History

Norman Maurer 0ea4597542 Introduce CodecOutputList to reduce overhead of encoder/decoder Motivation: `99dfc9ea79` introduced some code that will more frequently try to forward messages out of the list of decoded messages to reduce latency and memory footprint. Unfortunally this has the side-effect that RecycleableArrayList.clear() will be called more often and so introduce some overhead as ArrayList will null out the array on each call. Modifications: - Introduce a CodecOutputList which allows to not null out the array until we recycle it and also allows to access internal array with extra range checks. - Add benchmark that add elements to different List implementations and clear them Result: Less overhead when decode / encode messages.
