Member Data Documentation

fFriendChainSubNames

std::vector<std::vector<std::string> > ROOT::Internal::TreeUtils::RFriendInfo::fFriendChainSubNames

Names of the subtrees of a friend TChain.

fFriendChainSubNames[i] is the list of names of the trees that make a friend TChain whose information is stored at fFriendNames[i] and fFriendFileNames[i]. If instead the friend tree at position i is a TTree, fFriendChainSubNames[i] will be just a vector with a single empty string.

Definition at line 57 of file InternalTreeUtils.hxx.

fFriendFileNames

std::vector<std::vector<std::string> > ROOT::Internal::TreeUtils::RFriendInfo::fFriendFileNames

Names of the files where each friend is stored.

fFriendFileNames[i] is the list of files for friend with name fFriendNames[i].

Definition at line 49 of file InternalTreeUtils.hxx.

fFriendNames

std::vector<NameAlias> ROOT::Internal::TreeUtils::RFriendInfo::fFriendNames

Pairs of names and aliases of friend trees/chains.
