class indexed_accessor_range_base

Declaration

template <typename DerivedT,
          typename BaseT,
          typename T,
          typename PointerT = T*,
          typename ReferenceT = T&>
class indexed_accessor_range_base { /* full declaration omitted */ };

Description

The class represents the base of a range of indexed_accessor_iterators. It provides support for many different range functionalities, e.g. drop_front/slice/etc.. Derived range classes must implement the following static methods: * ReferenceT dereference_iterator(const BaseT &base , ptrdiff_t index) - Dereference an iterator pointing to the base object at the given index. * BaseT offset_base(const BaseT &base , ptrdiff_t index) - Return a new base that is offset from the provide base by 'index' elements.
