Indicates whether a row has been deleted.  A deleted row may leave
a visible "hole" in a result set.  This method can be used to
detect holes in a result set.  The value returned depends on whether
or not this rowset's <code>ResultSet</code> object can detect deletions.

@return <code>true</code> if a row was deleted and deletions are detected;
<code>false</code> otherwise
@throws SQLException if a database access error occurs
           or this rowset does not currently have a valid connection,
           prepared statement, and result set
