Detailed Description
template<typename DataIterator, typename WeightIterator>
class theplu::yat::utility::WeightedIterator< DataIterator, WeightIterator >
Adaptor enabling to make two unweighted iterators to behave like a Weighted Iterator. The data part corresponds to the data_iterator and the weight corresponds to the weight_iterator.
WeightedIterator is a Weighted Iterator and its value_type is DataWeight. However due to the nature of this adaptor there are no physical DataWeight in memory that WeightedIterator points to, so its reference_type is not DataWeight& but a DataWeightProxy. As a proxy is used, which is not allowed in a Forward Iterator, WeightedIterator is a Input Iterator.
Although WeightedIterator is tagged a Input Iterator, more advanced traversal is implemented if supported by underlying iterators. If underlying iterators support random access traversal, e.g., WeightedIterator supports it as well and boost::iterator_traversal<T>::type is set appropriately (see Random Access Traversal Iterator).
Type Requirements:
DataWeightProxy<DataIterator, WeightIterator>is a valid expression.

Default Constructor.
Created iterator is not dereferencable
- Since
- New in yat 0.6

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.
