示例1: getSortedResults
void getSortedResults(IteratorPtr<LookupResult<T> > pFindResultIter,
DistanceCalculatorPtr<T> pDistanceCaculator,
T pTarget,
ElementWithDistances<T>& sortedResults) {
pFindResultIter->toBegin();
//Traverse iterator to get element and push to results vector
while(!pFindResultIter->isDone()) {
#ifdef DENOISING
if(pFindResultIter->getObj().m_distanceToTarget >= NOISE_THRESOLD) {
sortedResults.push_back(pFindResultIter->getObj());
}
#endif
pFindResultIter->next();
}
//Wind-back the iterator for future purpose
pFindResultIter->toBegin();
}示例2:
IteratorPtr<LookupResult<T> > ComposerBasedElementApproximator<T>::getFullResultIterator(IteratorPtr<LookupResult<T> > pResultIter,

}

//Filter results before sort
if(m_pLookupResultFilter != NullPtr) {

}

}
