Function documentation

TChainIndex()

 Default constructor for 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.

void Append(const TVirtualIndex* , Bool_t delaySort = kFALSE)

 add an index to this chain
 if delaySort is kFALSE (default) check if the indices of different trees are in order.

void DeleteIndices()

 Delete all the indices which were built by this object

~TChainIndex()

 The destructor.

std::pair<TVirtualIndex*, Int_t> GetSubTreeIndex(Int_t major, Int_t minor) const

 Returns a TVirtualIndex for a tree which holds the entry with the specified
 major and minor values and the number of that tree.
 If the index for that tree was created by this object it's set to the tree.
 The tree index should be later released using ReleaseSubTreeIndex();

void ReleaseSubTreeIndex(TVirtualIndex* index, Int_t treeNo) const

 Releases the tree index got using GetSubTreeIndex. If the index was
 created by this object it is removed from the current tree, so that it isn't
 deleted in its destructor.

Long64_t GetEntryNumberFriend(const TTree* parent)

 see TTreeIndex::GetEntryNumberFriend for description

Long64_t GetEntryNumberWithBestIndex(Int_t major, Int_t minor) const

 See TTreeIndex::GetEntryNumberWithBestIndex for details.

Long64_t GetEntryNumberWithIndex(Int_t major, Int_t minor) const

 Returns the entry number with given index values.
 See TTreeIndex::GetEntryNumberWithIndex for details.

TTreeFormula * GetMajorFormulaParent(const TTree* parent)

 return a pointer to the TreeFormula corresponding to the majorname in parent tree T

TTreeFormula * GetMinorFormulaParent(const TTree* parent)

 return a pointer to the TreeFormula corresponding to the minorname in parent tree T

void UpdateFormulaLeaves(const TTree* parent)

 Updates the parent formulae.
 Called by TChain::LoadTree when the parent chain changes it's tree.

void SetTree(const TTree* T)

 See TTreeIndex::SetTree.
