void TLoopManager::CreateSlots ( unsigned int  nSlots)

Initialize all nodes of the functional graph before running the event loop.

This method loops over all filters, actions and other booked objects and calls their CreateSlots methods. It is called once per node before running the event loop. The main effect is to inform all nodes of the number of slots (i.e. workers) that will be used to perform the event loop.

void TLoopManager::InitAllNodes ( TTreeReader *  r,
unsigned int  slot 
)

Build TTreeReaderValues for all nodes.

This method loops over all filters, actions and other booked objects and calls their BuildReaderValues methods. It is called once per node per slot, before running the event loop. It also informs each node of the TTreeReader that a particular slot will be using.
