Method Detail

dateColumnName

static String dateColumnName(Column column1,
                             int value,
                             TemporalUnit unit)

differenceInDays

default FloatColumn differenceInDays(DateColumn column2)

differenceInWeeks

default FloatColumn differenceInWeeks(DateColumn column2)

differenceInMonths

default FloatColumn differenceInMonths(DateColumn column2)

differenceInYears

default FloatColumn differenceInYears(DateColumn column2)

difference

default FloatColumn difference(DateColumn column1,
                               DateColumn column2,
                               ChronoUnit unit)

Calculates the temporal difference between each element of the receiver and the respective element of the argument

Missing values in either result in a Missing Value for the new column

minusDays

default DateColumn minusDays(int days)

minusWeeks

default DateColumn minusWeeks(int weeks)

minusYears

default DateColumn minusYears(int years)

minusMonths

default DateColumn minusMonths(int months)

plus

                        TemporalUnit unit)

minus

default DateColumn minus(int value,
                         TemporalUnit unit)

atStartOfDay

atTime

default DateTimeColumn atTime(LocalTime time)

Returns a DateTime column where each value consists of the dates from this column combined with the corresponding times from the other column

atTime

default DateTimeColumn atTime(TimeColumn timeColumn)

Returns a DateTime column where each value consists of the dates from this column combined with the corresponding times from the other column
