nlohmann::basic_json::basic_json | ( | const CompatibleNumberIntegerType | value | ) |
| inline noexcept
  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. 1 #include <json.hpp> 2 3 using namespace nlohmann; 4 5 int main() 6 { 7 // create values of different integer types 8 short n42 = 42; 9 int n23 = 23; 10 long n1024 = 1024; 11 int_least32_t n17 = 17; 12 uint8_t n8 = 8; 13 14 // create JSON numbers 15 json j42(n42); 16 json j23(n23); 17 json j1024(n1024); 18 json j17(n17); 19 json j8(n8); 20 21 // serialize the JSON numbers 22 std::cout << j42 << '\n'; 23 std::cout << j23 << '\n'; 24 std::cout << j1024 << '\n'; 25 std::cout << j17 << '\n'; 26 std::cout << j8 << '\n'; 27 } nlohmann::basic_json a class to store JSON values Definition: json.hpp:187 nlohmann namespace for Niels Lohmann Definition: json.hpp:78 Output (play with this example online):
      42

  The example code above can be translated with
      g++ -std=c++11 -Isrc doc/examples/basic_json__CompatibleIntegerNumberType.cpp -o basic_json__CompatibleIntegerNumberType
