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 doulbe quoted string values are recognized. Delimiters within quotes are not considered delimiters. Quotes can be escaped with '\'.

Constructor Detail

QuotedStringTokenizer

public QuotedStringTokenizer(String str,
                             String delim,
                             boolean returnDelimiters,
                             boolean returnQuotes)

Parameters:

str - String to tokenize.

delim - List of delimiter characters as string. Can be null, to default to ' \t\n\r'

returnDelimiters - If true, nextToken() will include the delimiters, not just tokenized tokens.

returnQuotes - If true, nextToken() will include the quotation characters when they are present.
