Protected FModel: TBaseModel;
 

Methods

Private procedure SetModel(const Value: TBaseModel);
 
Protected procedure InvalidateModel;
 
Protected procedure Clear; virtual; abstract;

Clear clears all the TCustomPhastBoundaryCollections that are part of the TCustomPhastBoundary.

Protected procedure SetScreenObject(const Value: TScreenObject); virtual;

See ScreenObject.

Protected procedure UpdateBoundaryDataSet(const DataSetName: string; var Formula: string); overload;

For boundary condition data sets that do not vary with time, UpdateBoundaryDataSet is used to set the formula to be applied to the data set for this TCustomPhastBoundary. If Formula = '', the data set specified by DataSetName will no long be affected by the ScreenObject.

Protected procedure UpdateBoundaryDataSet(const DataArray: TDataArray; var Formula: string); overload;
 
Protected procedure UpdateMixtureExpression; virtual; abstract;

UpdateMixtureExpression calls TCustomPhastBoundaryCollection.UpdateMixtureExpression for each of the TCustomPhastBoundaryCollection it owns.

Protected procedure UpdateFormulaExpression; virtual; abstract;
 
Public constructor Create(ScreenObject: TScreenObject; Model: TBaseModel);
 

Properties

Public property Model: TBaseModel read FModel write SetModel;
 
Public property ScreenObject: TScreenObject read FScreenObject write SetScreenObject;

ScreenObject is the TScreenObject that owns this TCustomPhastBoundary.
