Defined in header <fkYAML/node.hpp>

fkyaml::operator<<

inline std::ostream& operator<<(std::ostream& os, const basic_node& n);

Extraction operator for basic_node template class.
Serializes YAML node values into an output stream.
This API is a wrapper of basic_node::serialize() function to simplify the implementation in the client code.
For more detailed descriptions, please visit the reference page for the basic_node::serialize() function.

Template Parameters

SequenceType

Type for sequence node value containers.

MappingType

Type for mapping node value containers.

BooleanType

Type for boolean node values.

IntegerType

Type for integer node values.

FloatNumberType

Type for float number node values.

StringType

Type for string node values.

ConverterType

Type for converters between nodes and values of native data types.

Parameters

os [in]

An output stream object.

n [in]

A basic_node object.

Return Value

Reference to the output stream object os.

Example

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

int main() {
    // create a basic_node object.
    fkyaml::node n = {{"foo", true}, {"bar", {1, 2, 3}}, {"baz", {{"qux", 3.14}, {"corge", nullptr}}}};

    // serialize the basic_node object with insertion operator.
    // this is equivalent with:
    //   std::cout << fkyaml::node::serialize(n) << std::endl;
    std::cout << n << std::endl;

    return 0;
}

output:

bar:
  - 1
  - 2
  - 3
baz:
  corge: null
  qux: 3.14
foo: true
