Class Method Details

.marshall_response(method_response) ⇒ Object

By default, just runs #to_json on the method’s response value. This can be overwritten by users who know what they are doing. The response is an array of response, content-type. If returned without a content-type, it is assumed to be application/json Finally, StringIO/IO is used to signal a response that shouldn’t be formatted as JSON, and should get a different content-type header.
