class AliStream: public TNamed


 AliStream.cxx

 - store file names associated with a given stream
 - open and close files
 - return serial event number of the next event in the stream
 and the TFile pointer for a proper file

Function documentation

AliStream()

 root requires default ctor, where no new objects can be created
 do not use this ctor, it is supplied only for root needs

AliStream(const char* foldername, Option_t* optioneventfoldername)

 ctor

AliStream(const AliStream& as)

 Copy ctor

~AliStream()

 default dtor

void Copy(TObject& as) const

 Copy function

void AddFile(const char* fileName)

 stores the name of the file

Bool_t NextEventInStream()

 returns kFALSE if no more events
 returns kTRUE and the serial nr of the next event
 fCurrentFile points to the file containing offered event

void ChangeMode(Option_t* option)

 set the mode to READ or UPDATE, reopen file with the new mode
 only change from UPDATE to READ have sense in the current scheme,
 other changes are possible but not usefull

Bool_t OpenNextFile()

 Opens next file in the list

Bool_t ImportgAlice()

 Imports gAlice object from file

TString GetFileName(Int_t order) const

 returns name of the order-th file
 returns empty string if such file does not exist
 first file in the input stream is 0

const TString& GetFolderName() const

{return fEventFolderName;}

Int_t GetNInputFiles() const

{return fFileNames->GetLast()+1;}

void SetFolderName(const TString name)

{ fEventFolderName = name ; }

Int_t GetCurrentEventNumber() const

{ return fLastEventSerialNr ; }
