nlohmann::basic_json::basic_json | ( | const int | value | ) |
| inline
  Create an integer number JSON value with a given content. Parameters
  [in] | value | an integer to create a JSON number from
  Note This constructor allows to pass enums directly to a constructor. As C++ has no way of specifying the type of an anonymous enum explicitly, we can only rely on the fact that such values implicitly convert to int. As int may already be the same type of number_integer_t, we may need to switch off the constructor basic_json(const number_integer_t). Complexity Constant. Example The example below shows the construction of a JSON integer number value from an anonymous enum. 1 #include <json.hpp> 2 3 using namespace nlohmann; 4 5 int main() 6 { 7 // an anonymous enum 8 enum { t = 17 }; 9 10 // create a JSON number from the enum 11 json j(t); 12 13 // serialize the JSON numbers 14 std::cout << j << '\n'; 15 } nlohmann::basic_json a class to store JSON values Definition: json.hpp:121 nlohmann namespace for Niels Lohmann Definition: json.hpp:56 Output:
      17
  The example code above can be translated with
      g++ -std=c++11 -Isrc doc/examples/basic_json__const_int.cpp -o basic_json__const_int
