class RooCacheManager<RooAbsCacheElement>: public RooAbsCache

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.

Function documentation

void RooCacheManager<T> reset()

 Clear the cache

void RooCacheManager<T> sterilize()

 Clear the cache payload but retain slot mapping w.r.t to
 normalization and integration sets.

Int_t RooCacheManager<T> setObj(const RooArgSet* nset, const RooArgSet* iset, RooAbsCacheElement* obj, const TNamed* isetRangeName = 0)

 Insert payload object 'obj' in cache indexed on nset,iset and isetRangeName

T* RooCacheManager<T> getObj(const RooArgSet* nset, const RooArgSet* iset, Int_t* sterileIdx = 0, const TNamed* isetRangeName = 0)

 Retrieve payload object indexed on nset,uset amd isetRangeName
 If sterileIdx is not null, it is set to the index of the sterile
 slot in cacse such a slot is recycled

T* RooCacheManager<T> getObjByIndex(Int_t index) const

 Retrieve payload object by slot index

const RooNameSet* RooCacheManager<T> nameSet1ByIndex(Int_t index) const

 Retrieve RooNameSet associated with slot at given index

const RooNameSet* RooCacheManager<T> nameSet2ByIndex(Int_t index) const

 Retrieve RooNameSet associated with slot at given index

T* getObj(const RooArgSet* nset, Int_t* sterileIndex = 0, const TNamed* isetRangeName = 0)

 Getter function without integration set

Int_t setObj(const RooArgSet* nset, RooAbsCacheElement* obj, const TNamed* isetRangeName = 0)

 Setter function without integration set

Int_t lastIndex() const

 Return index of slot used in last get or set operation

Int_t cacheSize() const

 Return size of cache

Bool_t redirectServersHook(const RooAbsCollection& , Bool_t , Bool_t , Bool_t )

 Interface function to intercept server redirects

void operModeHook()

 Interface function to intercept cache operation mode changes

void printCompactTreeHook(ostream& , const char* )

 Interface function to cache add contents to output in tree printing mode

void insertObjectHook(RooAbsCacheElement& )

 Interface function to perform post-insert operations on cached object
