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\n Linear in the size of init.
- Example\n The following code shows an example for the
object - function.
static basic_json array(std::initializer_list< basic_json > init=std::initializer_list< basic_json >()) explicitly create an array from an initializer list
static basic_json object(std::initializer_list< basic_json > init=std::initializer_list< basic_json >()) explicitly create an object from an initializer list
a class to store JSON values
basic_json<> json default JSON class
Output (play with this example online):
{}
{}
{"one":1,"two":2}
The example code above can be translated with g++ -std=c++11 -Isrc doc/examples/object.cpp -o object
