class nlohmann::basic_json< ObjectType, ArrayType, StringType, BooleanType, NumberIntegerType, NumberUnsignedType, NumberFloatType, AllocatorType >::iterator

a mutable random access iterator for the basic_json class

@requirement The class satisfies the following concept requirements:

• RandomAccessIterator: The iterator that can be moved to point (forward and backward) to any element in constant time.
• OutputIterator: It is possible to write to the pointed-to element.
