Element Detail

value

public abstract String value

A date/time format string. If this annotation is applied to old-style dates and times, then this must be a string understood by SimpleDateFormat.SimpleDateFormat(java.lang.String). If it is applied to TemporalAccessor-based dates and times, then this must be a string understood by DateTimeFormatter. The default value works for both styles and conforms with ISO 8601. Locale information, if specified, is gleaned from one of the other CSV-related annotations and is used for conversion.

Returns:

The format string for parsing input

Default:

"yyyyMMdd\'T\'HHmmss"

writeFormatEqualsReadFormat

public abstract boolean writeFormatEqualsReadFormat

Whether or not the same format string is used for writing as for reading. If this is true, value() is used for both reading and writing and writeFormat() is ignored.

Returns:

Whether the read format is used for writing as well

Since:

5.0

Default:

true

writeFormat

public abstract String writeFormat

A date/time format string.

Returns:

The format string for formatting output

Since:

5.0

See Also:

value(), writeFormatEqualsReadFormat()

Default:

"yyyyMMdd\'T\'HHmmss"

chronology

public abstract String chronology

The Chronology that should be used for parsing.

The value must be understood by Chronology.of(String). The requisite ID for the desired Chronology can usually be found in the Javadoc for the getId() method of the specific implementation.

This value is only used for TemporalAccessor-based fields. It is ignored for old-style dates and times.

The default value specifies the ISO-8601 chronology. If a blank string or empty string is specified, the chronology is taken from the locale.

Returns:

The Chronology in use

Since:

5.0

Default:

"ISO"

writeChronologyEqualsReadChronology

public abstract boolean writeChronologyEqualsReadChronology

Whether or not the same chronology string is used for writing as for reading. If this is true, chronology() is used for both reading and writing and writeChronology() is ignored.

Returns:

Whether the read chronology is used for writing as well

Since:

5.0

Default:

true

writeChronology

public abstract String writeChronology

The Chronology that should be used for formatting.

Returns:

The Chronology in use

Since:

5.0

See Also:

chronology(), writeChronologyEqualsReadChronology()

Default:

"ISO"
