  • Constructor Details

    • DurationFormatter

      public DurationFormatter(DurationFormat.Style style)
      Create a DurationFormatter in a specific DurationFormat.Style.

      When a unit is needed but cannot be determined (for example, printing a Duration in the SIMPLE style), DurationFormat.Unit#MILLIS is used.

    • DurationFormatter

      public DurationFormatter(DurationFormat.Style style, @Nullable DurationFormat.Unit defaultUnit)
      Create a DurationFormatter in a specific DurationFormat.Style with an optional DurationFormat.Unit.

      If a defaultUnit is specified, it may be used in parsing cases when no unit is present in the string (provided the style allows for such a case). It will also be used as the representation's resolution when printing in the DurationFormat.Style.SIMPLE style. Otherwise, the style defines its default unit.

      Parameters:
      style - the DurationStyle to use
      defaultUnit - the DurationFormat.Unit to fall back to when parsing and printing
