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

inline

Create a string JSON value with a given content.

Parameters

[in]

value

a value for the string

Template Parameters

CompatibleStringType

an string type which is compatible to string_t

Complexity

Linear in the size of the passed value.

Exceptions

std::bad_alloc

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

Example

The following code shows the construction of a string value from a compatible type.

#include <json.hpp>

using namespace nlohmann;

int main()
{
    // create a string value
    std::string s = "The quick brown fox jumps over the lazy dog.";

    // create a JSON string value
    json j = s;

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

Output:

"The quick brown fox jumps over the lazy dog."

The example code above can be translated with

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

.
