Class org.paneris.util.CSVStringTokenizer 

java.lang.Object
   |
   +----org.paneris.util.CSVStringTokenizer
public class CSVStringTokenizer
extends Object
implements Enumeration
This is a complete butchery of java.util.StringTokenizer, it needs sorting out, but appears to process lines in a .csv file correctly.

Constructor Index

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

Constructors

o CSVStringTokenizer 
 public CSVStringTokenizer(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 CSVStringTokenizer 
 public CSVStringTokenizer(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 CSVStringTokenizer 
 public CSVStringTokenizer(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
