Method Detail

differenceInMilliseconds

default IntColumn differenceInMilliseconds(TimeColumn column2)

differenceInSeconds

default IntColumn differenceInSeconds(TimeColumn column2)

differenceInMinutes

default IntColumn differenceInMinutes(TimeColumn column2)

differenceInHours

default IntColumn differenceInHours(TimeColumn column2)

lead

default TimeColumn lead(int n)

Description copied from interface: Column

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.

Specified by:

lead in interface Column<LocalTime>

lag

TimeColumn lag(int n)

Description copied from interface: Column

Returns a column of the same type and size as the receiver, containing the receivers values offset by n.

For example if you lag a column containing 2, 3, 4 by 1, you get a column containing NA, 2, 3

Specified by:

lag in interface Column<LocalTime>

difference

default IntColumn difference(TimeColumn column2,
                             ChronoUnit unit)

plus

default TimeColumn plus(int time,
                        ChronoUnit unit)

minus

default TimeColumn minus(int time,
                         ChronoUnit unit)

with

default TimeColumn with(int time,
                        ChronoUnit unit)

withHour

default TimeColumn withHour(int hours)

plusHours

default TimeColumn plusHours(int hours)

withMinute

default TimeColumn withMinute(int minutes)

plusMinutes

default TimeColumn plusMinutes(int minutes)

withSecond

default TimeColumn withSecond(int seconds)

plusSeconds

default TimeColumn plusSeconds(int seconds)

withMillisecond

default TimeColumn withMillisecond(int millis)

plusMilliseconds

default TimeColumn plusMilliseconds(int millis)

minusHours

default TimeColumn minusHours(int hours)

minusMinutes

default TimeColumn minusMinutes(int minutes)

minusSeconds

default TimeColumn minusSeconds(int seconds)

minusMilliseconds

default TimeColumn minusMilliseconds(int millis)

default TimeColumn truncatedTo(ChronoUnit unit)

hour

default IntColumn hour()

minute

default IntColumn minute()

second

default IntColumn second()

default IntColumn minuteOfDay()

secondOfDay

default IntColumn secondOfDay()

timeWindow

default DoubleColumn timeWindow(ChronoUnit unit,
                                int n,
                                LocalTime start)

Returns a column containing integers representing the nth group (0-based) that a date falls into.

Example: When Unit = ChronoUnit.DAY and n = 5, we form 5 day groups. a Date that is 2 days after the start is assigned to the first ("0") group. A day 7 days after the start is assigned to the second ("1") group.

Parameters:

unit - A ChronoUnit greater than or equal to a day

n - The number of units in each group.

start - The starting point of the first group; group boundaries are offsets from this point

hourMinute

default StringColumn hourMinute()

Returns a StringColumn with the hour and minute-of-hour derived from this column concatenated into a String that will sort lexicographically in temporal order.

This simplifies the production of plots and tables that aggregate values into standard temporal units

timeWindow

default DoubleColumn timeWindow(ChronoUnit unit,
                                int n)

get

LocalTime get(int r)

Description copied from interface: Column

Returns the value at the given zero-based index

Specified by:

get in interface Column<LocalTime>

getIntInternal

int getIntInternal(int r)

min

LocalTime min()
