Declaration

public class PHXStringTokenizer
extends java.lang.Object
implements java.util.Enumeration

This is a more sophisticated version of the Java StringTokenizer. Using the StringTokenizer source as a starting point, the source code was modified to recognize quoted strings as separate tokens.

The following is one example of the use of the tokenizer. The code:

PHXStringTokenizer st = new PHXStringTokenizer( "this \"is a\" test" );
while ( st.hasMoreTokens() )
{
   System.out.println( st.nextToken() );
}

prints the following output:


This
is a
test

The "doUnslash" option is true by default and makes it unslash special backslash sequences correctly (like a unix shell prompt does). It can be set to false for backwards compatibility but is recommended strongly that we use true as much as possible.

Constructor Detail

PHXStringTokenizer

public PHXStringTokenizer(java.lang.String str, 
                          java.lang.String delim)

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 1. 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.

Throws:

  • java.lang.IllegalArgumentException - thrown if " is specified as a delimiter

PHXStringTokenizer

public PHXStringTokenizer(java.lang.String str,

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 1. 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.
  • doUnslash - Whether to unslash slashed characters (\n)

Throws:

  • java.lang.IllegalArgumentException - thrown if " is specified as a delimiter
