TChainIndex Class Reference

A Chain Index.

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.

Constructor & Destructor Documentation

TChainIndex::TChainIndex ( )
TChainIndex::TChainIndex ( const TTree T,
const char *  majorname,
const char *  minorname 
)

Normal constructor for TChainIndex.

See TTreeIndex::TTreeIndex for the description of the parameters. The tree must be a TChain. All the index values in the first tree of the chain must be less then any index value in the second one, and so on. If any of those requirements isn't met the object becomes a zombie. If some subtrees don't have indices the indices are created and stored inside this TChainIndex.

Definition at line 63 of file TChainIndex.cxx.

TChainIndex::~TChainIndex ( )
virtual

The destructor.
