Internal class steering 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().
