ROOT 6.10/09 Reference Guide |
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).

Iterator_t () | |
Default-initialize the iterator as "past the end". More... | |
Iterator_t (TTreeReader &reader, Long64_t entry) | |

Compare two iterators for inequality. More... | |
const Long64_t & | operator* () |
Set the entry number in the reader and return it. More... | |
const Long64_t & | operator* () const |
Iterator_t | operator++ (int) |
Increment the iterator (postfix i++). More... | |
Iterator_t & | operator++ () |
Increment the iterator (prefix ++i). More... | |
bool | operator== (const Iterator_t &lhs) const |
Compare two iterators for equality. More... | |
