nlohmann::basic_json::basic_json ( const object_t &  value )

inline

Create an object JSON value with a given content.

Parameters

value

a value for the object

Complexity

Linear in the size of the passed value.

Exceptions

std::bad_alloc

if allocation for object value fails (thrown by the constructor of json_value)

Example

The following code shows the constructor with an object_t parameter.

#include <json.hpp>

using namespace nlohmann;

int main()
{
    // create an object_t value
    json::object_t value = { {"one", 1}, {"two", 2} };

    // create a JSON object from the value
    json j(value);

    // serialize the JSON object
    std::cout << j << '\n';
}

Output:

{"one":1,"two":2}

The example code above can be translated with

g++ -std=c++11 -Isrc doc/examples/basic_json__object_t.cpp -o basic_json__object_t 

.
