Instance Method Details

#load(input, klass = self) ⇒ Object

Load GNTP response into array of:

status  (error code or '0' for OK) 
hash of headers  (except error code and notification-callback-*)
hash of callback headers (for callback responses, otherwise {})

Note this is explicitly modeled after Rack’s interface
