const_reverse_iterator nlohmann::basic_json::rbegin | ( |  | ) | const
| inline noexcept
  Returns a const iterator to the reverse-beginning; that is, the last element. Illustration from cppreference.com Complexity Constant. Requirements This function satisfies the ReversibleContainer requirements: The complexity is constant. Has the semantics of `const_cast<const basic_json&>(*this).rbegin()`. Example The following code shows an example for crbegin. 1 #include <json.hpp> 2 3 using namespace nlohmann; 4 5 int main() 6 { 7 // create an array value 8 json array = {1, 2, 3, 4, 5}; 9 10 // get an iterator to the reverse-beginning 11 json::const_reverse_iterator it = array.crbegin(); 12 13 // serialize the element that the iterator points to 14 std::cout << *it << '\n'; 15 } nlohmann::basic_json a class to store JSON values Definition: json.hpp:121 nlohmann::basic_json::const_reverse_iterator a const reverse random access iterator for the basic_json class Definition: json.hpp:5014 nlohmann namespace for Niels Lohmann Definition: json.hpp:56 nlohmann::basic_json::crbegin const_reverse_iterator crbegin() const noexcept returns a const reverse iterator to the last element Definition: json.hpp:2840 Output:
      5
