  • Constructor Details

    • LocalDateStringConverter

      public LocalDateStringConverter()
      Create a StringConverter for LocalDate values, using a default formatter and parser based on IsoChronology, FormatStyle.SHORT, 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 leniently as expected in these locales.

    • LocalDateStringConverter

      public LocalDateStringConverter(FormatStyle dateStyle)
      Create a StringConverter for LocalDate values, using a default formatter and parser based on IsoChronology, the specified FormatStyle, and the user's Locale.
      Parameters:
      dateStyle - The FormatStyle that will be used by the default formatter and parser. If null then FormatStyle.SHORT will be used.

    • LocalDateStringConverter

      public LocalDateStringConverter(DateTimeFormatter formatter, DateTimeFormatter parser)
      Create a {#link StringConverter} for LocalDate values using the supplied formatter and parser.

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

       String pattern = "yyyy-MM-dd";
 DateTimeFormatter formatter = DateTimeFormatter.ofPattern(pattern);
 StringConverter<LocalDate> converter =
     DateTimeStringConverter.getLocalDateStringConverter(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 that will be used for formatting by the toString() method. If null then a default formatter will be used.
      parser - An instance of DateTimeFormatter that will be used for parsing by the fromString() method. This can be identical to formatter. If null then formatter will be used, and if that is also null, then a default parser will be used.

    • LocalDateStringConverter

      public LocalDateStringConverter(FormatStyle dateStyle, Locale locale, Chronology chronology)
      Create a StringConverter for LocalDate values using a default formatter and parser, which will be based on the supplied FormatStyle, Locale, and Chronology.
      Parameters:
      dateStyle - The FormatStyle that will be used by the default formatter and parser. If null then FormatStyle.SHORT will be used.
      locale - The Locale that will be used by the default formatter and parser. If null then Locale.getDefault(Locale.Category.FORMAT) will be used.
      chronology - The Chronology that will be used by the default formatter and parser. If null then IsoChronology.INSTANCE will be used.

    • fromString

      public LocalDate fromString(String value)
      Converts the string provided into an object defined by the specific converter. Format of the string and type of the resulting object is defined by the specific converter.
      Specified by:
      fromString in class StringConverter<LocalDate>
      Parameters:
      value - the String to convert
      Returns:
      an object representation of the string passed in.

    • toString

      public String toString(LocalDate 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<LocalDate>
      Parameters:
      value - the object of type T to convert
      Returns:
      a string representation of the object passed in
