StreamGroup<T> class

A collection of streams whose events are unified and sent through a central stream.

Both errors and data events are forwarded through stream. The streams in the group won't be listened to until stream has a listener. Note that this means that events emitted by broadcast streams will be dropped until stream has a listener.

If the StreamGroup is constructed using new StreamGroup, stream will be single-subscription. In this case, if stream is paused or canceled, all streams in the group will likewise be paused or canceled, respectively.

If the StreamGroup is constructed using new StreamGroup.broadcast, stream will be a broadcast stream. In this case, the streams in the group will never be paused and single-subscription streams in the group will never be canceled. Note that single-subscription streams in a broadcast group may drop events if a listener is added and later removed. Broadcast streams in the group will be canceled once stream has no listeners, and will be listened to again once stream has listeners.

stream won't close until close is called on the group and every stream in the group closes.
