template<class T>
class RooCacheManager< T >

Template class RooCacheManager manages the storage of any type of data indexed on the choice of normalization and optionally the set of integrated observables.

The purpose of this class is to faciliate storage of intermediate results in operator p.d.f.s whose value and inner working are often highly dependent on the user provided choice of normalization in getVal().

For efficiency reasons these normalization set pointer are derefenced as little as possible. This class contains a lookup table for RooArgSet pointer pairs -> normalization lists. Distinct pointer pairs that represent the same normalization/projection are recognized and will all point to the same normalization list. Lists for up to 'maxSize' different normalization/ projection configurations can be cached.
