Private Instance Methods
Parse the specified value as though it is a single-line value part of a YAML key/value pair.
Attempt to parse the specified String value as though it is a single-line value part of a YAML key/value pair. If the value fails to parse, wrap the value in single quotes (after escaping any single quotes in the value) and parse it as a character sequence. If the value is empty, return an empty String.
@param val [String] the value to parse.
@return [Object, String] the value parsed from the string-based YAML value or an empty String if the specified value is empty.
