See Also:   CursorResultSet the last row returned. getNextRowCore public ExecRow getNextRowCore() throws StandardException(Code) exception:   StandardException - thrown on failure getRowLocation public RowLocation getRowLocation() throws StandardException(Code) Gets information from its source. We might want to have this take a CursorResultSet in its constructor some day, instead of doing a cast here? See Also:   CursorResultSet the row location of the current cursor row. exception:   StandardException - thrown on failure getTimeSpent public long getTimeSpent(int type)(Code) Return the total amount of time spent in this ResultSet Parameters:   type - CURRENT_RESULTSET_ONLY - time spent only in this ResultSetENTIRE_RESULTSET_TREE - time spent in this ResultSet and below. long The total amount of time spent (in milliseconds). markRowAsDeleted public void markRowAsDeleted() throws StandardException(Code) See Also:   NoPutResultSet.markRowAsDeleted openCore public void openCore() throws StandardException(Code) open a scan on the source. scan parameters are evaluated at each open, so there is probably some way of altering their values... exception:   StandardException - thrown on failure reopenCore public void reopenCore() throws StandardException(Code) reopen a scan on the table. scan parameters are evaluated at each open, so there is probably some way of altering their values... exception:   StandardException - thrown if cursor finished. updateRow public void updateRow(ExecRow row) throws StandardException(Code) See Also:   NoPutResultSet.updateRow Fields inherited
