18. def parseAttributeName(name: String): Seq[String]

    Used to split attribute name by dot with backticks rule.

    Used to split attribute name by dot with backticks rule. Backticks must appear in pairs, and the quoted string must be a complete name part, which means ab..ce.f is not allowed. Escape character is not supported now, so we can't use backtick inside name part.

19. def quoted(name: String): UnresolvedAttribute

    Creates an UnresolvedAttribute, from a single quoted string (for example using backticks in HiveQL.

    Creates an UnresolvedAttribute, from a single quoted string (for example using backticks in HiveQL. Since the string is consider quoted, no processing is done on the name.

20. def quotedString(name: String): UnresolvedAttribute

    Creates an UnresolvedAttribute from a string in an embedded language.

    Creates an UnresolvedAttribute from a string in an embedded language. In this case we treat it as a quoted identifier, except for '.', which must be further quoted using backticks if it is part of a column name.
