Detailed Description

template<class IteratorCategory, class Reference, class DifferenceType = std::ptrdiff_t>
struct Dune::DefaultIteratorTraits< IteratorCategory, Reference, DifferenceType >

An iterator_traits class providing sensible defaults.

Template Parameters

IteratorCategory	Category of the iterator, e.g. std::forward_iterator_tag
Reference	Reference type returns when dereferencing the iterator

This provides default types for value_type, pointer, and difference_type that should work for most iterator implementations including proxy iterators where the proxy types implement the Dune::AutonomousValue mechanism. The value_type is derived as Dune::AutonomousValue<reference>. The pointer type is a plain value_type* pointer if the reference is an l-value reference. Otherwise Dune::ProxyArrowResult<reference> is used to provide a suitable return type for operator-> for proxies.
