Re: StringTokenizer

Thanks Gary.  After searching through API list, I decide to write one.
Kindly, you already wrote one for me.  Thanks again.

Subject:  Re: StringTokenizer


I don't know of such a class but I just hacked this one together:

class ExpStringTokenizer extends java.util.StringTokenizer {

  private boolean m_expectingDelimiter = false;
  private String m_delims;

  public ExpStringTokenizer(String str) {
    this(str, " \t\n\r\f");
  }

  public ExpStringTokenizer(String str, String delim) {
    super(str, delim, true);
    m_delims = delim;
  }

  public String nextToken() {

    while (true)
    {
      String next = super.nextToken();
      if (m_expectingDelimiter)
        m_expectingDelimiter = false;
      else
      {
        boolean isDelimiter = (m_delims.indexOf(next) >= 0);
        if (isDelimiter)
          return null;
        else
        {
          m_expectingDelimiter = true;
          return next;
        }
      }
    }
  }
}

Seems like putting the rest of the methods in shouldn't be too hard.
