end

.scoped_methods(&block) ⇒ Object

allows the addition of scoped methods. It’s basically a class << self wrapper mostly added to make ApiModule code more self-explanatory the @obj instance variable is set in the api_scope call. This is not very clean or anything, and I am still researching a better way to do it, but the Piwik::Site API is certainly much better to work with due to this
