Subject CharRange UNSET ?
Date Fri, 27 Sep 2002 22:28:32 GMT
CharRange uses an unassigned static character, UNSET, as a flag value
for testing if the range is a range or a single value.

This looks a little odd to me. I had the distinct impression that
accessing an unassigned value was an error. However, the comparison
works. I'm just not sure it's working as intended, and won't fail to
work an a different VM?

relevant code:
     * Used internally to represent null in a char.
    private static char UNSET;

// ...

     * Is this CharRange over many characters
     * @return boolean true is many characters
    public boolean isRange() {
        return this.close != UNSET;
