Detailed Description

Base class for reading in various FMD data. The class loops over all found events. For each event the specified data is read in. The class then loops over all elements of the read data, and process these with user defined code. 

    struct DigitInput : public AliFMDInput 
    { 
      DigitInput() 
      { 
         // Load digits 
         AddLoad(kDigits);
         // Make a histogram 
         fHist = new TH1F("adc", "ADC spectra", 1024, -.5, 1023.5);
      }
      // Process one digit. 
      Bool_t ProcessDigit(AliFMDDigit* d)
      { 
         fHist->Fill(d->Counts());
         return kTRUE;
      }
      // After processing all events, display spectrum
      Bool_t Finish()
      {
        fHist->Draw();
      }
      TH1F* fHist;
    };

    void AdcSpectrum()
    { 
       DigitInput di;
       di.Run();
    }
This class allows for writing small scripts, that can be compiled with AcLIC, to do all sorts of tests, quick prototyping, and so on. It has proven to be quiet useful. One can load more than one type of data in one derived class, to for example to make comparisons between hits and reconstructed points. See also the various scripts in FMD/scripts.

Member Function Documentation

virtual void AliFMDInput::AddLoad (  ETrees  tree  )  [inline, virtual]
 

Add a data type to load

Parameters:
tree Data to load

Definition at line 110 of file AliFMDInput.h.

virtual Bool_t AliFMDInput::Begin (  Int_t  event  )  [virtual]
 

Callled at the beginning of each event. If a user class overloads this member function, then this must be explicitly called.

Parameters:
event Event number
Returns:
false on error

Reimplemented in AliFMDDisplay, DrawDigitsRecs, DrawHitsDigits, DrawHitsRecs, GetMedia, and Poisson.

virtual Bool_t AliFMDInput::End (   )  [virtual]
 

Called at the end of each event.

Returns:
false on error

Reimplemented in AliFMDDisplay, and Poisson.

virtual Bool_t AliFMDInput::Event (   )  [virtual]
 

Process one event. This loops over all the loaded data. Users can overload this member function, but then it's strongly recommended to explicitly call this classes version.

Returns:
false on error

virtual Bool_t AliFMDInput::Finish (   )  [inline, virtual]
 

Called at the end of the run.

Returns:
false on error

Reimplemented in CheckAlign, DrawDigitsRecs, DrawHits, DrawHitsDigits, DrawHitsRecs, GetMedia, and Poisson.

Definition at line 137 of file AliFMDInput.h.

virtual Bool_t AliFMDInput::Init (   )  [virtual]
 

Initialize the class. If a user class overloads this member function, then this must be explicitly called

Returns:
false on error

Reimplemented in AliFMDDisplay, CheckAlign, CheckRaw, GetMedia, and Poisson.

virtual Int_t AliFMDInput::NEvents (   )  const [virtual]
 

Returns:
# of available events

virtual Bool_t AliFMDInput::ProcessDigit (  AliFMDDigit *   )  [inline, virtual]
 

Process one digit. Users should over this to process each digit.
