Markupstream.hasMore vs. MarkupStream.next
Hi all,
hasMore: return currentIndex < markup.size();
next: if (++currentIndex < markup.size()) {...}
me: while (markupStream.hasMore()) {...}
I get a null element within the while loop which I wouldn't expect to
get. markup.size() is 73, currentIndex 72, so hasMore returns true,
while next returns null, because it already advanced the index on its
check.
Is this a bug or is using hasMore the wrong idiom in this case?
I just followed code in the core codebase, like in Enclosure, the only
difference there is that the result of next is ignored. Of course I
can check for null and such, I just didn't expect such a behavior.
Mit freundlichen Grüßen,
Thorsten Schöning
