Creates a JSON object value from a given initializer list. The initializer lists elements must be pairs, and their first elements must be strings. If the initializer list is empty, the empty object {} is created.
- Note
- This function is only added for symmetry reasons. In contrast to the related function array(std::initializer_list<basic_json>), there are no cases which can only be expressed by this function. That is, any initializer list init can also be passed to the initializer list constructor basic_json(std::initializer_list<basic_json>, bool, value_t).
- Parameters
-
[in] | init | initializer list to create an object from (optional) |
- Returns
- JSON object value
- Exceptions
-
- Complexity
- Linear in the size of init.
- Example
- The following code shows an example for the
object function. 14 std::cout << j_no_init_list << '\n'; 15 std::cout << j_empty_init_list << '\n'; 16 std::cout << j_list_of_pairs << '\n'; static basic_json object(std::initializer_list< basic_json > init=std::initializer_list< basic_json >()) explicitly create an object from an initializer list
basic_json<> json default JSON class
Output (play with this example online): {}
{}
{"one":1,"two":2}
The example code above can be translated withg++ -std=c++11 -Isrc doc/examples/object.cpp -o object
