getValue
public int getValue(long duration, long instant)
Description copied from class:BaseDurationField
Get the value of this field from the milliseconds relative to an instant.If the milliseconds is positive, then the instant is treated as a "start instant". If negative, the instant is treated as an "end instant".
The default implementation returns
Utils.safeToInt(getAsLong(millisDuration, instant))
.- Overrides:
getValue
in classBaseDurationField
- 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:DurationField
Get 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".
- Overrides:
getValueAsLong
in classDecoratedDurationField
- 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, long instant)
Description copied from class:DurationField
Get 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".
- Overrides:
getMillis
in classDecoratedDurationField
- 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:DurationField
Get 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".
- Overrides:
getMillis
in classDecoratedDurationField
- 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 amount)
Description copied from class:DurationField
Adds a duration value (which may be negative) to the instant.- Overrides:
add
in classDecoratedDurationField
- Parameters:
instant
- the milliseconds from 1970-01-01T00:00:00Z to add toamount
- the value to add, in the units of the field- Returns:
- the updated milliseconds
-
add
public long add(long instant, long amount)
Description copied from class:DurationField
Adds a duration value (which may be negative) to the instant.- Overrides:
add
in classDecoratedDurationField
- Parameters:
instant
- the milliseconds from 1970-01-01T00:00:00Z to add toamount
- 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:DurationField
Computes 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'.- Overrides:
getDifference
in classBaseDurationField
- 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:DurationField
Computes 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'.- Overrides:
getDifferenceAsLong
in classDecoratedDurationField
- 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
