Bool_t TTreeFormulaManager::Sync ( )
virtual
void TTreeFormulaManager::UpdateFormulaLeaves ( )
virtual

This function could be called TTreePlayer::UpdateFormulaLeaves, itself called by TChain::LoadTree when a new Tree is loaded.

Because Trees in a TChain may have a different list of leaves, one must update the leaves numbers in the TTreeFormula used by the TreePlayer.
