Implements Serializable, Cloneable
The CustomAggOperator class is used internally as a place holder for Column values that are aggregated by using the StorageDataSet.calcAggFieldsListener event.
To aggregate Column values with the StorageDataSet.calcAggFieldsListener event, you must:
public final boolean isUpdatable()This property is used internally by other com.borland classes. You should never use this property directly.
public void add(ReadRow row, long internalRow, boolean first)This method is used internally by other com.borland classes. You should never use this method directly. This method is a "dummy" add request. The StorageDataSet.calcAggFieldsListener maintains the aggregate.
public void delete(ReadRow row, long internalRow)This method is used internally by other com.borland classes. You should never use this method directly. This method is a "dummy" delete request. The StorageDataSet.calcAggFieldsListener maintains the aggregate.
