Examples

Example

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

int main() {
    // create a string node.
    fkyaml::node n = "foo";

    // get reference to the string value from a non-const node.
    // use `auto&` or `fkyaml::node::string_type&` for forward compatibility.
    auto& s = n.as_str();
    // get const reference to the string value from a const node.
    const fkyaml::node cn = n;
    const auto& cs = cn.as_str();

    // modify the string value.
    s = "bar";

    std::cout << s << std::endl;
    std::cout << cs << std::endl;
}

output:

bar
foo
