const_iterator nlohmann::basic_json::end ( ) const
inlinenoexcept

Returns a const iterator to one past the last element.

Illustration from cppreference.com
Returns
const iterator one past the last element
Complexity
Constant.
Requirements
This function helps basic_json satisfying the Container requirements:
  • The complexity is constant.
  • Has the semantics of const_cast<const basic_json&>(*this).end().
Example
The following code shows an example for cend().
1 #include <json.hpp>
2 
3 using json = nlohmann::json;
4 
5 int main()
6 {
7  // create an array value
8  json array = {1, 2, 3, 4, 5};
9 
10  // get am iterator to one past the last element
11  json::const_iterator it = array.cend();
12 
13  // decrement the iterator to point to the last element
14  --it;
15 
16  // serialize the element that the iterator points to
17  std::cout << *it << '\n';
18 }
