class RooCachedPdf: public RooAbsCachedPdf

 Constructor taking name, title and function to be cached. To control
 granularity of the binning of the cache histogram set the desired properties
 in the binning named "cache" in the observables of the function. The dimensions
 of the cache are automatically matched to the number of observables used
 in each use context. Multiple cache in different observable may exists
 simultanously if the cached p.d.f is used with multiple observable
 configurations simultaneously

 Constructor taking name, title and function to be cached and
 fixed choice of variable to cache. To control granularity of the
 binning of the cache histogram set the desired properties in the
 binning named "cache" in the observables of the function.
 If the fixed set of cache observables does not match the observables
 defined in the use context of the p.d.f the cache is still filled
 completely. Ee.g. when it is specified to cache x and p and only x
 is a observable in the given use context the cache histogram will
 store sampled values for all values of observable x and parameter p.
 In such a mode of operation the cache will also not be recalculated
 if the observable p changes

 Copy constructor

 Destructor

 Update contents of cache histogram by resampling the input p.d.f. Note that
 the cache is filled with normalized p.d.f values so that the RooHistPdf
 that represents the cache contents can be explicitly declared as self normalized
 eliminating the need for superfluous numeric calculations of unit normalization.s

 If this pdf is operated with a fixed set of observables, return
 the subset of the fixed observables that are actual dependents
 of the external input p.d.f. If this p.d.f is operated without
 a fixed set of cache observables, return the actual observables
 of the external input p.d.f given the choice of observables defined
 in nset

 If this p.d.f is operated with a fixed set of observables, return
 all variables of the external input p.d.f that are not one of
 the cache observables. If this p.d.f is operated in automatic mode,
 return the parameters of the external input p.d.f

 Return the base name for cache objects, in this case the name of the cached p.d.f
