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.
- 注解
- 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).
- 自从
- 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)
