fwlite::Scanner<C>, a way to inspect or plots elements of a collection C by using the StringParser.
fwlite::Scanner<C>, a way to inspect or plots elements of a collection C by using the StringParser.
The collection can be something as easy as std::vector<T>, but also some other fancy EDM collections like RefVector, RefToBaseVector and OwnVector (and probably PtrVector, but it was not tested)
If you're using something other than std::vector, you must provide the full typename, including all optional template parameters; e.g. you can't have C = edm::RefVector<reco::MuonCollection>, but you need C = edm::RefVector<vector<reco::Muon>,reco::Muon,edm::refhelper::FindUsingAdvance<vector<reco::Muon>,reco::Muon> > In order to figure out what is the correct full name for a collection in an event, open it in ROOT/FWLite, get the branch name including the trailing ".obj" (hint: Events->GetAlias("label")) usually works), and then do Events->GetBranch("xxx.obj")->GetClassName() to get something like edm::Wrapper<X>. then X is what you want to use to create the fwlite::Scanner. Don't use typedefs, they don't work.

Scan the first nmax entries of the event and print out the values of some expressions.
The cut is applied to the individual entries. To set Event-wide cuts, use addEventSelector().
The different expressions are separated by ":", unless changed using setExpressionSeparator. The title of each column is the text of the expression, unless one specifies it differently by using the notation "@label=expression"
Each row is prefixed by the event id (Run/LS/Event on Data, entry number within the file for MC) and by the index of the object within the collection. The behaviour can be changed through the setPrintFullEventId() method.
The printing will pause by default every 50 lines (see setMaxLinesToPrint() to change this) Scanning will stop after nmax events.
