Class Overview

BasePeriod is an abstract implementation of ReadablePeriod that stores data in a PeriodType and an int[].

This class should generally not be used directly by API users. The ReadablePeriod interface should be used when different kinds of period objects are to be referenced.

BasePeriod subclasses may be mutable and not thread-safe.

Protected Constructors

protected BasePeriod (int years, int months, int weeks, int days, int hours, int minutes, int seconds, int millis, PeriodType type)

Creates a period from a set of field values.

Parameters
years amount of years in this period, which must be zero if unsupported
months amount of months in this period, which must be zero if unsupported
weeks amount of weeks in this period, which must be zero if unsupported
days amount of days in this period, which must be zero if unsupported
hours amount of hours in this period, which must be zero if unsupported
minutes amount of minutes in this period, which must be zero if unsupported
seconds amount of seconds in this period, which must be zero if unsupported
millis amount of milliseconds in this period, which must be zero if unsupported
type which set of fields this period supports
Throws
IllegalArgumentException if period type is invalid
IllegalArgumentException if an unsupported field's value is non-zero

protected BasePeriod (long startInstant, long endInstant, PeriodType type, Chronology chrono)

Creates a period from the given interval endpoints.

Parameters
startInstant interval start, in milliseconds
endInstant interval end, in milliseconds
type which set of fields this period supports, null means standard
chrono the chronology to use, null means ISO default
Throws
IllegalArgumentException if period type is invalid

protected BasePeriod (ReadableInstant startInstant, ReadableInstant endInstant, PeriodType type)

Creates a period from the given interval endpoints.

Parameters
startInstant interval start, null means now
endInstant interval end, null means now
type which set of fields this period supports, null means standard
Throws
IllegalArgumentException if period type is invalid

protected BasePeriod (ReadablePartial start, ReadablePartial end, PeriodType type)

Creates a period from the given duration and end point.

The two partials must contain the same fields, thus you can specify two LocalDate objects, or two LocalTime objects, but not one of each. As these are Partial objects, time zones have no effect on the result.

The two partials must also both be contiguous - see isContiguous(ReadablePartial) for a definition. Both LocalDate and LocalTime are contiguous.

Parameters
start the start of the period, must not be null
end the end of the period, must not be null
type which set of fields this period supports, null means standard
Throws
IllegalArgumentException if the partials are null or invalid

protected BasePeriod (ReadableInstant startInstant, ReadableDuration duration, PeriodType type)

Creates a period from the given start point and duration.

Parameters
startInstant the interval start, null means now
duration the duration of the interval, null means zero-length
type which set of fields this period supports, null means standard

protected BasePeriod (ReadableDuration duration, ReadableInstant endInstant, PeriodType type)

Creates a period from the given duration and end point.

Parameters
duration the duration of the interval, null means zero-length
endInstant the interval end, null means now
type which set of fields this period supports, null means standard

protected BasePeriod (long duration, PeriodType type, Chronology chrono)

Creates a period from the given millisecond duration, which is only really suitable for durations less than one day.

Only fields that are precise will be used. Thus the largest precise field may have a large value.

Parameters
duration the duration, in milliseconds
type which set of fields this period supports, null means standard
chrono the chronology to use, null means ISO default
Throws
IllegalArgumentException if period type is invalid

protected BasePeriod (Object period, PeriodType type, Chronology chrono)

Creates a new period based on another using the ConverterManager.

Parameters
period the period to convert
type which set of fields this period supports, null means use type from object
chrono the chronology to use, null means ISO default
Throws
IllegalArgumentException if period is invalid
IllegalArgumentException if an unsupported field's value is non-zero

protected BasePeriod (int[] values, PeriodType type)

Constructor used when we trust ourselves. Do not expose publically.

Parameters
values the values to use, not null, not cloned
type which set of fields this period supports, not null

Public Methods

public DurationFieldType getFieldType (int index)

Gets the field type at the specified index.

Parameters
index the index to retrieve
Returns
  • the field at the specified index
Throws
IndexOutOfBoundsException if the index is invalid

public PeriodType getPeriodType ()

Gets the period type.

Returns
  • the period type

public int getValue (int index)

Gets the value at the specified index.

Parameters
index the index to retrieve
Returns
  • the value of the field at the specified index
Throws
IndexOutOfBoundsException if the index is invalid

public int size ()

Gets the number of fields that this period supports.

Returns
  • the number of fields supported

public Duration toDurationFrom (ReadableInstant startInstant)

Gets the total millisecond duration of this period relative to a start instant.

This method adds the period to the specified instant in order to calculate the duration.

An instant must be supplied as the duration of a period varies. For example, a period of 1 month could vary between the equivalent of 28 and 31 days in milliseconds due to different length months. Similarly, a day can vary at Daylight Savings cutover, typically between 23 and 25 hours.

Parameters
startInstant the instant to add the period to, thus obtaining the duration
Returns
  • the total length of the period as a duration relative to the start instant
Throws
ArithmeticException if the millis exceeds the capacity of the duration

public Duration toDurationTo (ReadableInstant endInstant)

Gets the total millisecond duration of this period relative to an end instant.

This method subtracts the period from the specified instant in order to calculate the duration.

An instant must be supplied as the duration of a period varies. For example, a period of 1 month could vary between the equivalent of 28 and 31 days in milliseconds due to different length months. Similarly, a day can vary at Daylight Savings cutover, typically between 23 and 25 hours.

Parameters
endInstant the instant to subtract the period from, thus obtaining the duration
Returns
  • the total length of the period as a duration relative to the end instant
Throws
ArithmeticException if the millis exceeds the capacity of the duration
