Class Description

                                                                      
 TProofPlayer

~TProofPlayerRemote()

 Destructor.

Long64_t Process(TDSet *dset, const char *selector_file, Option_t *option, Long64_t nentries, Long64_t first, TEventList * /*evl*/)

{
 Process specified TDSet on PROOF. This method runs on a master.
 Returns -1 in case error, 0 otherwise.

Long64_t Finalize(Bool_t force, Bool_t sync)

 Finalize a query.
 Returns -1 in case error, 0 otherwise.

Long64_t Finalize(TQueryResult *qr)

 Finalize the results of a query already processed.

Bool_t SendSelector(const char* selector_file)

 Send the selector file(s) to master or worker nodes.

void MergeOutput()

 Merge objects in output the lists.

void Progress(Long64_t total, Long64_t processed)

 Progress signal.

void Feedback(TList *objs)

 Feedback signal.

void StopProcess(Bool_t abort, Int_t)

 Stop process after this event.

void StoreOutput(TList *out)

 Store received output list.

TList * MergeFeedback()

 Merge feedback lists.

void StoreFeedback(TObject *slave, TList *out)

 Store feedback results from the specified slave.

void SetupFeedback()

 Setup reporting of feedback objects.

void StopFeedback()

 Stop reporting of feedback objects.

Bool_t HandleTimer(TTimer *)

 Send feedback objects to client.

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

 Get next packet for specified slave.

Bool_t IsClient()

 Is the player running on the client?

Long64_t DrawSelect(TDSet *set, const char *varexp, const char *selection, Option_t *option, Long64_t nentries, Long64_t firstentry)

 Draw (support for TChain::Draw()).

void Progress(Long64_t total, Long64_t processed)

TProofPlayerRemote(TProof *proof = 0)

TProofPlayerRemote(proof)
