struct CollectionBranches
- #include <podio/utilities/RootHelpers.h>
Small helper struct to collect all branches that are necessary to read or write a collection.
Needed to cache the branch pointers and avoid having to get them from a TTree/TChain for every event.

-
std::vector<TBranch*> vecs = {}
-
std::vector<std::string> refNames = {}
The names of the relation branches.
-

inline auto keysPtr()
Get a pointer to the stored keys for binding it to a TBranch.
-
inline auto valuesPtr()
Get a pointer to the stored vectors for binding it to a TBranch.
