Making the Connection Cache closable?

[Christofer Dutz <ch...@c-ware.de>]

Hi all,

I recently had a discussion with our friends from StreamPipes and they were having problems that they couldn’t force closing of a connection in the connection-pool.
The use case they described was that the configuration of the connection was changed, but the old connection stayed alive.

I proposed adding a close() method to the connection-cache that shuts down the connection cache and all connections it currently manages.

If nobody objects within the next few hours, this is what I’ll be working on this week’s PLC4X-Friday-Afternoon.

Hi,

I was also thinking, if it would make sense to make the normal PlcConnectionManager (which was already pointed out is more of a PlcConnectionFactory, as it doesn’t manage the connection after being created)
more a “manager”. So, it should keep references to the connections it created and be able to close them by closing the PlcConnectionManager instance.

+1 that is really a useful and needed feature.
