Interface ReadWritableInstant
- Comparable, ReadableInstant
- ReadWritableDateTime
- MutableDateTime
public interface ReadWritableInstant
Defines an instant in the datetime continuum that can be queried and modified.
This interface expresses the datetime as milliseconds from 1970-01-01T00:00:00Z.
The implementation of this interface will be mutable.
It may provide more advanced methods than those in the interface.
void | add(long duration) - Adds a millisecond duration to this instant.
|
void | add(DurationFieldType type, int amount) - Adds to the instant specifying the duration and multiple to add.
|
void | add(ReadableDuration duration) - Adds a duration to this instant.
|
void | add(ReadableDuration duration, int scalar) - Adds a duration to this instant specifying how many times to add.
|
void | add(ReadablePeriod period) - Adds a period to this instant.
|
void | add(ReadablePeriod period, int scalar) - Adds a period to this instant specifying how many times to add.
|
void | set(DateTimeFieldType type, int value) - Sets the value of one of the fields of the instant, such as hourOfDay.
|
void | setChronology(Chronology chronology) - Sets the chronology of the datetime, which has no effect if not applicable.
|
void | setMillis(long instant) - Sets the value as the number of milliseconds since
the epoch, 1970-01-01T00:00:00Z.
|
void | setMillis(ReadableInstant instant) - Sets the millisecond instant of this instant from another.
|
void | setZone(DateTimeZone zone) - Sets the time zone of the datetime, changing the chronology and field values.
|
void | setZoneRetainFields(DateTimeZone zone) - Sets the time zone of the datetime, changing the chronology and millisecond.

add
public void add(long duration)
Adds a millisecond duration to this instant.
This will typically change the value of ost fields.
duration
- the millis to add
add
public void add(DurationFieldType type,
int amount)
Adds to the instant specifying the duration and multiple to add.
type
- a field type, usually obtained from DateTimeFieldType, null ignoredamount
- the amount to add of this duration
add
public void add(ReadableDuration duration)
Adds a duration to this instant.
This will typically change the value of most fields.
duration
- the duration to add, null means add zero
add
public void add(ReadableDuration duration,
int scalar)
Adds a duration to this instant specifying how many times to add.
This will typically change the value of most fields.
duration
- the duration to add, null means add zeroscalar
- direction and amount to add, which may be negative
add
public void add(ReadablePeriod period)
Adds a period to this instant.
This will typically change the value of most fields.
period
- the period to add, null means add zero
add
public void add(ReadablePeriod period,
int scalar)
Adds a period to this instant specifying how many times to add.
This will typically change the value of most fields.
period
- the period to add, null means add zeroscalar
- direction and amount to add, which may be negative
set
public void set(DateTimeFieldType type,
int value)
Sets the value of one of the fields of the instant, such as hourOfDay.
type
- a field type, usually obtained from DateTimeFieldType, null ignoredvalue
- the value to set the field to
setChronology
public void setChronology(Chronology chronology)
Sets the chronology of the datetime, which has no effect if not applicable.
chronology
- the chronology to use, null means ISOChronology in default zone
setMillis
public void setMillis(long instant)
Sets the value as the number of milliseconds since
the epoch, 1970-01-01T00:00:00Z.
instant
- the milliseconds since 1970-01-01T00:00:00Z to set the
instant to
setMillis
public void setMillis(ReadableInstant instant)
Sets the millisecond instant of this instant from another.
This method does not change the chronology of this instant, just the
millisecond instant.
instant
- the instant to use, null means now
setZone
public void setZone(DateTimeZone zone)
Sets the time zone of the datetime, changing the chronology and field values.
Changing the zone using this method retains the millisecond instant.
The millisecond instant is adjusted in the new zone to compensate.
chronology. Setting the time zone does not affect the millisecond value
of this instant.
If the chronology already has this time zone, no change occurs.
zone
- the time zone to use, null means default zone
setZoneRetainFields
public void setZoneRetainFields(DateTimeZone zone)
Sets the time zone of the datetime, changing the chronology and millisecond.
Changing the zone using this method retains the field values.
The millisecond instant is adjusted in the new zone to compensate.
If the chronology already has this time zone, no change occurs.
zone
- the time zone to use, null means default zone
