Defined in:
lib/rapporteur/check_list.rb

Overview

Manages a list of checks.

The goals of this object are to store and return the check objects given to it in the same order they were given (in Ruby 1.8 and newer). And, to ensure that the same check is not added twice to be run.

Previously, a native Ruby Set was used. However, Sets do not guarantee order, particularly in Ruby 1.8. A simple Array is possible, but loses the uniqueness constraint of the objects added.
