Class NullFieldParser

All Implemented Interfaces:

public class NullFieldParser extends NullValueParser
Parser for a field that contains only nulls. Waits, consuming nulls, until a non-null value appears, after which this parser is replaced by the "resolved" parser. The loader will force resolution at the end of the batch if no actual values are seen before then.
