A method used to propagate changes of a resultset.
In the first notify-call the listener gets two(!)
::com::sun::star::sdbc::XResultSets and has to hold
them. The ::com::sun::star::sdbc::XResultSets are
implementations of the service ContentResultSet.
The notified new
::com::sun::star::sdbc::XResultSet will stay valid
after returning from this method. The old one will become invalid after
returning.
While in notify-call the listener is allowed to read from old and
new resultset, except in the first call, where only the new resultset
is valid.
The Listener is allowed to stay (block) this call, until he really
wants to use the new resultset. The only situation, where the listener
has to return immediately is while he disposes his broadcaster or while
he is removing himself as listener (otherwise you deadlock)!!!
