    public LocalDateTimeStringConverter()

    Create a StringConverter for LocalDateTime values, using a default formatter and parser based on IsoChronology, FormatStyle.SHORT for both date and time, and the user's Locale.

    This converter ensures symmetry between the toString() and fromString() methods. Many of the default locale based patterns used by DateTimeFormatter will display only two digits for the year when formatting to a string. This would cause a value like 1955 to be displayed as 55, which in turn would be parsed back as 2055. This converter modifies two-digit year patterns to always use four digits. The input parsing is not affected, so two digit year values can still be parsed as expected in these locales.

    public LocalDateTimeStringConverter(FormatStyle dateStyle,
                                        FormatStyle timeStyle)

    Create a StringConverter for LocalDateTime values, using a default formatter and parser based on IsoChronology, the specified FormatStyle values for date and time, and the user's Locale.

    Parameters:

    dateStyle - The FormatStyle that will be used by the default formatter and parser for the date. If null then FormatStyle.SHORT will be used.

    public LocalDateTimeStringConverter(DateTimeFormatter formatter,
                                        DateTimeFormatter parser)

    Create a StringConverter for LocalDateTime values using the supplied formatter and parser.

    For example, to use a fixed pattern for converting both ways:

    String pattern = "yyyy-MM-dd HH:mm";
     DateTimeFormatter formatter = DateTimeFormatter.ofPattern(pattern);
     StringConverter converter =
         DateTimeStringConverter.getLocalDateTimeConverter(formatter, null);

    Note that the formatter and parser can be created to handle non-default Locale and Chronology as needed.

    Parameters:

    formatter - An instance of DateTimeFormatter which will be used for formatting by the toString() method. If null then a default formatter will be used.

    public LocalDateTimeStringConverter(FormatStyle dateStyle,
                                        FormatStyle timeStyle,
                                        Locale locale,
                                        Chronology chronology)

    Create a StringConverter for LocalDateTime values using a default formatter and parser, which will be based on the supplied FormatStyles, Locale, and Chronology.

    Parameters:

    dateStyle - The FormatStyle that will be used by the default formatter and parser for the date. If null then FormatStyle.SHORT will be used.

• Method Detail

  • fromString

    public LocalDateTime fromString(String value)

    Specified by:

    fromString in class StringConverter<LocalDateTime>

    Returns:

    an object representation of the string passed in.

  • toString

    public String toString(LocalDateTime value)

    Converts the object provided into its string form. Format of the returned string is defined by the specific converter.

    Specified by:

    toString in class StringConverter<LocalDateTime>

    Returns:

    a string representation of the object passed in.
