DocumentationComment

Defined in:

lib/rubocop/cop/style/documentation.rb

Overview

This cop checks for missing top-level documentation of classes and modules. Classes with no body are exempt from the check and so are namespace modules - modules that have nothing in their bodies except classes, other modules, or constant definitions.

The documentation requirement is annulled if the class or module has a “#:nodoc:” comment next to it. Likewise, “#:nodoc: all” does the same for all its children.

Constant Summary

'Missing top-level %s documentation comment.'.freeze
