    Metadata details:
    filename: providers.rb
    path of file: ./repos/ruby-oembed/lib/oembed
    
    the code of the file until where you have to start completion: require 'rubygems'
require 'yaml'

module O
    
      def set_access_tokens(access_tokens)
        access_tokens.each do |token_name, token_value|
          token_name = token_name.to_sym
          next unless @@access_token_setters.has_key?(token_name)

          @@access_token_setters[token_name].each do |token_setter_method|
            token_setter_method.call(token_value)
