Overview

A message sent and received over the Realtime protocol. A ProtocolMessage always relates to a single channel only, but can contain multiple individual Messages or PresenceMessages. ProtocolMessages are serially numbered on a connection. See the / Ably client library developer documentation for further details on the members of a ProtocolMessage
