RooMultiCatIter Class Reference

Deprecated:
RooMultiCatIter is unnecessary, since all multi category classes know how to generate their own states. Use begin() / end() and range-based for loops on instances of these classes.

RooMultiCatIter iterates over all state permutations of a list of categories. It serves as the state iterator for a RooSuperCategory or a RooMultiCategory. Since this iterator only constructs state labels and does not change the value of its input categories, it is not required that its inputs are LValues.
For cases where all inputs are LValues (such as for RooSuperCategory) the values of the input can be changes by assigning the super category the string label generated by this iterator
