All Implemented Interfaces:
Enumeration<Object>
public class QuotedStringTokenizer extends 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 double quoted string values are recognised. Delimiters within quotes are not considered delimiters. Quotes can be escaped with '\'.
