public interface DateTimeMapFunctions extends TemporalMapFunctions<LocalDateTime>
| Modifier and Type | Method and Description |
|---|---|
default DateColumn |
date()
Returns a DateColumn containing the date portion of each dateTime in this DateTimeColumn
|
default IntColumn |
dayOfMonth() |
default StringColumn |
dayOfWeek() |
default IntColumn |
dayOfWeekValue() |
default IntColumn |
dayOfYear() |
default IntColumn |
hour() |
default StringColumn |
hourMinute()
Returns a StringColumn with the year and week-of-year derived from this column concatenated into a String
that will sort lexicographically in temporal order.
|
DateTimeColumn |
lag(int n)
Returns a column of the same type and size as the receiver, containing the receivers values offset by n.
|
default DateTimeColumn |
lead(int n)
Returns a column of the same type as the receiver, containing the receivers values offset -n
For example if you lead a column containing 2, 3, 4 by 1, you get a column containing 3, 4, NA.

minute() |
default IntColumn |
minuteOfDay() |
default StringColumn |
month()
Returns a StringColumn containing the name of the month for each date/time in this column

default IntColumn |
secondOfDay() |
default TimeColumn |
time()
Returns a TimeColumn containing the time portion of each dateTime in this DateTimeColumn
|
default LongColumn |
timeWindow(ChronoUnit unit,
int n) |
default LongColumn |
timeWindow(ChronoUnit unit,
int n,
LocalDateTime start)
Returns a column containing integers representing the nth group (0-based) that a date falls into.
|
default IntColumn |
year() |
default StringColumn |
yearDay()
Returns a StringColumn with the year and day-of-year derived from this column concatenated into a String
that will sort lexicographically in temporal order.
|
default StringColumn |
yearMonth()
Returns a StringColumn with the year and month from this column concatenated into a String that will sort
lexicographically in temporal order.
|
default StringColumn |
yearQuarter()
Returns a StringColumn with the year and quarter from this column concatenated into a String that will sort
lexicographically in temporal order.
|
default StringColumn |
yearWeek()

This simplifies the production of plots and tables that aggregate values into standard temporal units (e.g., you want monthly data but your source data is more than a year long and you don't want months from different years aggregated together).
default StringColumn yearMonth()
This simplifies the production of plots and tables that aggregate values into standard temporal units (e.g., you want monthly data but your source data is more than a year long and you don't want months from different years aggregated together).
default StringColumn yearDay()
This simplifies the production of plots and tables that aggregate values into standard temporal units (e.g., you want monthly data but your source data is more than a year long and you don't want months from different years aggregated together).
