Detailed Description

template<typename Base>
class nlohmann::detail::json_reverse_iterator< Base >

a template for a reverse iterator class

Template Parameters

Base	the base iterator type to reverse. Valid types are iterator (to create reverse_iterator) and const_iterator (to create const_reverse_iterator).

@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).
• OutputIterator: It is possible to write to the pointed-to element (only if Base is iterator).
