Defined in header <fkYAML/node.hpp>

fkyaml::basic_node::operator!=

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

Not-Equal-to operator.
Compares two basic_node objects for inequality.
This operator returns the result of !(*this == rhs). (see operator==)

Parameters

rhs [in]

A basic_node object to be compared with this object.

Return Value

true if either types or values are not 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:

true
false
false
true
false
false
true
true
true
