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. 1 #include <json.hpp> 2 3 using namespace nlohmann; 4 5 int main() 6 { 7 // create a JSON number from number_integer_t 8 json::number_integer_t value = 42; 9 10 json j(value); 11 12 // serialize the JSON numbers 13 std::cout << j << '\n'; 14 } nlohmann::basic_json a class to store JSON values Definition: json.hpp:187 nlohmann namespace for Niels Lohmann Definition: json.hpp:78 nlohmann::basic_json::number_integer_t NumberIntegerType number_integer_t a type for a number (integer) Definition: json.hpp:527 Output (play with this example online):
      42
  The example code above can be translated with
      g++ -std=c++11 -Isrc doc/examples/basic_json__number_integer_t.cpp -o basic_json__number_integer_t
