  Compares whether one JSON value lhs is less than another JSON value rhs according to the following rules: If lhs and rhs have the same type, the values are compared using the default `<` operator. Integer and floating-point numbers are automatically converted before comparison In case lhs and rhs have different types, the values are ignored and the order of the types is considered, see operator<(const value_t, const value_t). Parameters
  [in] | lhs | first JSON value to consider
  [in] | rhs | second JSON value to consider
  Returns whether lhs is less than rhs Complexity Linear. Example The example demonstrates comparing several JSON types. 1 #include <json.hpp> 2 3 using namespace nlohmann; 4 5 int main() 6 { 7 // create several JSON values 8 json array_1 = {1, 2, 3}; 9 json array_2 = {1, 2, 4}; 10 json object_1 = {{"A", "a"}, {"B", "b"}}; 11 json object_2 = {{"B", "b"}, {"A", "a"}}; 12 json number_1 = 17; 13 json number_2 = 17.0000000000001L; 14 json string_1 = "foo"; 15 json string_2 = "bar"; 16 17 // output values and comparisons 18 std::cout << std::boolalpha; 19 std::cout << array_1 << " == " << array_2 << " " << (array_1 < array_2) << '\n'; 20 std::cout << object_1 << " == " << object_2 << " " << (object_1 < object_2) << '\n'; 21 std::cout << number_1 << " == " << number_2 << " " << (number_1 < number_2) << '\n'; 22 std::cout << string_1 << " == " << string_2 << " " << (string_1 < string_2) << '\n'; 23 } nlohmann::basic_json a class to store JSON values Definition: json.hpp:191 nlohmann namespace for Niels Lohmann Definition: json.hpp:88 Output (play with this example online):
      [1,2,3] == [1,2,4] true
      {"A":"a","B":"b"} == {"A":"a","B":"b"} false
      17 == 17.0000000000001 true
      "foo" == "bar" false
  The example code above can be translated with
      g++ -std=c++11 -Isrc doc/examples/operator__less.cpp -o operator__less
