17 // -- CLASS DESCRIPTION [AUX] --
18 // RooMapCatEntry is an auxilary class for RooMappedCategory and defines a
19 // a mapping. A mapping consists of a wildcard regular expression, that
20 // can be matched against the input category state label and an output
21 // category state (RooCatType), which should be assign if the match is successfull.
