Detailed Description

template<typename BasicJsonType>
class 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)

constructor for a given JSON instance

Parameters

[in] object pointer to a JSON object for this iterator

Precondition: object != nullptr

Postcondition: The iterator is initialized; i.e. m_object != nullptr.

Definition at line 12968 of file json.hpp.

◆ iter_impl() [4/5]

template<typename BasicJsonType>

detail::iter_impl< BasicJsonType >::iter_impl ( const iter_impl< const BasicJsonType > & other )

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] other const 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
