Hello Philip, Thursday, February 26, 2004, 10:05:09 PM, you wrote: > Hi Marcus > Yes, the current implementation of hasMore() has an identical semantic to > isValid(). > The generally understood semantic of isValid() and hasMore() are quite > different - hence the need for the rename. As a side note: There is no generally understood hasMore(). Though there is isDone() and hasMore() is sometimes used/implemented as !isDone(). The main problem is that the original Iterator description everyone refers to doesn't have isValid() but instead only has isDone() which doesn't fit into for(;;).
