Class: RuboCop::Cop::Style::PreferredHashMethods
- Includes:
- ConfigurableEnforcedStyle
- Defined in:
- lib/rubocop/cop/style/preferred_hash_methods.rb
Overview
This cop (by default) checks for uses of methods Hash#has_key? and Hash#has_value? where it enforces Hash#key? and Hash#value? It is configurable to enforce the inverse, using ‘verbose` method names also.
