Defined in header <fkYAML/node.hpp>

fkyaml::basic_node::operator==

bool operator==(const basic_node& rhs) const noexcept;

Equal-to operator.
Compares two basic_node objects for equality according to the following rules:

• Two basic_node objects are equal if they are of the same node_t type and their stored values are the same according to their respective operator==.
• Two basic_node objects are always equal if both of them are of the node_t::NULL_OBJECT type.

Parameters

rhs [in]

A basic_node object to be compared with this object.

Return Value

true if both types and values are equal, false otherwise.

Example

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

int main() {
    // create YAML nodes.
    fkyaml::node seq_1 = {1, 2, 3};
    fkyaml::node seq_2 = {1, 2, 4};
    fkyaml::node map_1 = {{"foo", true}, {"bar", 123}};
    fkyaml::node map_2 = {{"bar", 123}, {"foo", true}};
    fkyaml::node null_1 = nullptr;
    fkyaml::node null_2 = nullptr;
    fkyaml::node bool_1 = true;
    fkyaml::node bool_2 = false;
    fkyaml::node integer_1 = 123;
    fkyaml::node integer_2 = 123;
    fkyaml::node float_1 = 3.14;
    fkyaml::node float_2 = 3.14;
    fkyaml::node string_1 = "foo";
    fkyaml::node string_2 = "bar";

    // the same type
    std::cout << std::boolalpha;
    std::cout << (seq_1 == seq_2) << std::endl;
    std::cout << (map_1 == map_2) << std::endl;
    std::cout << (null_1 == null_2) << std::endl;
    std::cout << (bool_1 == bool_2) << std::endl;
    std::cout << (integer_1 == integer_2) << std::endl;
    std::cout << (float_1 == float_2) << std::endl;
    std::cout << (string_1 == string_2) << std::endl;

    // different types
    std::cout << (bool_1 == string_1) << std::endl;
    std::cout << (float_2 == seq_2) << std::endl;

    return 0;
}

output:

false
true
true
false
true
true
false
false
false
