  4. def apply(child: Expression, extraction: Expression, resolver: Resolver): Expression

    Returns the resolved ExtractValue using the extractValue method call.

    Returns the resolved ExtractValue using the extractValue method call. In case the method returns None, it throws.

  9. def extractValue(child: Expression, extraction: Expression, resolver: Resolver): Either[Expression, Throwable]

    Returns the resolved ExtractValue.

    Returns the resolved ExtractValue. It will return one kind of concrete ExtractValue, depend on the type of child and extraction.

  12. def isExtractable(attribute: Attribute, nestedFields: Seq[String], extractorKey: Option[Expression] = None, resolver: Resolver): Boolean

    Check that attribute can be fully extracted using the given nestedFields and extractorKey.

    Check that attribute can be fully extracted using the given nestedFields and extractorKey. This method first tries to extract the innermost nested field using nestedFields. If such nested field is found, try to extract the value using extractorKey, if it exists. This method returns true if all attempted extractions are successful.
