Detailed Description

template<class Iterator>
struct theplu::yat::utility::weighted_iterator_traits< Iterator >

Metafunction to decide whether an Iterator is weighted or non-weighted. This (default) implementation returns unweighted_iterator_tag, unless value_type of Iterator is convertible to DataWeight in which case weighted_iterator_tag is returned.

Type Requirements:

• boost::iterator_value<Iterator>::type must be defined, which is guaranteed if Iterator is a Readable Iterator (std::ostream_iterator e.g. does not work)

template<class Iterator>

typedef detail::weighted_iterator_traits_detail<value>::type theplu::yat::utility::weighted_iterator_traits< Iterator >::type

Returns

weighted_iterator_tag if Iterator::value_type is convertible to DataWeight
