Defined in:
lib/rubocop/cop/lint/ineffective_access_modifier.rb

Overview

This cop checks for `private` or `protected` access modifiers which are applied to a singleton method. These access modifiers do not make singleton methods private/protected. `private_class_method` can be used for that.

Examples:


# bad

class C
  private

  def self.method
    puts 'hi'
  end
end

# good

class C
  def self.method
    puts 'hi'
  end

  private_class_method :method
end

# good

class C
  class << self
    private

    def method
      puts 'hi'
    end
  end
end
