class AliFileMerger: public TNamed
marian.ivanov@cern.ch
Utilities for file merging.
Additional functionality on top of the standard TFileMerger:
1. Possibility to Set the reject/accept list.
1.a) Only entries selected in accept list are merged. By default all entries are selected
use AddAccept 0 to specify your desired entry
1.b) Entries selected in reject list are not merged. By default the reject list is empty.
2. syswatch.log is created diring mergin procedure.
Memeory consumption - for reading and for merging can be monitored

Function documentation
void IterAlien(const char* outputDir, const char* outputFileName = "CalibObjects.root", const char* pattern = "AliESDfriends_v1.root", Bool_t dontOverwrite = kFALSE)
void IterList(const TList* namesList, const char* outputFileName, Bool_t dontOverwrite = kFALSE)
merge in steps or in one go
void StoreResults(TObjArray* array, const char* outputFileName)
Storing the results in one single file
void StoreSeparateResults(TObjArray* array, const char* outputFileName)
Store the results in separate files (one per object)
Bool_t IsAccepted(TString name)
Accept/reject logic name - name of the entry if fAcceptMask specified - entry has to be in list of selected if fRejectMask speciefied - entry with name speciief in the list are rejected
Bool_t IsRejected(TString name)
check is the name is explicitly in the rejection list if fRejectMask speciefied - entry with name speciief in the list are rejected
void AddReject(const char* reject)
add reject string to the list of entries to be rejected for merging
void AddAccept(const char* accept)
add reject string to the list of entries to be rejected for merging
int MergeRootfile(TDirectory* target, TList* sourceNames, Bool_t nameFiltering = kTRUE)
Merge all objects in a directory modified version of root's hadd.cxx
int OpenNextChunks(const TList* namesList, TList* filesList, Int_t from, Int_t to)
int AddFile(TList* sourcelist, string entry)
add a new file to the list of files static int count(0);
