Interface ReadableDateTime

All Superinterfaces:

java.lang.Comparable<ReadableInstant>, ReadableInstant

All Known Subinterfaces:

ReadWritableDateTime

All Known Implementing Classes:

AbstractDateTime, BaseDateTime, DateMidnight, DateTime, MutableDateTime

public interface ReadableDateTime
extends ReadableInstant

Defines an instant in time that can be queried using datetime fields.

The implementation of this interface may be mutable or immutable. This interface only gives access to retrieve data, never to change it.

Methods in your application should be defined using ReadableDateTime as a parameter if the method only wants to read the datetime, and not perform any advanced manipulations.

Method Detail

getDayOfWeek

int getDayOfWeek()

Get the day of week field value.

The values for the day of week are defined in DateTimeConstants.

Returns:

the day of week

getDayOfMonth

int getDayOfMonth()

Get the day of month field value.

Returns:

the day of month

getDayOfYear

int getDayOfYear()

Get the day of year field value.

Returns:

the day of year

getWeekOfWeekyear

int getWeekOfWeekyear()

Get the week of weekyear field value.

This field is associated with the "weekyear" via getWeekyear(). In the standard ISO8601 week algorithm, the first week of the year is that in which at least 4 days are in the year. As a result of this definition, day 1 of the first week may be in the previous year.

Returns:

the week of a week based year

getWeekyear

int getWeekyear()

Get the weekyear field value.

The weekyear is the year that matches with the weekOfWeekyear field. In the standard ISO8601 week algorithm, the first week of the year is that in which at least 4 days are in the year. As a result of this definition, day 1 of the first week may be in the previous year. The weekyear allows you to query the effective year for that day.

Returns:

the year of a week based year

getMonthOfYear

int getMonthOfYear()

Get the month of year field value.

Returns:

the month of year

getYear

int getYear()

Get the year field value.

Returns:

the year

getYearOfEra

int getYearOfEra()

Get the year of era field value.

Returns:

the year of era

getYearOfCentury

int getYearOfCentury()

Get the year of century field value.

Returns:

the year of century

getCenturyOfEra

int getCenturyOfEra()

Get the year of era field value.

Returns:

the year of era

getEra

int getEra()

Get the era field value.

Returns:

the era

getMillisOfSecond

int getMillisOfSecond()

Get the millis of second field value.

Returns:

the millis of second

getMillisOfDay

int getMillisOfDay()

Get the millis of day field value.

Returns:

the millis of day

getSecondOfMinute

int getSecondOfMinute()

Get the second of minute field value.

Returns:

Get this object as a DateTime.

If the implementation of the interface is a DateTime, it is returned directly.

Returns:

a DateTime using the same millis

toMutableDateTime

MutableDateTime toMutableDateTime()

Get this object as a MutableDateTime, always returning a new instance.

Returns:

a MutableDateTime using the same millis
