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

inlinenoexcept

Create an integer number JSON value with a given content. This constructor allows any type that can be used to construct values of type number_integer_t. Examples may include the types `int`, `int32_t`, or `short`.

Template Parameters

  CompatibleNumberIntegerType | an integer type which is compatible to number_integer_t.

Parameters

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

Complexity
  Constant.

Example
  The example below shows the construction of several JSON integer number values from compatible types.
  #include <json.hpp>
  using namespace nlohmann;
  int main()
  {
  // create values of different integer types
  short n42 = 42;
  int n23 = 23;
  long n1024 = 1024;
  int_least32_t n17 = 17;
  uint8_t n8 = 8;
  // create JSON numbers
  json j42(n42);
  json j23(n23);
  json j1024(n1024);
  json j17(n17);
  json j8(n8);
  // serialize the JSON numbers
  std::cout << j42 << '\n';
  std::cout << j23 << '\n';
  std::cout << j1024 << '\n';
  std::cout << j17 << '\n';
  std::cout << j8 << '\n';
  }

  Output (play with this example online):

      42
      23
      1024
      17
      8

  The example code above can be translated with

      g++ -std=c++11 -Isrc doc/examples/basic_json__CompatibleIntegerNumberType.cpp -o basic_json__CompatibleIntegerNumberType
