java.lang.Object

   +----cynosurex.util.EnhancedStringTokenizer

public class EnhancedStringTokenizer
extends Object
implements Enumeration
EnhancedStringTokenizer is an enhancement of the Java StringTokenizer class. It added the ability to peek at the next token, to return the last token, and to reset the queue.

Constructor Index

 o EnhancedStringTokenizer(String)
Constructs a string tokenizer for the specified string.
 o EnhancedStringTokenizer(String, String)
Constructs a string tokenizer for the specified string.
 o EnhancedStringTokenizer(String, String, boolean)
Constructs a string tokenizer for the specified string.
 o EnhancedStringTokenizer(String, String, boolean, boolean)

Constructs a string tokenizer for the specified string.

Method Index

 o countTokens()
Calculates the number of times that this tokenizer's nextToken method can be called before it generates an exception.
 o hasMoreElements()
Returns the same value as the hasMoreTokens method.
 o hasMoreTokens()
Tests if there are more tokens available from this tokenizer's string.
 o lastToken()
Method to return the last token in the queue.
 o nextElement()
Returns the same value as the nextToken method, except that its declared return value is Object rather than String.
 o nextToken()
Returns the next token from this string tokenizer.
 o nextToken(String)
Returns the next token in this string tokenizer's string.
 o peekToken()
Method to return the next token without removing it from the queue.
 o reset()
Method to return the StringTokenizer to the original queue.

Constructors

 o EnhancedStringTokenizer
  public EnhancedStringTokenizer(String str,
                                 String delim,
                                 boolean returnTokens,
                                 boolean multiDelim)

Constructs a string tokenizer for the specified string. The characters in the delim argument are the delimiters for separating tokens.

If the returnTokens flag is true, then the delimiter characters are also returned as tokens. If the flag is false, the delimiter characters are skipped and only serve as separators between tokens.

If the multiDelim flag is true, then multiple delimiters are returned as one token. If false, each delimiter is returned as a string of length one. This flag has no effect if delimiters are not returned as tokens.

Parameters:
str - a string to be parsed.
delim - the delimiters.
returnTokens - flag indicating whether to return the delimiters as tokens.
multiDelim - flag indicating whether to return multiple delimiters as one token.
 o EnhancedStringTokenizer
  public EnhancedStringTokenizer(String str,
                                 String delim,
                                 boolean returnTokens)
Constructs a string tokenizer for the specified string. The characters in the delim argument are the delimiters for separating tokens.

If the returnTokens flag is true, then the delimiter characters are also returned as tokens. Each delimiter is returned as a string of length one. If the flag is false, the delimiter characters are skipped and only serve as separators between tokens.

Parameters:
str - a string to be parsed.
delim - the delimiters.
returnTokens - flag indicating whether to return the delimiters as tokens.
 o EnhancedStringTokenizer
  public EnhancedStringTokenizer(String str,
                                 String delim)
Constructs a string tokenizer for the specified string. The characters in the delim argument are the delimiters for separating tokens.
Parameters:
str - a string to be parsed.
delim - the delimiters.
 o EnhancedStringTokenizer
  public EnhancedStringTokenizer(String str)
Constructs a string tokenizer for the specified string. The tokenizer uses the default delimiter set, which is "\t\n\r": the space character, the tab character, the newline character, and the carriage-return character.
Parameters:
str - a string to be parsed.

Methods

 o hasMoreTokens
  public boolean hasMoreTokens()
Tests if there are more tokens available from this tokenizer's string.
Returns:
true if there are more tokens available from this tokenizer's string; false otherwise.
 o nextToken
  public String nextToken()
Returns the next token from this string tokenizer.
Returns:
the next token from this string tokenizer.
Throws: NoSuchElementException
if there are no more tokens in this tokenizer's string.
 o nextToken
  public String nextToken(String delim)
Returns the next token in this string tokenizer's string. The new delimiter set remains the default after this call.
Parameters:
delim - the new delimiters.
Returns:
the next token, after switching to the new delimiter set.
Throws: NoSuchElementException
if there are no more tokens in this tokenizer's string.
 o hasMoreElements
  public boolean hasMoreElements()
Returns the same value as the hasMoreTokens method. It exists so that this class can implement the Enumeration interface.
Returns:
true if there are more tokens; false otherwise.
See Also:
Enumeration, hasMoreTokens
 o nextElement
  public Object nextElement()
Returns the same value as the nextToken method, except that its declared return value is Object rather than String. It exists so that this class can implement the Enumeration interface.
Returns:
the next token in the string.
Throws: NoSuchElementException
if there are no more tokens in this tokenizer's string.
See Also:
Enumeration, nextToken
 o countTokens
  public int countTokens()
Calculates the number of times that this tokenizer's nextToken method can be called before it generates an exception.
Returns:
the number of tokens remaining in the string using the current delimiter set.
See Also:
nextToken
 o peekToken
  public String peekToken()
Method to return the next token without removing it from the queue.
 o lastToken
  public String lastToken()
Method to return the last token in the queue.
 o reset
  public void reset()
Method to return the StringTokenizer to the original queue.
