getType
Description copied from class:DurationFieldGet the type of the field.- Specified by:
getTypein classDurationField- Returns:
- field type
-
getName
Description copied from class:DurationFieldGet the name of the field.By convention, names are plural.
- Specified by:
getNamein classDurationField- Returns:
- field name
-
isSupported
public boolean isSupported()Returns true as this field is supported.- Specified by:
isSupportedin classDurationField- Returns:
- true always
-
isPrecise
public final boolean isPrecise()Returns true as this field is precise.- Specified by:
isPrecisein classDurationField- Returns:
- true always
- See Also:
-
getUnitMillis
public final long getUnitMillis()Returns the amount of milliseconds per unit value of this field.- Specified by:
getUnitMillisin classDurationField- Returns:
- one always

getValue
public int getValue(long duration) Description copied from class:DurationFieldGet the value of this field from the milliseconds, which is approximate if this field is imprecise.- Specified by:
getValuein classDurationField- Parameters:
duration- the milliseconds to query, which may be negative- Returns:
- the value of the field, in the units of the field, which may be negative
-
getValueAsLong
public long getValueAsLong(long duration) Description copied from class:DurationFieldGet the value of this field from the milliseconds, which is approximate if this field is imprecise.- Specified by:
getValueAsLongin classDurationField- Parameters:
duration- the milliseconds to query, which may be negative- Returns:
- the value of the field, in the units of the field, which may be negative
-
getValue
public int getValue(long duration, long instant) Description copied from class:DurationFieldGet the value of this field from the milliseconds relative to an instant. For precise fields this method produces the same result as for the single argument get method.If the millisecond duration is positive, then the instant is treated as a "start instant". If negative, the instant is treated as an "end instant".
- Specified by:
getValuein classDurationField- Parameters:
duration- the milliseconds to query, which may be negativeinstant- the start instant to calculate relative to- Returns:
- the value of the field, in the units of the field, which may be negative
-
getValueAsLong
public long getValueAsLong(long duration, long instant) Description copied from class:DurationFieldGet the value of this field from the milliseconds relative to an instant. For precise fields this method produces the same result as for the single argument get method.If the millisecond duration is positive, then the instant is treated as a "start instant". If negative, the instant is treated as an "end instant".
- Specified by:
getValueAsLongin classDurationField- Parameters:
duration- the milliseconds to query, which may be negativeinstant- the start instant to calculate relative to- Returns:
- the value of the field, in the units of the field, which may be negative
-
getMillis
public long getMillis(int value) Description copied from class:DurationFieldGet the millisecond duration of this field from its value, which is approximate if this field is imprecise.- Specified by:
getMillisin classDurationField- Parameters:
value- the value of the field, which may be negative- Returns:
- the milliseconds that the field represents, which may be negative
-
getMillis
public long getMillis(long value) Description copied from class:DurationFieldGet the millisecond duration of this field from its value, which is approximate if this field is imprecise.- Specified by:
getMillisin classDurationField- Parameters:
value- the value of the field, which may be negative- Returns:
- the milliseconds that the field represents, which may be negative
-
getMillis
public long getMillis(int value, long instant) Description copied from class:DurationFieldGet the millisecond duration of this field from its value relative to an instant. For precise fields this method produces the same result as for the single argument getMillis method.If the value is positive, then the instant is treated as a "start instant". If negative, the instant is treated as an "end instant".
- Specified by:
getMillisin classDurationField- Parameters:
value- the value of the field, which may be negativeinstant- the instant to calculate relative to- Returns:
- the millisecond duration that the field represents, which may be negative
-
getMillis
public long getMillis(long value, long instant) Description copied from class:DurationFieldGet the millisecond duration of this field from its value relative to an instant. For precise fields this method produces the same result as for the single argument getMillis method.If the value is positive, then the instant is treated as a "start instant". If negative, the instant is treated as an "end instant".
- Specified by:
getMillisin classDurationField- Parameters:
value- the value of the field, which may be negativeinstant- the instant to calculate relative to- Returns:
- the millisecond duration that the field represents, which may be negative
-
add
public long add(long instant, int value) Description copied from class:DurationFieldAdds a duration value (which may be negative) to the instant.- Specified by:
addin classDurationField- Parameters:
instant- the milliseconds from 1970-01-01T00:00:00Z to add tovalue- the value to add, in the units of the field- Returns:
- the updated milliseconds
-
add
public long add(long instant, long value) Description copied from class:DurationFieldAdds a duration value (which may be negative) to the instant.- Specified by:
addin classDurationField- Parameters:
instant- the milliseconds from 1970-01-01T00:00:00Z to add tovalue- the value to add, in the units of the field- Returns:
- the updated milliseconds
-
getDifference
public int getDifference(long minuendInstant, long subtrahendInstant) Description copied from class:DurationFieldComputes the difference between two instants, as measured in the units of this field. Any fractional units are dropped from the result. Calling getDifference reverses the effect of calling add. In the following code:long instant = ... int v = ... int age = getDifference(add(instant, v), instant);
The value 'age' is the same as the value 'v'.- Specified by:
getDifferencein classDurationField- Parameters:
minuendInstant- the milliseconds from 1970-01-01T00:00:00Z to subtract fromsubtrahendInstant- the milliseconds from 1970-01-01T00:00:00Z to subtract off the minuend- Returns:
- the difference in the units of this field
-
getDifferenceAsLong
public long getDifferenceAsLong(long minuendInstant, long subtrahendInstant) Description copied from class:DurationFieldComputes the difference between two instants, as measured in the units of this field. Any fractional units are dropped from the result. Calling getDifference reverses the effect of calling add. In the following code:long instant = ... long v = ... long age = getDifferenceAsLong(add(instant, v), instant);
The value 'age' is the same as the value 'v'.- Specified by:
getDifferenceAsLongin classDurationField- Parameters:
minuendInstant- the milliseconds from 1970-01-01T00:00:00Z to subtract fromsubtrahendInstant- the milliseconds from 1970-01-01T00:00:00Z to subtract off the minuend- Returns:
- the difference in the units of this field
-
