nlohmann::basic_json::basic_json ( const number_integer_t  value )

inline

Create an interger number JSON value with a given content.

Template Parameters

T	helper type to compare number_integer_t and int (not visible in) the interface.

Parameters

[in]

value

an integer to create a JSON number from

Note

This constructor would have the same signature as basic_json(const int value), so we need to switch this one off in case number_integer_t is the same as int. This is done via the helper type T.

Complexity

Constant.

Example

The example below shows the construction of a JSON integer number value.

#include <json.hpp>

using namespace nlohmann;

int main()
{
    // create a JSON number from number_integer_t
    json::number_integer_t value = 42;

    json j(value);

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

Output:

42

The example code above can be translated with

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

.
