yyjson_obj_iter Struct Reference

#include <yyjson.h>

Data Fields
size_t	idx
size_t	max
yyjson_val *	cur
yyjson_val *	obj

Detailed Description

A JSON object iterator.

Example

yyjson_val *key, *val;
yyjson_obj_iter iter = yyjson_obj_iter_with(obj);
while ((key = yyjson_obj_iter_next(&iter))) {
    val = yyjson_obj_iter_get_val(key);
    your_func(key, val);
}

If the ordering of the keys is known at compile-time, you can use this method to speed up value lookups:

// {"k1":1, "k2": 3, "k3": 3}
yyjson_val *key, *val;
yyjson_obj_iter iter = yyjson_obj_iter_with(obj);
yyjson_val *v1 = yyjson_obj_iter_get(&iter, "k1");
yyjson_val *v3 = yyjson_obj_iter_get(&iter, "k3");
