C	emptyCopy()	Returns a copy of the receiver with no data.
C	lag(int n)	Returns a column of the same type and size as the receiver, containing the receivers values offset by n.
default C	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.

Method Details

min

T min()

emptyCopy

C emptyCopy()

Description copied from interface: Column

Returns a copy of the receiver with no data. The column name and type are the same.

Specified by:

emptyCopy in interface Column<C extends TemporalColumn<T>>

Returns:

a empty copy of Column

lag

C 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<C extends TemporalColumn<T>>

lead

default C 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<C extends TemporalColumn<T>>
