TChainIndex A Chain Index with majorname and minorname. It uses tree indices of all the trees in the chain instead of building a new index. The index values from the first tree should be less then all the index values from the second tree, and so on. If a tree in the chain doesn't have an index the index will be created and kept inside this chain index.
Long64_t | fMaxIndexValue | the maximum value of the index |
Long64_t | fMinIndexValue | the minimum value of the index |
TVirtualIndex* | fTreeIndex | the tree index in case it was created in the constructor, |
