Defined in header <fkYAML/node.hpp>

fkyaml::basic_node::as_int

integer_type& as_int();
const integer_type& as_int() const;

Returns (const) reference to the integer node value.
If the current node value is not an integer, a fkyaml::type_error will be thrown.

Return Value

(const) reference to the integer node value.

Examples

Example

#include <iostream>
#include <fkYAML/node.hpp>

int main() {
    // create a integer node.
    fkyaml::node n = 123;

    // get reference to the integer value from a non-const node.
    // use `auto&` or `fkyaml::node::integer_type&` for forward compatibility.
    auto& i = n.as_int();
    // get const reference to the integer value from a const node.
    const fkyaml::node cn = n;
    const auto& ci = cn.as_int();

    // modify the integer value.
    i = 321;

    std::cout << i << std::endl;
    std::cout << ci << std::endl;
}

output:

321
123
