    module Agents class TwitterFavorites < Agent include TwitterConcern cannot_receive_events! description <<-MD The Twitter Favorites List Agent follows the favorites list of a specified Twitter user. #{twitter_dependencies_missing if dependencies_missing?} To be able to use this Agent you need to authenticate with Twitter in the [Services](/services) section first. You must also provide the `username` of the Twitter user, `number` of latest tweets to monitor and `history' as number of tweets that will be held in memory. Set `expected_update_period_in_days` to the maximum amount of time that you'd expect to pass between Events being created by this Agent. Set `starting_at` to the date/time (eg. `Mon Jun 02 00:38:12 +0000 2014`) you want to start receiving tweets from (default: agent's `created_at`) MD event_description <<-MD Events are the raw JSON provided by the [Twitter API](https://dev.twitter.com/docs/api/1.1/get/favorites/list).
