Csv

case class Csv(header: Row, dataRows: Iterator[Row], validations: Seq[(Row) ⇒ (Row) ⇒ Row] = Csv.defaultValidations) extends Iterable[Row] with Product with Serializable

Csv encapsulates a tabular data structure, as found in a CSV file or spreadsheet. This class is a thin wrapper around an Iterator[Row] and a header Row. It allows client code to:

This class may be useful for:

Csv is designed to be lazy. All materialisation of the datasource is done OUTSIDE of the Csv, i.e. as late as possible. Thus, there should be no appreciable time cost to constructing a Csv, merging Csvs, restructuring columns, and so forth. The time cost is only paid once, when the client code exports or otherwise materialises the Csv.

TODO - CAS - 07/08/2014 - A Y-shaped pipeline (spits out two CSVs) TODO - CAS - 07/08/2014 - Aggregator 1 - merge columns (e.g. (firstName, surname) -> s"$firstName $surname") TODO - CAS - 07/08/2014 - Aggregator 2 - merge rows - provide a predicate for row grouping/inclusion/exclusion
