          org.joda.time.LocalTime

All Implemented Interfaces:

Serializable, Comparable<ReadablePartial>, ReadablePartial

public final class LocalTime
extends BaseLocal
implements ReadablePartial, Serializable

LocalTime is an immutable time class representing a time without a time zone.

LocalTime implements the ReadablePartial interface. To do this, the interface methods focus on the key fields - HourOfDay, MinuteOfHour, SecondOfMinute and MillisOfSecond. However, all time fields may in fact be queried.

Calculations on LocalTime are performed using a Chronology. This chronology will be set internally to be in the UTC time zone for all calculations.

Each individual field can be queried in two ways:

• getHourOfDay()
• hourOfDay().get()

The second technique also provides access to other useful methods on the field:

• numeric value
• text value
• short text value
• maximum/minimum values
• add/subtract
• set
• rounding

LocalTime is thread-safe and immutable, provided that the Chronology is as well. All standard Chronology classes supplied are thread-safe and immutable.

2.0

fromMillisOfDay

public static LocalTime fromMillisOfDay(long millisOfDay)

Constructs a LocalTime from the specified millis of day using the ISO chronology.

The millisOfDay value may exceed the number of millis in one day, but additional days will be ignored. This method uses the UTC time zone internally.

Parameters:

millisOfDay - the number of milliseconds into a day to convert

fromMillisOfDay

public static LocalTime fromMillisOfDay(long millisOfDay,
                                        Chronology chrono)

Constructs a LocalTime from the specified millis of day using the specified chronology.

The millisOfDay value may exceed the number of millis in one day, but additional days will be ignored. This method uses the UTC time zone internally.

Parameters:

millisOfDay - the number of milliseconds into a day to convert

chrono - the chronology, null means ISO chronology

fromCalendarFields

public static LocalTime fromCalendarFields(Calendar calendar)

Constructs a LocalTime from a java.util.Calendar using exactly the same field values.

Each field is queried from the Calendar and assigned to the LocalTime. This is useful if you have been using the Calendar as a local time, ignoring the zone.

One advantage of this method is that this method is unaffected if the version of the time zone data differs between the JDK and Joda-Time. That is because the local field values are transferred, calculated using the JDK time zone data and without using the Joda-Time time zone data.

This factory method ignores the type of the calendar and always creates a LocalTime with ISO chronology. It is expected that you will only pass in instances of GregorianCalendar however this is not validated.

Parameters:

calendar - the Calendar to extract fields from

Returns:

the created LocalTime

Throws:

IllegalArgumentException - if the calendar is null

IllegalArgumentException - if the date is invalid for the ISO chronology

fromDateFields

public static LocalTime fromDateFields(Date date)

Constructs a LocalTime from a java.util.Date using exactly the same field values.

Each field is queried from the Date and assigned to the LocalTime. This is useful if you have been using the Date as a local time, ignoring the zone.

One advantage of this method is that this method is unaffected if the version of the time zone data differs between the JDK and Joda-Time. That is because the local field values are transferred, calculated using the JDK time zone data and without using the Joda-Time time zone data.

This factory method always creates a LocalTime with ISO chronology.

Parameters:

date - the Date to extract fields from

Returns:

the created LocalTime

Throws:

IllegalArgumentException - if the calendar is null

IllegalArgumentException - if the date is invalid for the ISO chronology

These lines are equivalent:

 LocalTime added = dt.plusHours(6);
 LocalTime added = dt.withFieldAdded(DurationFieldType.hours(), 6);
 

Parameters:

Returns a copy of this time with the specified period added.
