22Template class RooCacheManager manages the storage of any type of data indexed on
23the choice of normalization and optionally the set of integrated observables.
24The purpose of this class is to faciliate storage of intermediate results
25in operator p.d.f.s whose value and inner working are often highly dependent
26on the user provided choice of normalization in getVal().
27
28For efficiency reasons these normalization set pointer are
29derefenced as little as possible. This class contains a lookup
30table for RooArgSet pointer pairs -> normalization lists. Distinct
31pointer pairs that represent the same normalization/projection are
32recognized and will all point to the same normalization list. Lists
33for up to 'maxSize' different normalization/ projection
34configurations can be cached.
