public TGo4FitParameter()

Default constructor.

public TGo4FitParameter(const char * name, const char * title, Double_t iValue)

Create TGo4FitParameter object with given name, title and initial value.

public TGo4FitParameter(const char * name, const char * title, Double_t iValue, Double_t iRangeMin, Double_t iRangeMax)

Create TGo4FitParameter object with given name, title, initial value and given range limits.

public TGo4FitParameter(const char * name, const char * title, Double_t iValue, Double_t iEpsilon)

Create TGo4FitParameter object with given name, title, initial value and given epsilon.

public TGo4FitParameter(const char * name, const char * title, Double_t iValue, Double_t iRangeMin, Double_t iRangeMax, Double_t iEpsilon)

Create TGo4FitParameter object with given name, title, initial value, given range and epsilon.

public virtual synchronized ~TGo4FitParameter()

Destroy TGo4FitParameter object.

public void ChangeEpsilon(Double_t iEpsilon)

Change epsilon value.
This is not affect on status of epsilon - if epsilon was not specified before, GetEpsilon() method still return kFALSE. Method should not used in normal program. Designed for usage in GUI.

public void ChangeRangeMax(Double_t iRangeMax)

Cahnge value of range maximum.

public void ChangeRangeMin(Double_t iRangeMin)

Change value of range minimum.

public void ClearBlocked()

Release blocking of parameter.

public void ClearEpsilon()

Set status, what epsilon is not specified.
Not affect on epsilon value, therefore after SetEpsilonUse(kTRUE) GetEpsilon() method return old epsilon value.

public void ClearRange()

Clear status, that range was psecified.
Equivalent to SetRangeUse(kFALSE).

public const Bool_t GetEpsilon(Double_t& eps)

Return value of parameter epsilon.
If epsilon was not specified (by default), return kFALSE.
Epsilon means minimum step of parameter value, which can be used during minimization process.

public const Double_t GetError()

Get value of parameter error.

public const Bool_t GetFixed()

Return status, if parameter fixed or not.

public const Bool_t GetRange(Double_t& min, Double_t& max)

Return range left (minimum) and right (maximum) values.
If range was not specified before, return kFALSE.

public Double_t GetRangeMax()

Return value of range maximum.

public Double_t GetRangeMin()

Return value of range minimum.

public const Double_t GetValue()

Return parameter value.

public void MemorizeValue()

Memorize value of parameter.

public virtual const void Print(Option_t* option)

Print TGo4FitParameter object to standard output.

public void RememberValue()

Restore value, which was previosly memorized.

protected void Reset()

public void SetBlocked()

Blocks parameter value.
This means, that parameter can not be changed during minimization routine. If parameter block, GetFixed() method returns kTRUE value.
This method is used by fitter, when parameter not fixed, but for it dependency calculation is created. Thus, it can not be changed directly by minimization routine, but changing by fitter itself.

public void SetEpsilon(Double_t iEpsilon)

Return epsilon value of parameter.

public void SetEpsilonUse(Bool_t use)

Set status, if epsilon value was specified or not.
Did not change epsilon value itself. Designed for usage in GUI.

public void SetError(Double_t iError)

Set value of parameter error.

public void SetFixed(Bool_t iFixed)

Set status of parameter fixed or not.

public void SetRange(Double_t iRangeMin, Double_t iRangeMax)

Set range minimum and maximum values.

public void SetRangeUse(Bool_t use)

Change status, is range was specified or not.
Not change range values themself. Designed for usage in GUI.

public void SetValue(Double_t iValue)

Set parameter value.
