Methods

Modifier and Type	Method and Description
DateRangeBuilder	set(Class<? extends Date> valueClass) Configuration method which sets value class, to indicate desired class of DateRange.getStart and DateRange.getEnd methods.
DateRangeBuilder	set(Integer weekStartDay) Configuration method which set start of a week which will be used during DateRange.getStart and DateRange.getEnd calculations.
DateRangeBuilder	set(Locale locale) Configuration method which set start of a week which will be used during DateRange.getStart and DateRange.getEnd calculations from passed locale instance NOTE: This method and set(Integer) will overwrite each other so configuration which was set later will be used.
DateRangeBuilder	set(String datePattern) Configuration method which sets date pattern which will be used to parse expression NOTE: this method only will take effect if expression is in fact formatted date like "1970-01-01".
DateRangeBuilder	set(TimeZone timeZone) Configuration method which sets desired time zone which will be used to calculate DateRange.getStart and DateRange.getEnd.
DateRange	toDateRange() Returns instance of DateRange based on which configuration methods was called
