Package org.refcodes.tabular

Interface Columns<T>

Type Parameters:

T - The type managed by the Columns.

All Superinterfaces:

org.refcodes.structure.Clearable, Collection<T>, ColumnsTemplate<T,Column<? extends T>>, Iterable<T>, org.refcodes.structure.Keys<T,C>, org.refcodes.structure.Keys.MutableKeys<String,C>

public interface Columns<T>
extends ColumnsTemplate<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.
