Is it possible that a channel is connected to more than one bridge at a time?
No. A channel can only be in 1 bridge at a time.
This sounds like you are asking about the detail when you should be asking about the goal. If you tell us the goal we may be able to suggest a solution.
i was trying to collect which channel is connected to which bridge and use that information later. so wanted to save a map of channelid > bridgeId. if the channel is never connected to more than one channel my data structure needs to be only “map<string,string>”. if not it should be “map<string, set<string>>”.
