void TTreeProcessor::Process | ( | std::function< void(TTreeReader &)> | func | ) |
Process the entries of a TTree in parallel.
The user-provided function receives a TTreeReader which can be used to iterate on a subrange of entries
The user needs to be aware that each of the subranges can potentially be processed in parallel. This means that the code of the user function should be thread safe.
[in] | func | User-defined function that processes a subrange of entries |
