00020 // Template class RooCacheManager manages the storage of any type of data indexed on
00021 // the choice of normalization and optionally the set of integrated observables.
00022 // The purpose of this class is to faciliate storage of intermediate results
00023 // in operator p.d.f.s whose value and inner working are often highly dependent
00024 // on the user provided choice of normalization in getVal(). 
00025 //
00026 // For efficiency reasons these normalization set pointer are
00027 // derefenced as little as possible. This class contains a lookup
00028 // table for RooArgSet pointer pairs -> normalization lists.  Distinct
00029 // pointer pairs that represent the same normalization/projection are
00030 // recognized and will all point to the same normalization list. Lists
00031 // for up to 'maxSize' different normalization/ projection
00032 // configurations can be cached.
