class RooNormSetCache

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.

Function documentation

RooNormSetCache(Int_t regSize = 64)

 Construct normalization set manager with given initial size
_htable = regSize>16 ? new RooHashTable(regSize,RooHashTable::Intrinsic) : 0 ;

RooNormSetCache(const RooNormSetCache& other)

 Copy constructor

~RooNormSetCache()

 Destructor

void clear()

 Clear contents

void initialize(const RooNormSetCache& other)

 Initialize cache from contents of given other cache

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

 Add given pair of RooArgSet pointers to our store

void expand()

 Expand registry size by doubling capacity

Bool_t autoCache(const RooAbsArg* self, const RooArgSet* set1, const RooArgSet* set2 = 0, const TNamed* set2RangeName = 0, Bool_t autoRefill = 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.
