public class QuotedStringTokenizer
extends java.util.StringTokenizer

StringTokenizer with Quoting support. This class is a copy of the java.util.StringTokenizer API and the behaviour is the same, except that single and doulbe quoted string values are recognized. Delimiters within quotes are not considered delimiters. Quotes can be escaped with '\'.
