Detailed Description

template<typename Base>
class theplu::yat::utility::WeightIterator< Base >

WeightIterator.

WeightIterator is an iterator adaptor that enables iterating over a weighted range but accessing only the weight part of the range. The iterator behaves just like it Base iterator except that operator* returns iterator_traits<Base>.weight(base), i.e., the weight part is returned.

Here is a short example illustrating typical usage:

std::vector<DataWeight> weighted_vec;
...
std::vector<double> vec(weighted_vec.size());
std::copy(weight_iterator(weighted_vec.begin()),
          weight_iterator(weighted_vec.end()),
          vec.begin());

Type Requirement:

• BASE must model a Data Iterator

Constructor & Destructor Documentation

template<typename Base>

theplu::yat::utility::WeightIterator< Base >::WeightIterator ( void  )

inline

Default Constructor.

Since

New in yat 0.6

template<typename Base>

template<typename B2 >

theplu::yat::utility::WeightIterator< Base >::WeightIterator ( WeightIterator< B2 >  other, typename boost::enable_if_convertible< B2, Base >::type *  = 0  )

inline

Conversion constructor.

Create a WeightIterator<Base> from a WeightIterator<B2>. Possible if B2 is convertible to a Base. Constructor allows implicit conversions such as iterator to const_iterator.
