class AliRawReaderRoot: public AliRawReader
This is a class for reading raw data from a root file. The root file is expected to contain a tree of name "RAW" with a branch of name "rawevent" which contains objects of type AliRawVEvent. The file name and the event number are arguments of the constructor of AliRawReaderRoot.

Function documentation
AliRawReaderRoot(const char* fileName, Int_t eventNumber = -1)
create an object to read digits from the given input file for the event with the given number
const AliRawEventHeaderBase* GetEventHeader() const
Get the even header Return NULL in case of failure
UInt_t GetTimestamp() const
void SwapData(const void* inbuf, const void* outbuf, UInt_t size)
The method swaps the contents of the raw-data event header
Bool_t ReadHeader()
read a data header at the current position returns kFALSE if the data header could not be read
Bool_t ReadNextData(UChar_t*& data)
reads the next payload at the current position returns kFALSE if the data could not be read
Bool_t ReadNext(UChar_t* data, Int_t size)
reads the next block of data at the current position returns kFALSE if the data could not be read
Bool_t GotoEvent(Int_t event)
go to a particular event Uses the absolute event index inside the raw-data file
AliRawReader* CloneSingleEvent() const
Clones the current event and creates raw-reader for the cloned event Can be used in order to make asynchronious access to the current raw data within several threads (online event display/reco)
