class TProofPlayerRemote: public TProofPlayer


TProofPlayer

 This internal class and its subclasses steer the processing in PROOF.
Instances of the TProofPlayer class are created on the worker nodes
per session and do the processing.
Instances of its subclass - TProofPlayerRemote are created per each
query on the master(s) and on the client. On the master(s),
TProofPlayerRemote coordinate processing, check the dataset, create
the packetizer and take care of merging the results of the workers.
The instance on the client collects information on the input
(dataset and selector), it invokes the Begin() method and finalizes
the query by calling Terminate().

Function documentation

~TProofPlayerRemote()
 Destructor.
Int_t InitPacketizer(TDSet* dset, Long64_t nentries, Long64_t first, const char* defpackunit, const char* defpackdata)
 Init the packetizer
 Return 0 on success (fPacketizer is correctly initialized), -1 on failure.
Long64_t Process(TDSet* set, const char* selector, Option_t* option = "", Long64_t nentries = -1, Long64_t firstentry = 0)
 Process specified TDSet on PROOF.
 This method is called on client and on the PROOF master.
 The return value is -1 in case of an error and TSelector::GetStatus() in
 in case of success.
Bool_t MergeOutputFiles()
 Merge output in files
Long64_t Finalize(Bool_t force = kFALSE, Bool_t sync = kFALSE)
 Finalize a query.
 Returns -1 in case of an 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 Progress(Long64_t total, Long64_t processed, Long64_t bytesread, Float_t initTime, Float_t procTime, Float_t evtrti, Float_t mbrti)
 Progress signal.
void Feedback(TList* objs)
 Feedback signal.
void StopProcess(Bool_t abort, Int_t timeout = -1)
 Stop process after this event.
Int_t AddOutputObject(TObject* obj)
 Incorporate the received object 'obj' into the output list fOutput.
 The latter is created if not existing.
 This method short cuts 'StoreOutput + MergeOutput' optimizing the memory
 consumption.
 Returns -1 in case of error, 1 if the object has been merged into another
 one (so that its ownership has not been taken and can be deleted), and 0
 otherwise.
void RedirectOutput(Bool_t on = kTRUE)
 Control output redirection to TProof::fLogFileW
void AddOutput(TList* out)
 Incorporate the content of the received output list 'out' into the final
 output list fOutput. The latter is created if not existing.
 This method short cuts 'StoreOutput + MergeOutput' limiting the memory
 consumption.
Int_t Incorporate(TObject* obj, TList* out, Bool_t& merged)
 Incorporate object 'newobj' in the list 'outlist'.
 The object is merged with an object of the same name already existing in
 the list, or just added.
 The boolean merged is set to kFALSE when the object is just added to 'outlist';
 this happens if the Merge() method does not exist or if a object named as 'obj'
 is not already in the list. If the obj is not 'merged' than it should not be
 deleted, unless outlist is not owner of its objects.
 Return 0 on success, -1 on error.
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* timer)
 Send feedback objects to client.
TDSetElement * GetNextPacket(TSlave* slave, TMessage* r)
 Get next packet for specified slave.
Bool_t IsClient() const
 Is the player running on the client?
Long64_t DrawSelect(TDSet* set, const char* varexp, const char* selection, Option_t* option = "", Long64_t nentries = -1, Long64_t firstentry = 0)
 Draw (support for TChain::Draw()).
 Returns -1 in case of error or number of selected events in case of success.
void SetInitTime()
 Set init time
TVirtualPacketizer * GetPacketizer() const
{ return 0; }
void Progress(Long64_t total, Long64_t processed)
void Progress(TSlave* , Long64_t total, Long64_t processed)
{ Progress(total, processed); }
TProof * GetProof() const
{ return fProof; }
TProofPlayerRemote(TProof* proof = 0)
{ fProgressStatus = new TProofProgressStatus(); }
