for a program. Particularly, to determine what type should be written for a procedure’s formal parameter, a type inference tool must examine the type of the argument at every call to that procedure. Thus, the type inference process requires a whole-program analysis. In conclusion, the main goal of this project is to create a single type inference tool that will work for any type system available in Checker Framework (e.g., Nullness and Interning Checker).
