nlohmann::basic_json::basic_json | ( | const number_integer_t | value | ) |

inline

Create an interger number JSON value with a given content.

Template Parameters

  T | helper type to compare number_integer_t and int (not visible in) the interface.

Parameters

  [in] | value | an integer to create a JSON number from

Note
  This constructor would have the same signature as basic_json(const int value), so we need to switch this one off in case number_integer_t is the same as int. This is done via the helper type T.

Complexity
  Constant.

Example
  The example below shows the construction of a JSON integer number value.
  #include <json.hpp>
  using namespace nlohmann;
  int main()
  {
  // create a JSON number from number_integer_t
  json::number_integer_t value = 42;
  json j(value);
  // serialize the JSON numbers
  std::cout << j << '\n';
  }

  nlohmann
  namespace for Niels Lohmann

  nlohmann::basic_json::number_integer_t
  NumberIntegerType number_integer_t
  a type for a number (integer)
  Definition: json.hpp:435
  Output (play with this example online):

      42
