public final class Minutes
extends BaseSingleFieldPeriod

An immutable time period representing a number of minutes.

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

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

Minutes is thread-safe and immutable.

Method Detail

minutes

public static Minutes minutes(int minutes)

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

Parameters:

minutes - the number of minutes to obtain an instance for

Returns:

the instance of Minutes

minutesBetween

public static Minutes minutesBetween(ReadableInstant start,
                                     ReadableInstant end)

Creates a Minutes representing the number of whole minutes 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 minutes

Throws:

java.lang.IllegalArgumentException - if the instants are null or invalid

minutesBetween

public static Minutes minutesBetween(ReadablePartial start,
                                     ReadablePartial end)

Creates a Minutes representing the number of whole minutes 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 minutes

Throws:

java.lang.IllegalArgumentException - if the partials are null or invalid

minutesIn

public static Minutes minutesIn(ReadableInterval interval)

Creates a Minutes representing the number of whole minutes in the specified interval.

Parameters:

interval - the interval to extract minutes from, null returns zero

Returns:

the period in minutes

Throws:

java.lang.IllegalArgumentException - if the partials are null or invalid

standardMinutesIn

public static Minutes standardMinutesIn(ReadablePeriod period)

Creates a new Minutes representing the number of complete standard length minutes in the specified period.

This factory method converts all fields from the period to minutes 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 days.
• 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 minutes from, null returns zero

Returns:

the period in minutes

Throws:

java.lang.IllegalArgumentException - if the period contains imprecise duration values

parseMinutes

public static Minutes parseMinutes(java.lang.String periodStr)

Creates a new Minutes by parsing a string in the ISO8601 format 'PTnM'.

The parse will accept the full ISO syntax of PnYnMnWnDTnHnMnS however only the minutes 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 minutes

Throws:

java.lang.IllegalArgumentException - if the string format is invalid

getFieldType

public DurationFieldType getFieldType()

Gets the duration field type, which is minutes.

Specified by:

getFieldType in class BaseSingleFieldPeriod

Returns:

the period type

getPeriodType

public PeriodType getPeriodType()

Gets the period type, which is minutes.

Specified by:

getPeriodType in interface ReadablePeriod

Specified by:

getPeriodType in class BaseSingleFieldPeriod

Returns:

the period type

toStandardWeeks

public Weeks toStandardWeeks()

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

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.

Returns:

a period representing the number of whole weeks for this number of minutes

toStandardDays

public Days toStandardDays()

Converts this period in minutes to a period in days assuming a 24 hour day and 60 minute hour.

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 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.

Returns:

a period representing the number of whole days for this number of minutes

toStandardHours

public Hours toStandardHours()

Converts this period in minutes to a period in hours assuming a 60 minute hour.

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. 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 minutes

toStandardSeconds

public Seconds toStandardSeconds()

Converts this period in minutes to a period in seconds 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 seconds for this number of minutes

Throws:

java.lang.ArithmeticException - if the number of seconds is too large to be represented

toStandardDuration

public Duration toStandardDuration()

Converts this period in minutes to a duration in milliseconds assuming a 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 minutes are 60 seconds long. This might not be true for an unusual chronology, for example one that takes leap seconds into account. However, the method is included as it is a useful operation for many applications and business rules.

Returns:

a duration equivalent to this number of minutes
