RooNormSetCache Class Reference

Class RooNormSet cache manage the bookkeeping of multiple instances of sets of integration and normalization observables that effectively have the same definition.

In complex function expression many RooArgSets with the same contents may be passed to an object that caches intermediate results dependent on the normalization/integration set To avoid unnecessary cache faulting, This class tracks all instances with the same contents and reports to the owner if the present nset/iset is truely different from the current reference. Class RooNormSet only evaluates each RooArgSet pointer once, it therefore assumes that RooArgSets with normalization and/or integration sets are not changes during their lifetime.

add()

void RooNormSetCache::add	(	const RooArgSet *	set1,
		const RooArgSet *	set2 = 0
	)

Add given pair of RooArgSet pointers to our store.

autoCache()

Bool_t RooNormSetCache::autoCache	(	const RooAbsArg *	self,
		const RooArgSet *	set1,
		const RooArgSet *	set2 = 0,
		const TNamed *	set2RangeName = 0,
		Bool_t	doRefill = kTRUE
	)

If RooArgSets set1 and set2 or sets with similar contents have been seen by this cache manager before return kFALSE If not, return kTRUE.

If sets have not been seen and doRefill is true, update cache reference to current input sets.
