Method Detail

differenceInMilliseconds

default NumberColumn differenceInMilliseconds(TimeColumn column2)

differenceInSeconds

default NumberColumn differenceInSeconds(TimeColumn column2)

differenceInMinutes

default NumberColumn differenceInMinutes(TimeColumn column2)

differenceInHours

default NumberColumn 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

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

difference

                        ChronoUnit unit)

minus

default TimeColumn minus(int time,
                         ChronoUnit unit)

with

default TimeColumn with(int time,
                        ChronoUnit unit)

difference

default long difference(int packedLocalTime1,
                        int packedLocalTime2,
                        ChronoUnit unit)

withHour

timeWindow

default NumberColumn 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 NumberColumn timeWindow(ChronoUnit unit,
                                int n)

get

LocalTime get(int r)

getIntInternal

int getIntInternal(int r)

min

LocalTime min()
