Package org.refcodes.tabular

Interface Columns<T>

  • Type Parameters:
    T - The type managed by the Columns.
    All Superinterfaces:
    org.refcodes.structure.Clearable, java.util.Collection<T>, ColumnRow<T,Column<? extends T>>, java.lang.Iterable<T>, org.refcodes.structure.Keys<T,C>, org.refcodes.structure.Keys.MutableKeys<java.lang.String,C>

    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.
