public static ResolvedFieldReference[] getAccessedFields(TimestampExtractor timestampExtractor,
                                                         DataType physicalInputType,
                                                         Function<String,String> nameRemapping)

Retrieves all field accesses needed for the given TimestampExtractor.

Parameters:

timestampExtractor - Extractor for which to construct array of field accesses.

physicalInputType - Physical input type that the timestamp extractor accesses.

nameRemapping - Additional remapping of a logical to a physical field name. TimestampExtractor works with logical names, but accesses physical fields

Returns:

Array of physical field references.
