#include <CGAL/Multiscale_sort.h>

Definition

The class Multiscale_sort represents a sorting algorithm adaptor.

Given a range of n points:

  1. it applies Sort on the last (1 - ratio) * n points,
  2. it recurses on the first ratio * n points, stopping when there are less than threshold points.

Creation

 Multiscale_sort (const Sort &sort=Sort(), std::ptrdiff_t threshold=1, double ratio=0.5)
 constructs an instance with traits as traits class instance. More...
 

Operations

template<class RandomAccessIterator >
void operator() (RandomAccessIterator begin, RandomAccessIterator end) const
 sorts the range [begin, end). More...
 

Constructor & Destructor Documentation

template<typename Sort >
CGAL::Multiscale_sort< Sort >::Multiscale_sort ( const Sort &  sort = Sort(),
std::ptrdiff_t  threshold = 1,
double  ratio = 0.5 
)

constructs an instance with traits as traits class instance.

Member Function Documentation

template<typename Sort >
template<class RandomAccessIterator >
void CGAL::Multiscale_sort< Sort >::operator() ( RandomAccessIterator  begin,
RandomAccessIterator  end 
) const

sorts the range [begin, end).

Requires:
Sort::operator()(RandomAccessIterator begin, RandomAccessIterator end) is defined.
