Indicates whether the current row of this <code>StreamingRowSetImpl</code>
object has been updated.  The value returned
depends on whether this rowset can detect updates: <code>false</code>
will always be returned if it does not detect updates.

@return <code>true</code> if the row has been visibly updated
        by the owner or another and updates are detected;
        <code>false</code> otherwise
@throws SQLException if the cursor is on the insert row or not
           not on a valid row
