public final class Weeks
An immutable time period representing a number of weeks.
Weeks
is an immutable period that can only store weeks.
It does not store years, months or hours for example. As such it is a
typesafe way of representing a number of weeks in an application.
The number of weeks is set in the constructor, and may be queried using
getWeeks()
. Basic mathematical operations are provided 
plus()
, minus()
, multipliedBy()
and
dividedBy()
.
Weeks
is threadsafe and immutable.

Method Detail 

public static Weeks weeks(int weeks)
Weeks
that may be cached.
Weeks
is immutable, so instances can be cached and shared.
This factory method provides access to shared instances.
weeks
 the number of weeks to obtain an instance for
public static Weeks weeksBetween(ReadableInstant start, ReadableInstant end)
Weeks
representing the number of whole weeks
between the two specified datetimes.
start
 the start instant, must not be nullend
 the end instant, must not be null
IllegalArgumentException
 if the instants are null or invalidpublic static Weeks weeksBetween(ReadablePartial start, ReadablePartial end)
Weeks
representing the number of whole weeks
between the two specified partial datetimes.
The two partials must contain the same fields, for example you can specify
two LocalDate
objects.
start
 the start partial date, must not be nullend
 the end partial date, must not be null
IllegalArgumentException
 if the partials are null or invalidpublic static Weeks weeksIn(ReadableInterval interval)
Weeks
representing the number of whole weeks
in the specified interval.
interval
 the interval to extract weeks from, null returns zero
IllegalArgumentException
 if the partials are null or invalidpublic static Weeks standardWeeksIn(ReadablePeriod period)
Weeks
representing the number of complete
standard length weeks in the specified period.
This factory method converts all fields from the period to hours using standardised durations for each field. Only those fields which have a precise duration in the ISO UTC chronology can be converted.
period
 the period to get the number of hours from, null returns zero
IllegalArgumentException
 if the period contains imprecise duration valuespublic static Weeks parseWeeks(String periodStr)
Weeks
by parsing a string in the ISO8601 format 'PnW'.
The parse will accept the full ISO syntax of PnYnMnWnDTnHnMnS however only the weeks component may be nonzero. If any other component is nonzero, an exception will be thrown.
periodStr
 the period string, null returns zero
IllegalArgumentException
 if the string format is invalidpublic DurationFieldType getFieldType()

public Days toStandardDays()
This method allows you to convert between different types of period. However to achieve this it makes the assumption that all weeks are 7 days long. This may not be true for some unusual chronologies. However, it is included as it is a useful operation for many applications and business rules.
ArithmeticException
 if the number of days is too large to be representedpublic Hours toStandardHours()
This method allows you to convert between different types of period. However to achieve this it makes the assumption that all weeks are 7 days long and all days are 24 hours long. This is not true when daylight savings is considered and may also not be true for some unusual chronologies. However, it is included as it is a useful operation for many applications and business rules.
ArithmeticException
 if the number of hours is too large to be representedpublic Minutes toStandardMinutes()
This method allows you to convert between different types of period. However to achieve this it makes the assumption that all weeks are 7 days long, all days are 24 hours long and all hours are 60 minutes long. This is not true when daylight savings is considered and may also not be true for some unusual chronologies. However, it is included as it is a useful operation for many applications and business rules.
ArithmeticException
 if the number of minutes is too large to be representedpublic Seconds toStandardSeconds()
This method allows you to convert between different types of period. However to achieve this it makes the assumption that all weeks are 7 days long, all days are 24 hours long, all hours are 60 minutes long and all minutes are 60 seconds long. This is not true when daylight savings is considered and may also not be true for some unusual chronologies. However, it is included as it is a useful operation for many applications and business rules.
ArithmeticException
 if the number of seconds is too large to be representedpublic Duration toStandardDuration()
This method allows you to convert from a period to a duration. However to achieve this it makes the assumption that all weeks are 7 days long, all days are 24 hours long, all hours are 60 minutes long and all minutes are 60 seconds long. This is not true when daylight savings time is considered, and may also not be true for some unusual chronologies. However, it is included as it is a useful operation for many applications and business rules.
