I'm not sure I see your problem. The parse() method either returns or
throws an exception. If it returns normally, the end of document was
seen. If it throws an exception it wasn't.
Of course the filter only really nows what the previous filter in the
chain tells it. It doesn't know and doesn't need to know what filters
earlier in the chain say. That's the point of filtering.
