public abstract class Lint
extends Registration

Lint is a quick Java code-checker.

Currently it checks only two things:

• Uses of Label.toString() (which should almost always be Label.name instead), and
• Testing objects for equality using == (instead of equals()).

Invoke with:

 java harpoon.Main.Lint [package1] [package2] ...
 

Output is a list of source files and line numbers which are being flagged as possibly incorrect.
