Defined in header <fkYAML/node.hpp>

fkyaml::operator<<

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

Serializes a node value into an output stream.
This operator is a wrapper of the basic_node::serialize() function to simplify the implementation in the client code.
For details, please visit the documentation of the 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.

Examples

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
