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: definition.rb
    path of file: ./repos/factory_bot/lib/factory_bot
    
    the code of the file until where you have to start completion: module FactoryBot
  # @api private
  class Definition
    attr_reader :defined_traits, :declarations, :name, :registered_enums
    attr_accessor :klass

    def initialize(name, base_traits = [])
      @name = name
      @declarations = DeclarationList.new(name)
      @callbacks = []
      @defined_traits = Set.new
      @registered_enums = []
      @to_create = nil
      @base_traits = ba
    
    def compile(klass = nil)
      unless @compiled
        expand_enum_traits(klass) unless klass.nil?

        declarations.attributes

        self.klass ||= klass
        defined_traits.each do |defined_trait|
          defined_trait.klass ||= klass
          base_traits.each { |bt| bt.define_trait defined_trait }
          additional_traits.each { |at| at.define_trait defined_trait }
        end

        @compiled = true

        ActiveSupport::Notifications.instrument "factory_bot.compile_factory", {
          name: name,
          attributes: declarations.attributes,
          traits: defined_traits,
          class: klass || self.klass
        }
      end
