Class RooObjCacheManager is an implementation of class RooCacheManager<RooAbsCacheElement> and specializes in the storage of cache elements that contain RooAbsArg objects.

Caches with RooAbsArg derived payload require special care as server redirects cache operation mode changes and constant term optimization calls may need to be forwarded to such cache payload. This cache manager takes care of all these operations by forwarding these calls to the RooAbsCacheElement interface functions, which have a sensible default implementation.

Constructor & Destructor Documentation

◆ RooObjCacheManager() [1/2]

RooObjCacheManager::RooObjCacheManager	(	RooAbsArg *	owner = `0`,
		Int_t	maxSize = `2`,
		Bool_t	clearCacheOnServerRedirect = `kTRUE`,
		Bool_t	allowOptimize = `kFALSE`
	)

Constructor of object cache manager for given owner.

If clearCacheOnServerRedirect is true all cache elements will be cleared when a server redirect is intercepted by the cache manager. This is the default strategy and should only be overridden when you really understand what you're doing as properly implementing server redirect in cache elements can get very complicated, especially if there are (cyclical) reference back to the owning object
