Detailed Description

template<typename Collection>
class fwlite::Scanner< Collection >

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.

Plot the expression 'expr' for events passing 'cut', in a histogram named 'hname'

  • If htemplate is provided it will be cloned,
  • otherwise, if "SAME" is among the draw options, it will clone "htemp" (if it's available)
  • otherwise an automatically binned histogram will be used. in the last case, gEnv->GetValue("Hist.Binning.1D.x", 100) is used for the number of bins See draw(const char *expr, const char *cut, TString drawopt, TH1 *histo) for further documentation

Fill a RooDataSet.

  • Real variables are defined just like in the scan() command; a list separated by ":" (see also setExpressionSeparator());
  • Boolean variables are defined just like cuts, and are created as RooCategory with two states: pass(1) and fail(0). For each variable, the name is taken from the expression itself, or can be specified manuall by using the notation "@name=expr" Note: the dataset contains one entry per item, irrespectively of how entries are distributed among events.

Get whatever histogram makes sense for a plot passing "SAME" in drawOpt, and call it hname Currently it won't work if the histogram of which we want to be "SAME" is not called "htemp"

void fwlite::Scanner< Collection >::scan ( const char *  exprs,
const char *  cut = "",
int  nmax = -1 
)
inline

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.

How EventSelector::AcceptEvent() decides whether to accept an event for output otherwise it is excluding the probing of A single or multiple positive and the trigger will pass if any such matching triggers are PASS or EXCEPTION[A criterion thatmatches no triggers at all is detected and causes a throw.] A single negative with an expectation of appropriate bit checking in the decision and the trigger will pass if any such matching triggers are FAIL or EXCEPTION A wildcarded negative criterion that matches more than one trigger in the trigger but the state exists so we define the behavior If all triggers are the negative crieriion will lead to accepting the event(this again matches the behavior of"!*"before the partial wildcard feature was incorporated).The per-event"cost"of each negative criterion with multiple relevant triggers is about the same as!*was in the past
