attachChannel

attachChannel attaches the given channel counter to this client. It registers the channel locally; the server is notified by the first RefreshChannel heartbeat, which creates the session and — for a client that never called activateAsync — activates the client lazily.

The returned Deferred completing only means local registration. Server-side attach finishes asynchronously: observe ChannelEvent.Initialized/ChannelEvent.Changed or Channel.getSessionId for server state. Requires a Yorkie server >= 0.7.10.
