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: lines_classifier.rb
    path of file: ./repos/simplecov/lib/simplecov
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module SimpleCov
  # Classifies whether lines are relevant for code coverage analysis.
  # Comments & whitespace lines, and :nocov: token 
    
    def classify(lines)
      skipping = false

      lines.map do |line|
        if self.class.no_cov_line?(line)
          skipping = !skipping
          NOT_RELEVANT
        elsif skipping || self.class.whitespace_line?(line)
          NOT_RELEVANT
        else
          RELEVANT
        end
      end
