Detailed Description

YAML implementation of the IParser interface.

YAMLParser can:

• parse a YAML-like string into a DBNode hierarchy,
• write a DBNode hierarchy to a YAML file,
• read a DBNode hierarchy back from a YAML file.

The parser is intentionally minimal and focuses on the subset of YAML needed by the project (indentation-based maps and lists).

Member Function Documentation

parse()

std::shared_ptr< DBNode > YAMLParser::parse ( const std::string &  input ) const

overridevirtual

Parses a YAML string into a DBNode hierarchy.

Parameters

input

YAML text buffer.

Returns

Shared pointer to the root DBNode of the parsed document.

Exceptions

std::runtime_error

on syntax or conversion errors.

Implements IParser.

Definition at line 21 of file YamlParser.cpp.

readFromFile()

std::shared_ptr< DBNode > YAMLParser::readFromFile ( const std::string &  filename ) const

overridevirtual

Reads and parses YAML data from a file.

The file contents are loaded into memory and passed to parse().

Parameters

filename

Source file name.

Returns

Shared pointer to the root DBNode of the parsed document.

Exceptions

std::runtime_error

if the file cannot be opened or parsing fails.

Implements IParser.

Definition at line 209 of file YamlParser.cpp.

writeToFile()

void YAMLParser::writeToFile ( const std::string &  filename, const std::shared_ptr< DBNode > &  root  ) const

overridevirtual

Writes a DBNode hierarchy to a YAML file.

This uses DBNode::printYAMLToStream() to serialize the tree in a readable YAML-like format.

Parameters

filename	Target file name.
root	Root node to serialize.

Exceptions

std::runtime_error

if the file cannot be opened or writing fails.

Implements IParser.
