Package org.joda.time

Class LocalTime.Property

java.lang.Object

org.joda.time.field.AbstractReadableInstantFieldProperty

org.joda.time.LocalTime.Property

All Implemented Interfaces:

java.io.Serializable

Enclosing class:

LocalTime

public static final class LocalTime.Property
extends AbstractReadableInstantFieldProperty

LocalTime.Property binds a LocalTime to a DateTimeField allowing powerful datetime functionality to be easily accessed.

The simplest use of this class is as an alternative get method, here used to get the minute '30'.

 LocalTime dt = new LocalTime(12, 30);
 int year = dt.minuteOfHour().get();
 

Methods are also provided that allow time modification. These return new instances of LocalTime - they do not modify the original. The example below yields two independent immutable date objects 2 hours apart.

 LocalTime dt1230 = new LocalTime(12, 30);
 LocalTime dt1430 = dt1230.hourOfDay().setCopy(14);
 

LocalTime.Property itself is thread-safe and immutable, as well as the LocalTime being operated on.

1.3

Method Detail

getField

public DateTimeField getField()

Gets the field being used.

Specified by:

getField in class AbstractReadableInstantFieldProperty

Returns:

the field

getMillis

protected long getMillis()

Gets the milliseconds of the time that this property is linked to.

Specified by:

getMillis in class AbstractReadableInstantFieldProperty

Returns:

the milliseconds

getChronology

protected Chronology getChronology()

Gets the chronology of the datetime that this property is linked to.

Overrides:

getChronology in class AbstractReadableInstantFieldProperty

Returns:

the chronology

Since:

1.4

getLocalTime

public LocalTime getLocalTime()

Gets the LocalTime object linked to this property.

Returns:

the linked LocalTime

addCopy

public LocalTime addCopy(int value)

Adds to this field in a copy of this LocalTime.

The LocalTime attached to this property is unchanged by this call.

Parameters:

value - the value to add to the field in the copy

Returns:

a copy of the LocalTime with the field value changed

addCopy

public LocalTime addCopy(long value)

Adds to this field in a copy of this LocalTime. If the addition exceeds the maximum value (eg. 23:59) it will wrap to the minimum value (eg. 00:00).

The LocalTime attached to this property is unchanged by this call.

Parameters:

value - the value to add to the field in the copy

Returns:

a copy of the LocalTime with the field value changed

addNoWrapToCopy

public LocalTime addNoWrapToCopy(int value)

Adds to this field in a copy of this LocalTime. If the addition exceeds the maximum value (eg. 23:59) then an exception will be thrown. Contrast this behaviour to addCopy(int).

The LocalTime attached to this property is unchanged by this call.

Parameters:

value - the value to add to the field in the copy

Returns:

a copy of the LocalTime with the field value changed

Throws:

java.lang.IllegalArgumentException - if the result is invalid

addWrapFieldToCopy

public LocalTime addWrapFieldToCopy(int value)

Adds to this field, possibly wrapped, in a copy of this LocalTime. A field wrapped operation only changes this field. Thus 10:59 plusWrapField one minute goes to 10:00.

The LocalTime attached to this property is unchanged by this call.

Parameters:

value - the value to add to the field in the copy

Returns:

a copy of the LocalTime with the field value changed

Throws:

java.lang.IllegalArgumentException - if the value isn't valid

setCopy

public LocalTime setCopy(int value)

Sets this field in a copy of the LocalTime.

The LocalTime attached to this property is unchanged by this call.

Parameters:

value - the value to set the field in the copy to

Returns:

a copy of the LocalTime with the field value changed

Throws:

java.lang.IllegalArgumentException - if the value isn't valid

setCopy

public LocalTime setCopy(java.lang.String text,
                         java.util.Locale locale)

Sets this field in a copy of the LocalTime to a parsed text value.

The LocalTime attached to this property is unchanged by this call.

Parameters:

text - the text value to set

locale - optional locale to use for selecting a text symbol

Returns:

a copy of the LocalTime with the field value changed

Throws:

java.lang.IllegalArgumentException - if the text value isn't valid

setCopy

public LocalTime setCopy(java.lang.String text)

Sets this field in a copy of the LocalTime to a parsed text value.

The LocalTime attached to this property is unchanged by this call.

Parameters:

text - the text value to set

Returns:

a copy of the LocalTime with the field value changed

Throws:

java.lang.IllegalArgumentException - if the text value isn't valid

withMaximumValue

public LocalTime withMaximumValue()

Returns a new LocalTime with this field set to the maximum value for this field.

The LocalTime attached to this property is unchanged by this call.

Returns:

a copy of the LocalTime with this field set to its maximum

withMinimumValue

public LocalTime withMinimumValue()

Returns a new LocalTime with this field set to the minimum value for this field.

The LocalTime attached to this property is unchanged by this call.

Returns:

a copy of the LocalTime with this field set to its minimum

roundFloorCopy

public LocalTime roundFloorCopy()

Rounds to the lowest whole unit of this field on a copy of this LocalTime.

For example, rounding floor on the hourOfDay field of a LocalTime where the time is 10:30 would result in new LocalTime with the time of 10:00.

Returns:

a copy of the LocalTime with the field value changed

roundCeilingCopy

public LocalTime roundCeilingCopy()

Rounds to the highest whole unit of this field on a copy of this LocalTime.

For example, rounding floor on the hourOfDay field of a LocalTime where the time is 10:30 would result in new LocalTime with the time of 11:00.

Returns:

a copy of the LocalTime with the field value changed

roundHalfFloorCopy

public LocalTime roundHalfFloorCopy()

Rounds to the nearest whole unit of this field on a copy of this LocalTime, favoring the floor if halfway.

Returns:

a copy of the LocalTime with the field value changed

roundHalfCeilingCopy

public LocalTime roundHalfCeilingCopy()

Rounds to the nearest whole unit of this field on a copy of this LocalTime, favoring the ceiling if halfway.

Returns:

a copy of the LocalTime with the field value changed

roundHalfEvenCopy

public LocalTime roundHalfEvenCopy()

Rounds to the nearest whole unit of this field on a copy of this LocalTime. If halfway, the ceiling is favored over the floor only if it makes this field's value even.

Returns:

a copy of the LocalTime with the field value changed
