RooAbsCachedReal Class Reference

Abstract base class for functions that need or want to cache their evaluate() output in a RooHistFunc defined in terms of the used observables.

This base class manages the creation and storage of all RooHistFunc cache p.d.fs and the RooDataHists that define their shape. Implementations of RooAbsCachedReal must define member function fillCacheObject() which serves to fill an already created RooDataHist with the functions function values. In addition the member functions actualObservables() and actualParameters() must be define which report what the actual observables to be cached are for a given set of observables passed by the user to getVal() and on which parameters need to be tracked for changes to trigger a refilling of the cache histogram.
