See PhastInterpolationValues.

Private procedure SetTwoDInterpolator(const Value: TCustom2DInterpolater);

See TwoDInterpolator.

Private function DataSetChanged: boolean;

DataSetChanged returns true if FDataSet differs from the data in TPhastDataSetStorage.

Private function GetFormula: string;
 
Private procedure SetFormula(const Value: string);
 
Private procedure SetDataSet(const Value: TDataArray);
 
Public procedure InvalidateDataSet;
 
Public procedure AssignBasicProperties;
 
Public procedure Assign(const DataSet: TDataArray);

Assign copies the properties of DataSet to TPhastDataSetStorage and stores DataSet in FDataSet;

Public procedure AssignFormulasToDataSet;

AssignFormulasToDataSet copies the Formula and PhastInterpolationValues properties of TPhastDataSetStorage to DataSet.

Public procedure AssignToDataSet(out ShouldInvalidate: boolean);

AssignToDataSet copies the properties of TPhastDataSetStorage (except Formula and PhastInterpolationValues) to DataSet.

Public constructor Create;

Create creates and instance of TPhastDataSetStorage

Public destructor Destroy; override;

Destroy destroys the current instance of TPhastDataSetStorage. Do not call Destroy directly. Call Free instead.
