Compares whether one JSON value lhs is greater than another JSON value by calculating not (lhs <= rhs) .
- Parameters
-
[in] | lhs | first JSON value to consider |
[in] | rhs | second JSON value to consider |
- Returns
- whether lhs is greater than to rhs
- Complexity^^ Linear.
- Exception safety^^ No-throw guarantee: this function never throws exceptions.
- Example^^ The example demonstrates comparing several JSON
- types. ^^
2 #include <nlohmann/json.hpp> 9 json array_1 = {1, 2, 3}; 10 json array_2 = {1, 2, 4}; 11 json object_1 = {{ "A", "a"}, { "B", "b"}}; 12 json object_2 = {{ "B", "b"}, { "A", "a"}}; 14 json number_2 = 17.0000000000001L; 15 json string_1 = "foo"; 16 json string_2 = "bar"; 19 std::cout << std::boolalpha; 20 std::cout << array_1 << " <= " << array_2 << " " << (array_1 <= array_2) << '\n'; 21 std::cout << object_1 << " <= " << object_2 << " " << (object_1 <= object_2) << '\n'; 22 std::cout << number_1 << " <= " << number_2 << " " << (number_1 <= number_2) << '\n'; 23 std::cout << string_1 << " <= " << string_2 << " " << (string_1 <= string_2) << '\n'; basic_json<> json default JSON class
Output (play with this example online):^^ [1,2,3] <= [1,2,4] true
{"A":"a","B":"b"} <= {"A":"a","B":"b"} true
17 <= 17.0000000000001 true
"foo" <= "bar" false
