TTreeReader::Iterator_t Class Reference

Iterate through the entries of a TTree.

This iterator drives the associated TTreeReader; its dereferencing (and actually even the iteration) will set the entry number represented by this iterator. It does not really represent a data element; it simply returns the entry number (or -1 once the end of the tree is reached).
