#has_metadata(*args) { ... } ⇒ Object
This method is used to specify the details of a datastream. You can pass the name as the first argument and a hash of options as the second argument or you can pass the :name as a value in the args hash. Either way, name is required. Note that this method doesn’t actually execute the block, but stores it, to be executed by any the implementation of the datastream(specified as :type)
