Overview

– Abgeleitet von Source behandelt die Klasse Dateien mit dem Format MultiKey. Eine Zeile "Triumph;Sieg;Erfolg\n" wird gewandelt in [ 'triumph', ['sieg', 'erfolg'] ]. Die Sonderbehandlung erfolgt in der Methode Database#convert, wo daraus Schlüssel-Werte-Paare in der Form [ 'sieg', ['triumph'] ] und [ 'erfolg', ['triumph'] ] erzeugt werden. Der Trenner zwischen Schlüssel und Projektion kann über den Parameter separator geändert werden. ++
