You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: data_clump.rb
    path of file: ./repos/reek/lib/reek/smell_detectors
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require_relative 'base_detector'

module Reek
  module SmellDetectors
    #
    # A Data Clump occurs when the same two or three items frequently
    # appear together in classes and parameter lists, or when a group
    # of instance variable names start or end with similar substrings
    
      def sniff
        clumps.map do |clump, methods|
          methods_length = methods.length
          smell_warning(
            lines: methods.map(&:line),
            message: "takes parameters #{DataClump.print_clump(clump)} " \
                     "to #{methods_length} methods",
            parameters: {
              parameters: clump.map(&:to_s),
              count:      methods_length
            })
        end
      end
