public class RelativeDate
extends DataClass

This class is used used to specify a datetime offset within SmartGWT, for example for use in the RelativeDateItem class.

The value attribute is set to a string which specifies the offset from some base date (typically the current date as returned from a call to new Date();). See RelativeDate(String) for details on the expected format of the string passed in.

DateRange.setRelativeStartDate(RelativeDate), DateRange.setRelativeEndDate(RelativeDate)

Constructor Detail

RelativeDate

public RelativeDate(java.lang.String value)

The value attribute of a RelativeDate object is a string that should be specified in one of 2 formats:

There are a number of standard preset shortcut date-offset strings. These include the following

• $now - this moment
• $today - the current day. By default this resolves to the start of the current day though an explicit +link{RelativeDateRangePosition} may be used to specify the end of the current day.
• $startOfToday - the start of today
• $endOfToday - the end of today (one millisecond before the $startOfTomorrow)
• $yesterday - the previous day.
• $startOfYesterday - the start of yesterday
• $endOfYesterday - the end of yesterday (one millisecond before the $startOfToday)
• $tomorrow - the following day
• $startOfTomorrow - the start of tomorrow
• $endOfTomorrow - the end of tomorrow
• $startOfWeek - the start of the current week
• $endOfWeek - the end of the current week
• $startOfMonth - the start of the current month
• $endOfMonth - the end of the current month
• $startOfYear - the start of the current year
• $endOfYear - the end of the current year

Note that some shortcuts indicate a time period but do not directly indicate whether the value refers to the start or end of the time period in question. This ambiguity can be resolved by specifying an explicit RelativeDateRangePosition when calling APIs that convert from RelativeDates to absolute date values. This is the case for $today, $tomorrow, $yesterday, $weekAgo, $weekFromNow, $monthAgo and $monthFromNow. If a range position is not explicitly passed, these will all default to the start of the day in question.

Alternatively the value can be a special RelativeDateString comprised of the following parts:

• direction: the direction in which the quantity applies - one of + or -
• quantity: the number of units of time to apply - a number
• timeUnit: an abbreviated timeUnit to use - one of ms/MS (millisecond), s/S (second), mn/MN (minute), h/H (hour), d/D (day), w/W (week), m/M (month), q/Q (quarter, 3-months), y/Y (year), dc/DC (decade) or c/C (century).
  The timeUnit is case sensitive. A lowercase timeUnit implies an exact offset, so +1d refers to the current date / time increased by exactly 24 hours. If the timeUnit is uppercase, it refers to the start or end boundary of the period of time in question, so +1D would refer to the end of the day (23:39:59:999) tomorrow, and -1D would refer to the start of the day (00:00:00:000) yesterday.
• [qualifier]: an optional timeUnit encapsulated in square-brackets and used to offset the calculation - eg. if +1d is "plus one day", +1d[W] is "plus one day from the end of the current week". You may also specify another complete RelativeDateString as the [qualifier], which offers more control - eg, +1d[+1W] indicates "plus one day from the end of NEXT week".

This format is very flexible. Here are a few example relative date strings:
+0D: End of today. There are often multiple ways to represent the same time using this system - for example this could also be written as -1ms[+1D]
-0D: Beginning of today.
+1W: End of next week.
+1ms[+0W]: Beginning of next week.
+1w[-0D]: Beginning of the current day of next week.
