findNext vs. findFirst

In MolPrinter I don't understand why a findFirst method is needed and what it does: why would you make a distinction between the first vs. the other matches? Does that mean that

Code:

int[] hits;    while ((hits = s.findNext()) != null)          doStuff(hits)

somehow will not work?

Yes, it would work, findNext() does the search initialization if needed.





The difference is that findFirst() always re-initializes the search. (So if you want to re-start the enumeration of the hits, you need to use findFirst() instead of findNext().)

OK. A restartable iterator is neat indeed. That should be added to the findFirst javadocs.

OK, I made it explicit in the javadocs for the next releases.





Thanks!
