http://issues.apache.org/bugzilla/show_bug.cgi?id=35037 ------- Additional Comments From [EMAIL PROTECTED] 2005-05-25 01:08 ------- The area of code that is affected by this is in DocumentWriter.invertDocument(Document): ... Reader reader; // find or make Reader if (field.readerValue() != null) reader = field.readerValue(); else if (field.stringValue() != null) reader = new StringReader(field.stringValue()); else throw new IllegalArgumentException ("field must have either String or Reader value"); In my test scenario I do not use a reader, all my Fields are created as normal String values, so the first if() to determine if the reader comes back null will always result in an ClassCastException. That's 1 ClassCastException for each Indexed & Tokenized field _per_ Document. I'm not sure of whether String/Reader is more prevelant out there in the wild, but I would have thought String would have been common. Sure for large documents like PDF's etc it's more likely a Reader will be used. Anyway, for the try/catch block, the JVM performs an implicit ClassCast check anyway, that's how it determines whether it should throw an exception or not, so there is no way to avoid some form of an instanceof. Modern JVM's are quicker with instanceof. However this may not (probably not) true for older (1.2 or earlier?) VM's, although I don't have access to that anymore test that theory. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
