Takes a potential owner - a Session, returns Sequencing object.
Note that before creating a Sequencing object there is a check performed
to determine whether the object could be created.
Sequencing sequencing = null;
if (session.isClientSession()) {
ClientSession cs = (ClientSession)session;
if (ClientSessionSequencing.sequencingServerExists(cs)) {
sequencing = new ClientSessionSequencing(cs);
}
}
return sequencing;
