Thing Added/Removed notification [message #1755404] Thu, 02 March 2017 22:05 Go to next message

If I have a bridge handler - is there a way to be notified when child things are added/removed?

I know there is a thingRegistry.addRegistryChangeListener - but that doesn't appear to be a public api method (Access Restriction...is not API).

What's the correct way of doing this (or do I just turn off that warning and use it anyway)?

You should not care to much about child things themselves, usually you want to know as soon as there is a handler instance up and running (which automatically happens if new child things are created anyway).

And you are informed about initialized and disposed handlers, see BridgeHandler.childHandlerInitialized() and BridgeHandler.childHandlerDisposed().

That's exactly what I needed - thanks!

Side question - I have a bridge channel that can potentially include information from a child thing channel - is it possible for the bridge to listen for state update notifications from a child?

Not directly, but as the bridge handler receives the child handler, it has a change to register itself as a listener (with some custom interface specific to your binding) on it.

Yep - that's the approach I took actually. Thanks
