on Received
Receives real-time or offline messages.
Note: 1. For offline messages, the server packages 200 messages into a single bundle and sends it to the client, which then parses the bundle. 2. `hasPackage` indicates whether there are remaining message bundles, and `left` indicates how many messages are left in the current bundle after parsing and delivering them to the app layer. How to determine if all offline messages have been received: 1. Both `hasPackage` and `left` are 0; 2. `hasPackage` being 0 indicates that the client is receiving the last bundle (200 messages), and `left` being 0 indicates that the last message in the final bundle has been received.
Return
Whether the message was processed. Returns true
if the app processed the message; otherwise, returns false
for the SDK to handle.
Parameters
The received message object.
When the client successfully connects, the server sends all compensation messages in bundles, with a maximum of 200 messages per bundle (i.e., a Package). After receiving the bundle, the client parses it and notifies the app. `left` represents the number of remaining messages in the current bundle (Package).
Indicates whether there are undelivered message bundles on the server.
Indicates whether the message is an offline message.
