nlohmann::basic_json::basic_json ( const array_t val)
inline

Create an array JSON value with a given content.

Parameters
[in]vala value for the array
Complexity
Linear in the size of the passed val.
Exceptions
std::bad_allocif allocation for array value fails
Example
The following code shows the constructor with an array_t parameter.
1 #include <json.hpp>
2 
3 using json = nlohmann::json;
4 
5 int main()
6 {
7  // create an array_t value
8  json::array_t value = {"one", "two", 3, 4.5, false};
9 
10  // create a JSON array from the value
11  json j(value);
12 
13  // serialize the JSON array
14  std::cout << j << '\n';
15 }
basic_json<> json
