Class Seconds

java.lang.Object
  org.joda.time.base.BaseSingleFieldPeriod
      org.joda.time.Seconds

All Implemented Interfaces:: Serializable, Comparable<BaseSingleFieldPeriod>, ReadablePeriod

public final class Seconds
extends BaseSingleFieldPeriod
extends BaseSingleFieldPeriod

An immutable time period representing a number of seconds.

Seconds is an immutable period that can only store seconds. It does not store years, months or hours for example. As such it is a type-safe way of representing a number of seconds in an application.

The number of seconds is set in the constructor, and may be queried using getSeconds(). Basic mathematical operations are provided - plus(), minus(), multipliedBy() and dividedBy().

Seconds is thread-safe and immutable.

Since:: 1.4

Method Detail

seconds

public static Seconds seconds(int seconds)

Obtains an instance of Seconds that may be cached. Seconds is immutable, so instances can be cached and shared. This factory method provides access to shared instances.

Parameters:: seconds - the number of seconds to obtain an instance for
Returns:: the instance of Seconds

secondsBetween

public static Seconds secondsBetween(ReadableInstant start,
                                     ReadableInstant end)

Creates a Seconds representing the number of whole seconds between the two specified datetimes.

Parameters:: start - the start instant, must not be null; end - the end instant, must not be null
Returns:: the period in seconds
Throws:: IllegalArgumentException - if the instants are null or invalid

secondsBetween

public static Seconds secondsBetween(ReadablePartial start,
                                     ReadablePartial end)

Creates a Seconds representing the number of whole seconds between the two specified partial datetimes.

The two partials must contain the same fields, for example you can specify two LocalTime objects.

Parameters:: start - the start partial date, must not be null; end - the end partial date, must not be null
Returns:: the period in seconds
Throws:: IllegalArgumentException - if the partials are null or invalid

secondsIn

public static Seconds secondsIn(ReadableInterval interval)

Creates a Seconds representing the number of whole seconds in the specified interval.

Parameters:: interval - the interval to extract seconds from, null returns zero
Returns:: the period in seconds
Throws:: IllegalArgumentException - if the partials are null or invalid

standardSecondsIn

public static Seconds standardSecondsIn(ReadablePeriod period)

Creates a new Seconds representing the number of complete standard length seconds 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.

One week consists of 7 seconds.
One day consists of 24 hours.
One hour consists of 60 minutes.
One minute consists of 60 seconds.
One second consists of 1000 milliseconds.

Months and Years are imprecise and periods containing these values cannot be converted.

Parameters:: period - the period to get the number of hours from, null returns zero
Returns:: the period in seconds
Throws:: IllegalArgumentException - if the period contains imprecise duration values

parseSeconds

public static Seconds parseSeconds(String periodStr)

Creates a new Seconds by parsing a string in the ISO8601 format 'PTnS'.

The parse will accept the full ISO syntax of PnYnMnWnDTnHnMnS however only the seconds component may be non-zero. If any other component is non-zero, an exception will be thrown.

Parameters:: periodStr - the period string, null returns zero
Returns:: the period in seconds
Throws:: IllegalArgumentException - if the string format is invalid

getFieldType

public DurationFieldType getFieldType()

Gets the duration field type, which is seconds.

Specified by:: getFieldType in class BaseSingleFieldPeriod

Returns:: the period type

getPeriodType

public PeriodType getPeriodType()

Gets the period type, which is seconds.

Specified by:: getPeriodType in interface ReadablePeriod
Specified by:: getPeriodType in class BaseSingleFieldPeriod

Returns:: the period type

toStandardWeeks

public Weeks toStandardWeeks()

Converts this period in seconds to a period in weeks assuming a 7 day week, 24 hour day, 60 minute hour and 60 second minute.

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 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.

Returns:: a period representing the number of whole weeks for this number of seconds

toStandardDays

public Days toStandardDays()

Converts this period in seconds to a period in days assuming a 24 hour day, 60 minute hour and 60 second minute.

This method allows you to convert between different types of period. However to achieve this it makes the assumption that 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.

Returns:: a period representing the number of days for this number of seconds

toStandardHours

public Hours toStandardHours()

Converts this period in seconds to a period in hours assuming a 60 minute hour and 60 second minute.

This method allows you to convert between different types of period. However to achieve this it makes the assumption that all hours are 60 minutes long and all minutes are 60 seconds 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.

Returns:: a period representing the number of hours for this number of seconds

toStandardMinutes

public Minutes toStandardMinutes()

Converts this period in seconds to a period in minutes assuming a 60 second minute.

This method allows you to convert between different types of period. However to achieve this it makes the assumption that all minutes are 60 seconds 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.

Returns:: a period representing the number of minutes for this number of seconds

toStandardDuration

public Duration toStandardDuration()

Converts this period in seconds to a duration in milliseconds assuming a 24 hour day, 60 minute hour and 60 second minute.

This method allows you to convert from a period to a duration. However to achieve this it makes the assumption that all seconds are 24 hours long, all hours are 60 minutes and all minutes are 60 seconds. 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.

Returns:: a duration equivalent to this number of seconds

getSeconds

public int getSeconds()

Gets the number of seconds that this period represents.

Returns:: the number of seconds in the period
