Dear Rooters,
I have the following question, working in Root 5.22.
I am trying to fill and read back a std::vector< std::vector >
The filling and manual reading back (analog to the hvector.C tutorial) works without a problem, but as I would like to perform selections on the tree, I would like to make selections on elements of the inner vector, i.e. for each vector->at(i) I would like to say something like vector->at(i).at(0) > 10 (or similar) within the tree->Draw() command.
Is this possible and if so, how?
Any ideas appreciated.
Cheers,
Erik
