示例1: stitch
void Path::stitch(Sequence::iterator first_replaced,
Sequence::iterator last_replaced,
Sequence &source)
{
if (!source.empty()) {
if ( first_replaced != get_curves().begin() ) {
if ( (*first_replaced)->initialPoint() != source.front()->initialPoint() ) {
Curve *stitch = new StitchSegment((*first_replaced)->initialPoint(),
source.front()->initialPoint());
source.insert(source.begin(), boost::shared_ptr<Curve>(stitch));
}
}

Curve *stitch = new StitchSegment(source.back()->finalPoint(),
(*last_replaced)->finalPoint());
source.insert(source.end(), boost::shared_ptr<Curve>(stitch));
}
}
} else if ( first_replaced != last_replaced && first_replaced != get_curves().begin() && last_replaced != get_curves().end()-1) {
if ( (*first_replaced)->initialPoint() != (*(last_replaced-1))->finalPoint() ) {

}示例2: getPercentile
double DeterminatorInterpolated::getPercentile(const Sequence &sequence, int percentile) const {
size_t size = sequence.size();
double coeff = 100.0 / size;
double calcIdx = percentile / coeff - .5;
if (calcIdx <= 0) return sequence.front();
if (calcIdx >= size - 1) return sequence.back();
size_t idx0 = (size_t) floor(calcIdx);
int v0 = sequence.at(idx0);
int v1 = sequence.at(idx0 + 1);
double p0 = 100.0 / size * (idx0);
double slope = size / 100.0 * (percentile - p0);
return v0 + (v1 - v0) * slope;
