Interface Columns<T>

Type Parameters:
T - The type managed by the Columns.
All Superinterfaces:
Clearable, Collection<Column<? extends T>>, ColumnRow<T, Column<? extends T>>, Iterable<Column<? extends T>>, Keys<String, Column<? extends T>>, Keys.MutableKeys<String, Column<? extends T>>
public interface Columns<T> extends ColumnRow<T, Column<? extends T>>
In case no order of the Column instances is explicitly required (similar to a DB table or a spread sheet, in contrast to a CSV file) then Column instances are grouped by a Columns set.

Columns provide additional semantics to the Field instances stored in a Record.
