class RooExpensiveObjectCache: public TObject



RooExpensiveObjectCache is a singleton class that serves as repository for objects that are expensive to calculate. Owners of such objects can registers these here with associated parameter values for which the object is valid, so that other instances can, at a later moment retrieve these precalculated objects

Function documentation

RooExpensiveObjectCache()
 Constructor
RooExpensiveObjectCache(const RooExpensiveObjectCache& )
 Copy constructor
~RooExpensiveObjectCache()
 Destructor.
RooExpensiveObjectCache& instance()
 Return reference to singleton instance
void cleanup()
 Static function called by RooSentinel atexit() handler to cleanup at end of program
Bool_t registerObject(const char* ownerName, const char* objectName, TObject& cacheObject, const RooArgSet& params)
 Register object associated with given name and given associated parameters with given values in cache.
 The cache will take _ownership_of_object_ and is indexed under the given name (which does not
 need to be the name of cacheObject and with given set of dependent parameters with validity for the
 current values of those parameters. It can be retrieved later by callin retrieveObject()
Bool_t registerObject(const char* ownerName, const char* objectName, TObject& cacheObject, TIterator* paramIter)
 Register object associated with given name and given associated parameters with given values in cache.
 The cache will take _ownership_of_object_ and is indexed under the given name (which does not
 need to be the name of cacheObject and with given set of dependent parameters with validity for the
 current values of those parameters. It can be retrieved later by callin retrieveObject()
const TObject* retrieveObject(const char* name, TClass* tclass, const RooArgSet& params)
 Retrieve object from cache that was registered under given name with given parameters, _if_
 current parameter values match those that were stored in the registry for this object.
 The return object is owned by the cache instance.
const TObject* getObj(Int_t uniqueID)
 Retrieve payload object of cache element with given unique ID
Bool_t clearObj(Int_t uniqueID)
 Clear cache element with given unique ID
 Retrieve payload object of cache element with given unique ID
Bool_t setObj(Int_t uniqueID, TObject* obj)
 Place new payload object in cache element with given unique ID. Cache
 will take ownership of provided object!
void clearAll()
 Clear all cache elements
void print() const
void importCacheObjects(RooExpensiveObjectCache& other, const char* ownerName, Bool_t verbose = kFALSE)
Int_t size() const
{ return _map.size() ; }
