Detailed Description

Data objects, which provides access to generic TH1 ROOT histogram.

There are several implementations of TH1 for one, two and three-dimensional histogram. All of them inherited from TH1 class and supported in TGo4FitDataHistogram object. The histogram can be assigned to TGo4FitDataHistogram object in constructor, in SetHistogram() method or in SetObject() method of fitter. Histogram may owned, or may not owned by data object. TGo4FitDataHistogram gets from histogram number of dimensions and number of bins on each axis. The first and last bins on each axis (0 and NBins+1 indexes) are excluded from data analysis. This means, that data object uses only bins, which has indexes from 1 to NBins. If no calibration objects are sets up, TGo4FitDataHistogram can uses axis values, taken from histogram itself. As axis values central position of each bin is using.

Constructor & Destructor Documentation

TGo4FitDataHistogram::TGo4FitDataHistogram (   )

Default constructor. Definition at line 24 of file TGo4FitDataHistogram.cxx.

TGo4FitDataHistogram::TGo4FitDataHistogram (  const char *  iName, TH1 *  = 0, Bool_t  iHistogramOwned = kFALSE, Bool_t  AddAmpl = kFALSE )

Creates TGo4FitDataHistogram object with provided name. Pointer on histogram (derived from TH1 class) and ownership flag can be sets up in constructor. Scaling factor for bins (amplitude) can be added. Definition at line 28 of file TGo4FitDataHistogram.cxx.

TGo4FitDataHistogram::~TGo4FitDataHistogram (   )  [virtual]

Destroys TGo4FitDataHistogram object. Definition at line 33 of file TGo4FitDataHistogram.cxx.

Member Function Documentation

TH1* TGo4FitDataHistogram::GetHistogram (   )  [inline]

Return pointer on assigned histogram. Definition at line 55 of file TGo4FitDataHistogram.h. References fxHistogram, and TGo4FitSlot::GetObject(). Referenced by TGo4FitDataHistogramIter::ReadCurrentPoint(), and TGo4FitDataHistogramIter::StartReset().

void TGo4FitDataHistogram::SetHistogram (  TH1 *  iHistogram, Bool_t  iHistogramOwned = kFALSE )

Set histogram to object. Ownership flag also can be sets up. By default histogram is not owned by object. Definition at line 36 of file TGo4FitDataHistogram.cxx. References fxHistogram, and TGo4FitSlot::SetObject(). Referenced by Example5().

TGo4FitDataIter * TGo4FitDataHistogram::MakeIter (   )  [virtual]

Create TGo4FitDataHistogramIter iterator, assosiated with given data object. Reimplemented from TGo4FitData. Definition at line 41 of file TGo4FitDataHistogram.cxx.

void TGo4FitDataHistogram::FillSlotList (  TSeqCollection *  list  )  [virtual]

Add pointer on slot, which should contains histogram, to list. Reimplemented from TGo4FitData. Definition at line 45 of file TGo4FitDataHistogram.cxx. References TGo4FitData::FillSlotList(), and fxHistogram.

void TGo4FitDataHistogram::Print (  Option_t *  option  )  const [virtual]

Print information to standard output. Reimplemented from TGo4FitData. Definition at line 50 of file TGo4FitDataHistogram.cxx. References fxHistogram, TGo4FitSlot::Print(), and TGo4FitData::Print().
