Class Description

 The TBrDigitizeDC is the base module for digitization of drift
  Chambers. The algorithms are based on those in Sonata and Sonata++

BrDigitizeDC() :BrModule()

BrDigitizeDC(const Char_t *Name, const Char_t *Title) :BrModule(Name,Title)

void DefineHistograms()

 Called from Module::Book

 Create histograms

void SetDetectorParamsDC(BrDetectorParamsDC* par)

 Set the DC parameters with the values of the external parameters
 referenced by pointer
 Note that no owner ship is transferred. A copy is made.

void SetDetectorParamsDC(const BrDetectorParamsDC& par)

 Set the TPC parameters with the values of the external parameters.
 Note that no owner ship is transferred. A copy is made.
 There is no real need for the copy code here. Both Name and Title
 will be copied (it seems)

void ListDetectorParameters() const

 List the current value of the digitization parameters on
 standard out.

void SetDetectorVolume(BrDetectorVolume *vol)

BrDetectorVolume* GetDetectorVolume(const Char_t *name)

void ListEventStatistics()

~BrDigitizeDC()

 Is there a problem with the fact the the fParams_p can point to different kinds
 of datastructures i.e. potential memory leak. probably yes since fParams_p is
 defined as BrDetectorParams nor BrDetectorParamsTPC.
 By second thought it is probably ok. As long as all parameters are defined/set
 Using the SetDetectorParamsTPC / DC /BB etc..

void Init()

 The init member function/method is used to define histograms
 The histograms is added to the list of hist objects in this
 module.

void Event(BrEventNode* InputTable,BrEventNode* OutputTable) // Event method for DC digitization //

Bool_t Digitize(BrEventNode* InputTable,BrEventNode* OutputTable)

Digitize DC events
return kTRUE if successful
return kFALSE if error

void SetDetectorTrackParams(BrGeantHit* hit)

 define track associated with a hit in the local detector frame

void SetSubModuleTrackParams(BrGeantHit* hit)

 define track associated with a hit in the local sub-module frame

void SortDighit(BrDataTable* DigitizedHits)

void DrawGeantHits()
