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.
  #include <json.hpp>
  using namespace nlohmann;
  int main()
  {
  // an anonymous enum
  enum { t = 17 };
  // create a JSON number from the enum
  json j(t);
  // serialize the JSON numbers
  std::cout << j << '\n';
  }

  Definition: json.hpp:130
  nlohmann
  namespace for Niels Lohmann
  Definition: json.hpp:55
  Output (play with this example online):

      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
