public boolean isSingleUse() {
            return singleUse;
        }
Returns whether this connection is intended for single-use only. A
single-use connection cannot be used more than once.

After a single-use connection is used, it should be automatically
and atomically removed from any underlying data (such as with
UserData.removeConnection()).

@return
    true if this connection is intended for single-use only, false
    otherwise.
