This should only be called on update cursors. The cursor must be initialized to a row (with the NextRow method) before this method can be successfully called. Specified by: updateRow in interface ICursor Parameters: row - A reference to a .IRow (in)ĪutomationException Delete the existing Row in the database corresponding to the current position of the cursor. This method should only be called on update cursors. Specified by: nextRow in interface ICursor Returns: A reference to a .IRow Throws: IOException - If there are interop problems.ĪutomationException Update the existing Row in the database corresponding to the current position of the cursor. If no rows remain in the result set, this method returns a null value. To retrieve all rows in a result set containing N rows, the application must make N calls to NextRow. The row object returned is allocated and hydrated by the cursor, and a reference to it is handed to the application. The NextRow method on a search or update cursor returns the next row in the result set to the application. Specified by: getFields in interface ICursor Specified by: getFields in interface IFeatureCursor Returns: A reference to a .IFields Throws: IOException - If there are interop problems.ĪutomationException Advance the position of the cursor by one and return the Row object at that position.
