Class: RuboCop::Cop::Style::StaticClass
- Includes:
- VisibilityHelp
- Defined in:
- lib/rubocop/cop/style/static_class.rb
Overview
This cop checks for places where classes with only class methods can be replaced with a module. Classes should be used only when it makes sense to create instances out of them.
This cop is marked as unsafe, because it is possible that this class is a parent for some other subclass, monkey-patched with instance methods or a dummy instance is instantiated from it somewhere.
