Constructor Details

#initialize(options = {}) ⇒ Errata

Arguments

  • 'responder' (required) - normally you pass this something like Guru.new, which should respond to questions like #is_a_bentley?. If you pass a string, it will be lazily constantized and a new object initialized from it; for example, ‘Guru’ will lead to ‘Guru’.constantize.new.

  • 'table' - takes something that acts like a RemoteTable

If and only if you don’t pass 'table', all other options will be passed to a new RemoteTable (for example, 'url', etc.)
