Detailed Description

template<template< typename U, typename V, typename...Args > class ObjectType = std::map, template< typename U, typename...Args > class ArrayType = std::vector, class StringType = std::string, class BooleanType = bool, class NumberIntegerType = std::int64_t, class NumberUnsignedType = std::uint64_t, class NumberFloatType = double, template< typename U > class AllocatorType = std::allocator>
class nlohmann::basic_json< ObjectType, ArrayType, StringType, BooleanType, NumberIntegerType, NumberUnsignedType, NumberFloatType, AllocatorType >::iterator

a mutable random access iterator for the basic_json class

The class satisfies the following concept requirements:

• [RandomAccessIterator](http://en.cppreference.com/w/cpp/concept/RandomAccessIterator): The iterator that can be moved to point (forward and backward) to any element in constant time.
• [OutputIterator](http://en.cppreference.com/w/cpp/concept/OutputIterator): It is possible to write to the pointed-to element.

Since:

version 1.0.0
