OpenChannelHandler

public interface OpenChannelHandler

Open channel event handler.

Listens for all open channel event notifications in a unified manner, including:

Operations: entering, entered, enter failure, exited, reset, and channel destruction
Notifications: multi-device login sync, member ban/unban, and member mute/unmute
Metadata: KV data sync after joining, and incremental KV changes (update/delete)
Members: member join/leave changes with updated total count

Register via NCEngine.addOpenChannelHandler. All callback methods have default empty implementations; override only the callbacks you need.
