All Implemented Interfaces:

CsvParserCreator

public class DateTimeFormatterPatternParserCreator
extends Object
implements CsvParserCreator

Implementation of CsvParserCreator to create an instance DateTimeFormatterParser. This creator class is expected to be referenced from a Deephaven Schema for an Instant column. The following attributes are defined within the schema's ImportSource column definitions.

• If supplied, TIME_ZONE_ATTRIBUTE is used to specify the time zone used to parse data, otherwise the format pattern must include a way to determine the time zone from the data.
• FORMATTER_ATTRIBUTE provides the DateTimeFormatterBuilder.appendPattern(String) pattern for parsing data.
