Function documentation

AliESDInputHandler()

 default constructor

~AliESDInputHandler()

  destructor

AliESDInputHandler(const char* name, const char* title)

 Constructor

Bool_t Init(TTree* tree, Option_t* opt)

 Initialisation necessary for each new tree

Bool_t BeginEvent(Long64_t entry)

void CheckSelectionMask()

 This method can be called by a task only if IsUserCallSelectionMask is true.

void ConnectFriends()

 Connect the friends tree as soon as available.

 Handle the friends first

Bool_t FinishEvent()

 Finish the event

Bool_t Notify(const char* path)

 Notify a directory change

Option_t * GetDataType() const

 Returns handled data type.

Int_t GetNEventAcceptedInFile()

 Get number of events in file accepted by the tag cuts
 return -1 if no info is available

Int_t GetNEventRejectedInFile()

 Get number of events in file rejected by the tag cuts
 return -1 if no info is available

Bool_t GetCutSummaryForChain(Int_t* aTotal, Int_t* aAccepted, Int_t* aRejected)

 Get number of events in the full chain
 Count accepted and rejected events
 return kFALSE if no info is available

Int_t GetNFilesEmpty()

 Count number of files in which all events were de-selected
 For such files Notify() will NOT be called
 return -1 if no info is available

TObject * GetStatistics(Option_t* option = "") const

 Get the statistics histogram(s) from the physics selection object. This
 should be called during FinishTaskOutput(). Option can be empty (default
 statistics histogram) or BIN0.

void CreatePIDResponse(Bool_t isMC = kFALSE)

 create the pid response object if it does not exist yet

AliESDInputHandler()

{return fRunTag;}

const AliEventTag * GetEventTag() const

 Get the statistics object (currently TH2). Option can be BIN0.

{return fEventTag;}

AliPIDResponse* GetPIDResponse()

PID response

{return (AliPIDResponse*)fESDpid;}

AliESDpid * GetESDpid() const

{return fESDpid;}

void SetESDpid(AliESDpid* pid)

{Changed(); fESDpid = pid;}

AliVfriendEvent* GetVfriendEvent() const

HLT

{return fFriend;}
