Description

Clears the lookup and calculated fields.

FireDAC.Comp.DataSet.TFDDataSet.ClearCalcFields inherits from Data.DB.TDataSet.ClearCalcFields. All content below this line refers to Data.DB.TDataSet.ClearCalcFields.

Clears the lookup and calculated fields.

ClearCalcFields is used to clear the lookup and the calculated fields for the Buffer record buffer. The method is blank, so every TDataSet descendant must override it in a specific way.
