class AliRawReaderChain: public AliRawReaderRoot


 This is a class for reading raw data from a root chain.
 There are two constructors available - one from a text file containing the
 list of root raw-data files to be processed and one directly from
 TFileCollection.

Function documentation

AliRawReaderChain()

 default constructor

AliRawReaderChain(const char* fileName)

 create raw-reader objects which takes as an input a root chain
 either from the file list found in 'fileName' (IsCollection = true)
 or from entry list found in 'filename' (IsCollection = false)
 The entry-list syntax follows root convetion: filename.root/listname

AliRawReaderChain(TFileCollection* collection)

 create raw-reader objects which takes as an input a root chain
 from a root file collection

AliRawReaderChain(TChain* chain)

 create raw-reader objects which takes as an input a root chain
 from a root file collection

AliRawReaderChain(TEntryList* elist)

 create raw-reader objects which takes as an input a root chain
 from a root file collection

AliRawReaderChain(Int_t runNumber)

 create raw-reader objects which takes as an input a root chain
 with the raw-data files for a given run
 It queries alien FC in order to do that and therefore
 it needs alien API to be enabled

AliRawReaderChain(const AliRawReaderChain& rawReader)

 copy constructor

~AliRawReaderChain()

 delete objects and close root file

Bool_t NextEvent()

 go to the next event in the root file

Bool_t RewindEvents()

 go back to the beginning of the root file

Bool_t GotoEvent(Int_t event)

 go to a particular event
 Uses the absolute event index inside the
 chain with raw data

Int_t GetNumberOfEvents() const

 Get the total number of events in the chain
 of raw-data files

void SetSearchPath(const char* path = "/alice/data")

 set alien query search path

TChain* GetChain() const

{ return fChain; }

const char* GetSearchPath()

{return fgSearchPath;}
