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: entries_v4.rb
    path of file: ./repos/devdocs/lib/docs/filters/bootstrap
    
    the code of the file until where you have to start completion: module Docs
  class Bootstrap
    class EntriesV4Filter < Docs::EntriesFilter
      def get_name
        name = at_css('.bd-content h1').content.strip
        name.remove! ' system'
        name == 'Overview' ? type : name
      end

      def get_type
        if subpath.start_with?('components')
          at_css('.bd-content h1').content.strip.prepend 'Components: '
        else
          at_css('.bd-toc-item.active > .bd-toc-link').content
        end
      end

      def additional_entries
        return [] if root_page? || subpath.start_with?('getting-started') || subpath.start_with?('migration')
        entries = []

        css('.bd-toc > ul > li > a', '.bd-toc a[href="#events"]', '.bd-toc a[href="#methods"]', '.bd-toc a[href="#triggers"]').each do |node|
          name = node.content
