Class MyStringTokenizer

  +--org.xbill.DNS.utils.MyStringTokenizer

public class MyStringTokenizer

extends Object

implements Enumeration

A class similar to StringTokenizer, with a few differences making it more suitable. The \ character is used as an escape character, allowing delimiters to be escaped and \xxx decimal value to be used. Quoted strings (delimited by double quotes) are treated as one token.

Constructor Summary

MyStringTokenizer(String _s)
Creates a new instance of MyStringTokenizer, with whitespace delimiters (space, tab, newline).

MyStringTokenizer(String _s, String _delim)
Creates a new instance of MyStringTokenizer.

MyStringTokenizer(String _s, String _delim, boolean _returnTokens)
Creates a new instance of MyStringTokenizer.

Method Summary

boolean	hasMoreDelimiters() Are there any more delimiters in the string? This should only be called if hasMoreTokens is false, to determine if the string contains trailing delimiters.
boolean	hasMoreElements() Are there any more tokens in the string
boolean	hasMoreTokens() Are there any more tokens in the string
static void	main(String[] args)
Object	nextElement() Returns the next token
String	nextToken() Returns the next token
void	putBackToken(String s) Specifies a string to be added to the MyStringTokenizer object.
String	remainingTokens() Returns a concatenation of all remaining tokens
void	setNoEscapeCharacter() Turns off the escape character.

Constructor Detail

MyStringTokenizer

public MyStringTokenizer(String _s,
                         String _delim,
                         boolean _returnTokens)

Creates a new instance of MyStringTokenizer.

Parameters:

s - The string to be tokenized

delim - A string containing all delimiters

returnTokens - If true, return delimiters as tokens. This differs from StringTokenizer in that adjacent delimiters are returned in the same token.

MyStringTokenizer

public MyStringTokenizer(String _s,
                         String _delim)

Creates a new instance of MyStringTokenizer.

Parameters:

s - The string to be tokenized

delim - A string containing all delimiters

MyStringTokenizer

public MyStringTokenizer(String _s)

Creates a new instance of MyStringTokenizer, with whitespace delimiters (space, tab, newline).

Parameters:

s - The string to be tokenized

Method Detail

setNoEscapeCharacter

public void setNoEscapeCharacter()

Turns off the escape character. Useful when tokenizing the output of the tokenizer.

hasMoreTokens

public boolean hasMoreTokens()

Are there any more tokens in the string

hasMoreElements

public boolean hasMoreElements()

Are there any more tokens in the string

Specified by:

hasMoreElements in interface Enumeration

hasMoreDelimiters

public boolean hasMoreDelimiters()

Are there any more delimiters in the string? This should only be called if hasMoreTokens is false, to determine if the string contains trailing delimiters.

nextToken

public String nextToken()

Returns the next token

nextElement

public Object nextElement()

Returns the next token

Specified by:

nextElement in interface Enumeration

putBackToken

public void putBackToken(String s)

Specifies a string to be added to the MyStringTokenizer object. The next call to nextToken() will return this string.

remainingTokens

public String remainingTokens()

Returns a concatenation of all remaining tokens

main

public static void main(String[] args)
                 throws IOException
