nlohmann::basic_json::basic_json ( boolean_t  value )

inline

Creates a JSON boolean type from a given value.

Parameters

[in]

value

a boolean value to store

Complexity

Constant.

Example

The example below demonstrates boolean values.

#include <json.hpp>

using namespace nlohmann;

int main()
{
    // create boolean values
    json j_truth = true;
    json j_falsity = false;

    // serialize the JSON booleans
    std::cout << j_truth << '\n';
    std::cout << j_falsity << '\n';
}

Output:

true
false

The example code above can be translated with

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