hi there arjan
<arjanb>hi14:16
<fcb>Nice isn't compiling again :(14:20
<arjanb>what nicec version do you have?14:21
<fcb>i got latest nice.jar today: Nice compiler version 0.9.8 (build 2004.07.02, 18:42:24 UTC)14:22
<arjanb>that on might be to old14:24
<fcb>oh? when was the latest one done?14:25
<arjanb>hmm that version is working for me14:27

that's the lot
you use a batch file, though, so if you want me to take it up with Daniel instead that's fine14:43
<arjanb>i don't use the makefile myself but daniel is away this week so i will try to find out14:44
<fcb>oh, ok
thanks
do you have something under src/nice/tools/locator? locator isn't on my system14:45
<arjanb>do you have the latest cvs version?
<fcb>yes, I did a "cvs update" just now14:47
<arjanb>you should have locator now
does it work now?14:50
<fcb>I just did a cvs update, and it didn't download locator14:51
so its still not working
<arjanb>maybe something with file permissions for cvs?
<fcb>do I need to actually perform a new checkout?14:52
<arjanb>update should work but you could try a checkout14:53
<fcb>I ran "cvs checkout Nice/src/nice/tools/locator" and its working now!14:54
pheeew :)14:55
<arjanb>:-)
strange that update didn't work
<fcb>yeah. never mind14:56

ok, do you have time to help me a little more?
<arjanb>yes15:03
<fcb>excellent :) I want to extend StringTokenizer, but I get this error: No method called hasMoreElements is compatible with these patterns15:04
the method in question is very simple:15:05
hasMoreElements() {
return hasMoreTokens();
}
as far as I can see, hasMoreElements is perfectly compatible with this.15:11
<arjanb>i guess it has something to do with type param of Enumeration that is a super class of StringTokenizer15:13
that code isn't usefull because hasMoreElements and hasMoreTokens() does the same in StringTokenizer15:14
<fcb>but I want to override the hasMoreTokens method, and I want to make sure that hasMoreElements and hasMoreTokens do the same thing.15:15
* CIA-5 leaves15:16

<fcb>I couldn't be bothered looking at the source code for StringTokenizer to see which method calls which, so I thought this was safer.
Nice doesn't seem to realise that StringTokenizer has a method called hasMoreElements()15:23
is this a compiler bug?
<arjanb>the problem is hasMoreElement() is defined in Enumeration15:24
<fcb>but StringTokenizer still implements it15:25
<arjanb>Enumeration has 1 type param and the sub class StringTokenizer zero and the type system has difficulties with different number of types params
<fcb>I thought both had zero params15:27
<arjanb>even the debugging options don't give more info on what's wrong :(15:29
<fcb>hmm, damn
<arjanb>does it work if you just leave hasMoreElements away?15:30
<fcb>yes, I get problems with other methods then :)15:32
<arjanb>try putting the methods outside the class like:15:35
class STSub extends StringTokenizer {}
hasMoreTokens(STSub this) {
return true;
}
<fcb>still thinks my patterns are incompatible15:37
<arjanb>only hasMoreElements?15:38
<fcb>and nextElement()15:40
<arjanb>nextElement() is part of Enumeration too15:41
<fcb>yes, exactly
don't worry about it15:42
I have greater problems
anyway, thanks for all your help15:44
my eyes are tired now - goodnight
<arjanb>good night
