Detailed Description

Who belongs to whose group, found from the states of the watched devices.

The answer of a client does not name its server and its group name is its own ("(Linked) ..."), so the members of a group are matched by the group id: the server of a client is the watched device that is a server with the same id, the clients of a server are the watched devices at the addresses it lists (and the ones that report its id as clients). Pure; built from one snapshot of the monitor.

serverOf()

String de.yaacc.yxc.YxcGroupDirectory.serverOf

(

String

udn

)

Returns

the UDN of the server of the group this client is in. Only when exactly one watched device is a server with this group id and lists this client's address: group ids can be read by anybody on the network, so a second claimant or a server that does not list the client is not believed. null otherwise.
