public interface HeaderRow<T,C extends Column<? extends T>>
extends ColumnRow<T,C>, List<C>

A list of Column instances, for example describing the elements of a CSV file (visually speaking the of the CSV file's header line), is represented by the HeaderRow. The HeaderRow preserves an order for a list of Column instances. A HeaderRow provides the semantics for related Row instances.

The Keys.keySet() method must provide a predictable order as ensured by the LinkedHashSet class as of the ordered nature of the HeaderRow.

ColumnMismatchException - Thrown in case a value was found in the e.g. in a Record of the wrong type than specified by a Column of the HeaderRow.

toPrintableRow

Row<String> toPrintableRow(Record<? extends T> aRecord)
                    throws HeaderMismatchException,
ColumnMismatchException

A https://www.metacodes.pro Column implementation might provide its own printable format of the given objects; for example a human readable text representation of the value (or in very https://www.metacodes.proized cases even enriched with ANSI Escape-Codes). This method enables the HeaderRow to convert a value of the given type to a human readable text. The human readable text, in comparison to the method toRow(Record) (or toStorageStringsRecord(Row) is not intended to be converted back to the actual value (not bijective). This method may use a Column instance's method Column.toPrintable(Object); it also might enrich the output of the Column.toPrintable(Object) with device specific additional data such as ANSI Escape-Codes and with information regarding the Record as a whole and not just be regarding a single value.

Parameters:

aRecord - the Record to be converted to a human readable text Row.

Returns:

The human readable Row representation of the Record.

Throws:

HeaderMismatchException - Thrown in case there is a mismatch between the given HeaderMismatchException and the Row, i.e. the index for the given key in the header may be out of index of the given row or the given key does not exist in the HeaderRow.

ColumnMismatchException - Thrown in case a value was found in the e.g. in a Record of the wrong type than specified by a Column of the HeaderRow.
