[1.12.2]Container questions

[Bregor]

I'm currently trying to understand the inner workings of containers, but there are some weird things i noticed:
 

• Is it possible that a container has more than one listener? As there is one container per Player spawned the listeners array doesn't fit to well in that picture. (Also there is a removeListener method, which is ClientOnly and only called from the GuiRepair and GuiContainerCreative)
• Is the detectAndSendChanges method only logical server side or both? (I got only server side calls that far).

It is intented to send changes to client, so it's effective on server only.

Thanks - as i suspected then.

 

Then there is still the question if it is possible to have more than one listener on a container.

You can add as many listeners as you want.

Is there a way to remove them on the server side? Because the removeListener method is ClientOnly.

Or is there a scenario where more than one would get added, if I don't add them myself?
