Package org.joda.time

Class MutableDateTime.Property

java.lang.Object

org.joda.time.field.AbstractReadableInstantFieldProperty

org.joda.time.MutableDateTime.Property

All Implemented Interfaces:

java.io.Serializable

Enclosing class:

MutableDateTime

public static final class MutableDateTime.Property
extends AbstractReadableInstantFieldProperty

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

The example below shows how to use the property to change the value of a MutableDateTime object.

 MutableDateTime dt = new MutableDateTime(1972, 12, 3, 13, 32, 19, 123);
 dt.year().add(20);
 dt.second().roundFloor().minute().set(10);
 

MutableDateTime.Propery itself is thread-safe and immutable, but the MutableDateTime being operated on is not.

Since:

1.0

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 datetime 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

getMutableDateTime

public MutableDateTime getMutableDateTime()

Gets the mutable datetime being used.

Returns:

the mutable datetime

add

public MutableDateTime add(int value)

Adds a value to the millis value.

Parameters:

value - the value to add

Returns:

the mutable datetime being used, so calls can be chained

See Also:

DateTimeField.add(long,int)

add

public MutableDateTime add(long value)

Adds a value to the millis value.

Parameters:

value - the value to add

Returns:

the mutable datetime being used, so calls can be chained

See Also:

DateTimeField.add(long,long)

addWrapField

public MutableDateTime addWrapField(int value)

Adds a value, possibly wrapped, to the millis value.

Parameters:

value - the value to add

Returns:

the mutable datetime being used, so calls can be chained

See Also:

DateTimeField.addWrapField(long, int)

set

public MutableDateTime set(int value)

Sets a value.

Parameters:

value - the value to set.

Returns:

the mutable datetime being used, so calls can be chained

See Also:

DateTimeField.set(long,int)

set

public MutableDateTime set(java.lang.String text,
                           java.util.Locale locale)

Sets a text value.

Parameters:

text - the text value to set

locale - optional locale to use for selecting a text symbol

Returns:

the mutable datetime being used, so calls can be chained

Throws:

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

See Also:

DateTimeField.set(long,java.lang.String,java.util.Locale)

set

public MutableDateTime set(java.lang.String text)

Sets a text value.

Parameters:

text - the text value to set

Returns:

the mutable datetime being used, so calls can be chained

Throws:

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

See Also:

DateTimeField.set(long,java.lang.String)

roundFloor

public MutableDateTime roundFloor()

Round to the lowest whole unit of this field.

Returns:

the mutable datetime being used, so calls can be chained

See Also:

DateTimeField.roundFloor(long)

roundCeiling

public MutableDateTime roundCeiling()

Round to the highest whole unit of this field.

Returns:

the mutable datetime being used, so calls can be chained

See Also:

DateTimeField.roundCeiling(long)

roundHalfFloor

public MutableDateTime roundHalfFloor()

Round to the nearest whole unit of this field, favoring the floor if halfway.

Returns:

the mutable datetime being used, so calls can be chained

See Also:

DateTimeField.roundHalfFloor(long)

roundHalfCeiling

public MutableDateTime roundHalfCeiling()

Round to the nearest whole unit of this field, favoring the ceiling if halfway.

Returns:

the mutable datetime being used, so calls can be chained

See Also:

DateTimeField.roundHalfCeiling(long)

roundHalfEven

public MutableDateTime roundHalfEven()

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

Returns:

the mutable datetime being used, so calls can be chained

See Also:

DateTimeField.roundHalfEven(long)
