| ## ◆ crend()
const_reverse_iterator nlohmann::basic_json::crend | ( |  | ) | const
| inlinenoexcept
  Returns a const reverse iterator to the reverse-end; that is, one before the first element. Illustration from cppreference.com Complexity Constant. Requirements This function helps `basic_json` satisfying the ReversibleContainer requirements: The complexity is constant. Has the semantics of `const_cast<const basic_json&>(*this).rend()`. Example The following code shows an example for `crend()`. 1 #include <iostream> 2 #include <nlohmann/json.hpp> 3 4 using json = nlohmann::json; 5 6 int main() 7 { 8 // create an array value 9 json array = {1, 2, 3, 4, 5}; 10 11 // get an iterator to the reverse-end 12 json::const_reverse_iterator it = array.crend(); 13 14 // increment the iterator to point to the first element 15 --it; 16 17 // serialize the element that the iterator points to 18 std::cout << *it << '\n'; 19 } Output (play with this example online):
      1
  The example code above can be translated with
      g++ -std=c++11 -Isingle_include doc/examples/crend.cpp -o crend
See also rend() – returns a reverse iterator to the end rbegin() – returns a reverse iterator to the beginning crbegin() – returns a const reverse iterator to the beginning Since version 1.0.0 Definition at line 20505 of file json.hpp.
