railo.commons.lang.ParserString
Der CFMLString ist eine Hilfe fuer die Transformer, er repraesentiert den CFML Code und bietet Methoden an, um alle noetigen Informationen auszulesen und Manipulationen durchzufuehren. Dies um, innerhalb des Transformer, wiederkehrende Zeichenketten-Manipulationen zu abstrahieren.
