Description

Fields

	`FDoneDisabled: boolean;`

	`FMainCalcThread: TMainCalcThread;`

Methods

	`constructor Create(AOwner: TComponent; AEnableBackgroundVariation: boolean; ACurveScalingEnabled: boolean); overload;`

	`destructor Destroy; override;`

	`function GetAllDone: boolean; override;`

	`function GetCurAbsMin: double; override;`

	`function GetCurMin: double; override;`
Methods implement synchronization to work in multithreading environment.

	`function GetCurMinInitialized: boolean; override;`

	`function GetCurSqrMin: double; override;`

	`procedure AbortAsyncOper;`
Sets up termination flags and waits for actual termination of the thread.

	`procedure ComputeBackgroundPointsDoneSync;`

	`procedure ComputeCurveBoundsDoneSync;`

	`procedure ComputeCurvePositionsDoneSync;`

	`procedure DestroyMainCalcThread;`
Waits for thread termination.

	`procedure Done; override;`

	`procedure DoneProcSync;`

	`procedure MinimizeDifference; override;`
Fits curves starting from given parameter set (initially or repeatedly).

	`procedure MinimizeDifferenceAgain; override;`

	`procedure MinimizeNumberOfCurves; override;`
Searches set of pattern curves fitting exprerimental data with given accuracy sequentially decreasing number of such curves.

	`procedure ShowCurMin; override;`

	`procedure ShowCurMinSync;`
TODO: methods should be implemented.

	`procedure ShowProfileSync;`

	`procedure StopAsyncOper; override;`
Sets up termination flags and returns. The method doesn't wait for actual termination of the thread.

	`procedure RecreateMainCalcThread(ATask: TThreadMethod; AAllDone: TThreadMethod);`
Suppresses calling Done.

Properties

	`property DoneDisabled: boolean read FDoneDisabled write FDoneDisabled;`
