RawRowProjection

com.phasmidsoftware.tableparser.core.table.RawRowProjection
case class RawRowProjection(columns: Seq[Int]) extends Transformation[RawRow, RawRow]

A case class RawRowProjection that transforms a RawRow into another RawRow by selecting specific columns.

This transformation operates based on the specified indices of the columns to be kept. It selects the raw string values (ws) of the input RawRow corresponding to the provided indices and produces a new RawRow with the filtered data, while retaining the header from the input.

Value parameters

columns

A sequence of integers representing column indices to retain in the transformation.

Concrete methods

def apply(r: RawRow): RawRow

Transforms a given RawRow into a new RawRow by selectively retaining columns based on the indices specified in the columns parameter of the enclosing RawRowProjection class.

Transforms a given RawRow into a new RawRow by selectively retaining columns based on the indices specified in the columns parameter of the enclosing RawRowProjection class.

For each value in the input row (r), if its corresponding column index exists in the columns sequence, it is included in the resulting RawRow. The header of the resulting RawRow remains unchanged.

Value parameters

r

the input RawRow containing a sequence of strings (ws) and a header (header).

Attributes

Returns

a new RawRow that contains only the filtered values as per the specified column indices and retains the original header from the input row.

Inherited methods

def andThen[A](g: RawRow => A): RawRow => A

Value parameters

g

a function R => A

Returns

a new function f such that f(x) == g(apply(x))

def compose[A](g: A => RawRow): A => RawRow

Composes two instances of Function1 in a new Function1, with this function applied last.

Composes two instances of Function1 in a new Function1, with this function applied last.

Type parameters

A

the type to which function g can be applied

Value parameters

g

a function A => T1

Attributes

Returns
