There is a drawback to interfaces too... you can't easily add an extra method in a back-compatible way like you can with classes by providing a default implementation. For example, this enabled adding getPositionIncrement() to Tokenizer, and adding hasNorms() to IndexReader without breaking any subclasses. -Yonik http://incubator.apache.org/solr Solr, the open-source Lucene search server --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
