Long parameter list is a code smell - a clue that there is a problem on your software design. To help you on this this module has been written to identify methods with long parameter list and to suggest parameters groups that could became potential object because they appear together.

Methods with long parameter list pointing to a problem with OO principles. One of the approach to solve is creating objects with the parameters that appear more together. Our goal is cluster this parameters and suggest as objects.
