Class Description

                                                                      
 TPacketizer                                                          
                                                                      
 This class generates packets to be processed on PROOF slave servers. 
 A packet is an event range (begin entry and number of entries) or    
 object range (first object and number of objects) in a TTree         
 (entries) or a directory (objects) in a file.                        
 Packets are generated taking into account the performance of the     
 remote machine, the time it took to process a previous packet on     
 the remote machine, the locality of the database files, etc.
TPacketizer(TDSet *dset, TList *slaves, Long64_t first, Long64_t num, TList *input)
 Constructor
~TPacketizer()
 Destructor.
void RemoveUnAllocNode(TFileNode * node)
 Remove unallocated node.
void RemoveActive(TFileStat *file)
 Remove file from the list of actives.
void RemoveActiveNode(TFileNode *node)
 Remove node from the list of actives.
void Reset()
 Reset the internal datastructure for packet distribution.
void ValidateFiles(TDSet *dset, TList *slaves)
 Check existence of file/dir/tree an get number of entries.
 Assumes the files have been setup.
void SplitEventList(TDSet *dset)
 Splits the eventlist into parts for each file.
 Each part is assigned to the apropriate TDSetElement.
Long64_t GetEntriesProcessed(TSlave *slave)
 Get entries processed by the specified slave.
TDSetElement* CreateNewPacket(TDSetElement* base, Long64_t first, Long64_t num)
 Creates a new TDSetElement from from base packet starting from first entry with num entries.
 The function returns a new created objects which have to be deleted.
TDSetElement * GetNextPacket(TSlave *sl, TMessage *r)
 Get next packet
Bool_t HandleTimer(TTimer *)
 Send progress message to client.
