18// TProofPlayer //
19// //
20// This internal class and its subclasses steer the processing in PROOF.//
21// Instances of the TProofPlayer class are created on the worker nodes //
22// per session and do the processing. //
23// Instances of its subclass - TProofPlayerRemote are created per each //
24// query on the master(s) and on the client. On the master(s), //
25// TProofPlayerRemote coordinate processing, check the dataset, create //
26// the packetizer and take care of merging the results of the workers. //
27// The instance on the client collects information on the input //
28// (dataset and selector), it invokes the Begin() method and finalizes //
29// the query by calling Terminate(). //
30// //
