fkyaml::basic_node::get_tag_name

const std::string& get_tag_name() const;

Gets the tag name associated to the YAML node.
Some tag name must be set before calling this API.
Calling has_tag_name to see if the node has any tag name beforehand.

Return Value

The tag name associated to the node.
If no tag name has been set, an fkyaml::exception will be thrown.

Example

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

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

    // try to get a tag name before any tag name has been set.
    try {
        std::cout << n.get_tag_name() << std::endl;
    }
    catch (const fkyaml::exception& e) {
        std::cout << e.what() << std::endl;
    }

    // set a tag name to the node.
    n.add_tag_name("!!int");
    std::cout << n.get_tag_name() << std::endl;

    return 0;
}

output:

No tag name has been set.
!!int
