Detailed Description

template<typename Iter>
struct theplu::yat::utility::iterator_traits< Iter >

The purpose of this class is to allow polymorphism between weighted and unweighted iterators. It allows to access data and weight for both weighted and unweighted iterators.

For weighted iterators this class requires that *Iter has functions data(void) and weight(void).

Member Typedef Documentation

template<typename Iter>

typedef traits::data_reference theplu::yat::utility::iterator_traits< Iter >::data_reference

For unweighted iterator, data_reference is the same as std::iterator_traits<Iter>::reference, i.e., the data if the iterator is the same as *Iter.

For weighted iterators, data_reference is double& if *Iter has a function double& data(void). Otherwise data_reference is const double.

template<typename Iter>

typedef traits::weight_reference theplu::yat::utility::iterator_traits< Iter >::weight_reference

For unweighted iterator, data_reference const double since the weight is always implicitly 1.0 and not mutable.

For weighted iterators, data_reference is double& if *Iter has a function double& data(void). Otherwise data_reference is const double.
