RooAbsSelfCached< Base_t > Class Template Reference

template<class Base_t>
class RooAbsSelfCached< Base_t >

Abstract base class for functions whose output is cached in terms of a histogram in all observables between getVal() and evaluate().

For certain p.d.f.s that are very expensive to calculate it may be beneficial to implement them as a RooAbsSelfCached rather than a RooAbsReal/Pdf. Class RooAbsSelfCached is designed to have its interface identical to that of RooAbsReal/Pdf, so any p.d.f can make use of its caching functionality by merely switching its base class. Existing RooAbsReal/Pdf objects can also be cached a posteriori with the RooCachedReal/Pdf wrapper function that takes any RooAbsReal/Pdf object as input.
