class TPacketizerMulti: public TVirtualPacketizer


TPacketizerMulti

This class allows to do multiple runs in the same query; each run
can be a, for example, different dataset or the same dataset with
entry list.
The multiple packetizer conatins a list of packetizers which are
processed in turn.
The bit TSelector::kNewRun is set in the TSelector object when a new
packetizer is used.

Function documentation

TPacketizerMulti(TDSet* dset, TList* slaves, Long64_t first, Long64_t num, TList* input, TProofProgressStatus* st)

 Constructor

~TPacketizerMulti()

 Destructor.

TDSetElement * GetNextPacket(TSlave* wrk, TMessage* r)

 Get next packet from the current packetizer.
 If the current packetizer is done, move to next.
 Retun null when all packetizers are done.

TVirtualPacketizer * CreatePacketizer(TDSet* dset, TList* wrks, Long64_t first, Long64_t num, TList* input, TProofProgressStatus* st)

 Create a packetizer for dataset 'dset'
 Return null on failure.
