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: cask_loader.rb
    path of file: ./repos/brew/Library/Homebrew/cask
    
    the code of the file until where you have to start completion: require "cask/cask"
require "uri"

module Cask
  module CaskLoader
    class FromContentLoader
      attr_reader :content

      def self.can_load?(ref)
        return false unless ref.respond_to?(:to_str)

      
    
    def self.for(ref)
      [
        FromInstanceLoader,
        FromContentLoader,
        FromURILoader,
        FromTapLoader,
        FromTapPathLoader,
        FromPathLoader,
      ].each do |loader_class|
        return loader_class.new(ref) if loader_class.can_load?(ref)
      end

      if FromTapPathLoader.can_load?(default_path(ref))
        return FromTapPathLoader.new(default_path(ref))
      end
