A TTree is a list of TBranches.
TObjArray * GetListOfBranches()
virtual TKey * GetKey(const char *, Short_t=9999) const
Int_t GetCompressionSettings() const
Book space in a file, create I/O buffers, to fill them, (un)compress them.
A TMemFile is like a normal TFile except that it reads and writes only from memory.
virtual const char * GetName() const
Returns name of object.
Int_t GetEntries() const
Return the number of objects in array (i.e.
TObject * At(Int_t idx) const
virtual const char * GetName() const
Returns name of object.
A TTree represents a columnar dataset.
TFile * GetCurrentFile() const
Return pointer to the current file.
TDirectory * GetDirectory() const
virtual TBranchRef * GetBranchRef() const
