示例1: Sort
// Sort elements and return sort index mapping.
bool NgramVector::Sort(const VocabVector &vocabMap,
const IndexVector &boNgramMap,
IndexVector &ngramMap) {
// Update word and hist indices.
for (size_t i = 0; i < size(); ++i) {
_words[i] = vocabMap[_words[i]];
_hists[i] = boNgramMap[_hists[i]];
}
// Sort indices.
NgramIndexCompare compare(*this);
IndexVector sortIndices = Range(0, size());
if (!sortIndices.sort(compare)) {
ngramMap = Range(size());
return false;
}
// Apply ordered indices to values.
// Build sort mapping that maps old to new indices.
VocabVector newWords(_words.length());
IndexVector newHists(_hists.length());
ngramMap.reset(size());
for (NgramIndex i = 0; i < (NgramIndex)size(); i++) {
newWords[i] = _words[sortIndices[i]];
newHists[i] = _hists[sortIndices[i]];
ngramMap[sortIndices[i]] = i;
}
_words.swap(newWords);
_hists.swap(newHists);
// Rebuild index map.
_Reindex(_indices.length());
// Build truncated view into words and hists.
Range r(_length);
_wordsView.attach(_words[r]);
_histsView.attach(_hists[r]);
return true;
