TTreeIndex::TTreeIndex | ( | const TTree * | T, |
const char * | majorname, | ||

) |
Normal constructor for TTreeIndex.
Build an index table using the leaves of Tree T with major & minor names The index is built with the expressions given in "majorname" and "minorname".
a Long64_t array fIndexValues is built with:
This array is sorted. The sorted fIndex[i] contains the serial number in the Tree corresponding to the pair "major,minor" in fIndexvalues[i].
Once the index is computed, one can retrieve one entry via
Example:
Note that majorname and minorname may be expressions using original Tree variables eg: "run-90000", "event +3*xx". However the result must be integer.
In case an expression is specified, the equivalent expression must be computed when calling GetEntryWithIndex.
To build an index with only majorname, specify minorname="0" (default)
Assuming a parent Tree T and a friend Tree TF, the following cases are supported:
Once the index is built, it can be saved with the TTree object with tree.Write(); (if the file has been open in "update" mode).
The most convenient place to create the index is at the end of the filling process just before saving the Tree header. If a previous index was computed, it is redefined by this new call.
Note that this function can also be applied to a TChain.
The return value is the number of entries in the Index (< 0 indicates failure)
It is possible to play with different TreeIndex in the same Tree. see comments in TTree::SetTreeIndex.

Returns the entry number in this (friend) Tree corresponding to entry in the master Tree 'parent'.

Return entry number corresponding to major and minor number.
Note that this function returns only the entry number, not the data To read the data corresponding to an entry number, use TTree::GetEntryWithIndex the BuildIndex function has created a table of Double_t* of sorted values corresponding to val = major<<31 + minor; The function performs binary search in this sorted table. If it finds a pair that maches val, it returns directly the index in the table. If an entry corresponding to major and minor is not found, the function returns the index of the major,minor pair immediately lower than the requested value, ie it will return -1 if the pair is lower than the first entry in the index.
