class TProofPlayer: public TVirtualProofPlayer


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

TProofPlayer(TProof* proof = 0)
 Default ctor.
~TProofPlayer()
 Destructor.
void SetProcessing(Bool_t on = kTRUE)
 Set processing bit according to 'on'
void StopProcess(Bool_t abort, Int_t timeout = -1)
 Stop the process after this event. If timeout is positive, start
 a timer firing after timeout seconds to hard-stop time-expensive
 events.
void SetDispatchTimer(Bool_t on = kTRUE)
 Enable/disable the timer to dispatch pening events while processing.
void SetStopTimer(Bool_t on = kTRUE, Bool_t abort = kFALSE, Int_t timeout = 0)
 Enable/disable the timer to stop/abort processing.
 The 'timeout' is in seconds.
void AddQueryResult(TQueryResult* q)
 Add query result to the list, making sure that there are no
 duplicates.
void RemoveQueryResult(const char* ref)
 Remove all query result instances referenced 'ref' from
 the list of results.
TQueryResult * GetQueryResult(const char* ref)
 Get query result instances referenced 'ref' from
 the list of results.
