isPrecise
public boolean isPrecise()
Description copied from class:DurationField
Is this field precise. A precise field can calculate its value from milliseconds without needing a reference date. Put another way, a precise field's unit size is not variable.- Specified by:
isPrecise
in classDurationField
- Returns:
- true if precise
- See Also:
DurationField.getUnitMillis()
-
getUnitMillis
public long getUnitMillis()
Description copied from class:DurationField
Returns the amount of milliseconds per unit value of this field. For example, if this field represents "seconds", then this returns the milliseconds in one second.For imprecise fields, the unit size is variable, and so this method returns a suitable average value.
- Specified by:
getUnitMillis
in classDurationField
- Returns:
- the unit size of this field, in milliseconds
- See Also:
DurationField.isPrecise()
-
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".
- Specified by:
getValueAsLong
in 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, 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".
- Specified by:
getMillis
in 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: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".
- Specified by:
getMillis
in 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:DurationField
Adds a duration value (which may be negative) to the instant.- Specified by:
add
in 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:DurationField
Adds a duration value (which may be negative) to the instant.- Specified by:
add
in 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: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'.- Specified by:
getDifferenceAsLong
in 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
