Detailed Description

template<typename BasicJsonType>
class nlohmann::detail::iter_impl< BasicJsonType >

a template for a bidirectional iterator for the basic_json class This class implements a both iterators (iterator and const_iterator) for the basic_json class.

Note
An iterator is called initialized when a pointer to a JSON value has been set (e.g., by a constructor or a copy assignment). If the iterator is default-constructed, it is uninitialized and most methods are undefined. The library uses assertions to detect calls on uninitialized iterators.** @requirement The class satisfies the following concept requirements:
  • BidirectionalIterator: The iterator that can be moved can be moved in both directions (i.e. incremented and decremented).
Since
version 1.0.0, simplified in version 2.0.9, change to bidirectional iterators in version 3.0.0 (see https://github.com/nlohmann/json/issues/593)

◆ array_t

private

Definition at line 11417 of file json.hpp.

◆ difference_type

template<typename BasicJsonType >
using nlohmann::detail::iter_impl< BasicJsonType >::difference_type = typename BasicJsonType::difference_type

Definition at line 11434 of file json.hpp.

◆ iterator_category

template<typename BasicJsonType >
using nlohmann::detail::iter_impl< BasicJsonType >::iterator_category = std::bidirectional_iterator_tag

The std::iterator class template (used as a base class to provide typedefs) is deprecated in C++17. The C++ Standard has never required user-defined iterators to derive from std::iterator. A user-defined iterator should provide publicly accessible typedefs named iterator_category, value_type, difference_type, pointer, and reference. Note that value_type is required to be non-const, even for constant iterators.

◆ iter_impl() [4/5]

template<typename BasicJsonType >

inlinenoexcept

const copy constructor

Note
The conventional copy constructor and copy assignment are implicitly defined. Combined with the following converting constructor and assignment, they support: (1) copy from iterator to iterator, (2) copy from const iterator to const iterator, and (3) conversion from iterator to const iterator. However conversion from const iterator to iterator is not defined.
Parameters
[in]otherconst iterator to copy from
Note
This copy constructor had to be defined explicitly to circumvent a bug occurring on msvc v19.0 compiler (VS 2015) debug build. For more information refer to: https://github.com/nlohmann/json/issues/1608
