How to get stream ID.

Hi,

I am trying to get the stream ID of the jabber stream initiated when I
create a new connection like this :

@cl = Jabber::Client::new(@jid)
@cl.connect(host='host', port=5223)
@cl.auth_nonsasl(@password, false)

I don't see any method defined for the client object @cl which can
give me the id for underlying stream.

Any help would be appreciated.

Thanks,
Shishir
