TCustomBufDataset.ClearCalcFields procedure
Clears calculated fields in the specified record buffer.
Declaration
procedure ClearCalcFields(Buffer: TRecordBuffer); overrideArguments
Buffer | Record buffer updated in the method. |
Description
ClearCalcFields is an overridden procedure used to clear calculated fields in the record buffer specified by Buffer. ClearCalcFields implements the method defined in the ancestor class. ClearCalcFields uses the value in CalcFieldsSize to determine the number of bytes written in the method. FillChar is called to store the value
#0 to the required number of bytes in Buffer at the offset specified by RecordSize.
ClearCalcFields is used in the implementation of the CalculateFields and InitRecord methods.
