[Biojava-l] RichSequenceIterator.hasNext from empty file return true!!!

[Khalil El Mazouari]

Hi,

RichSequenceIterator.hasNext from empty file return true!!! and throws an infinite BioException loop!!!
Any explanation?? Thanks

khalil

test using the following code

    public static void main(String[] args) {
       String path = "emptyFile.txt";

         BufferedReader br = null;
      try {
         br = new BufferedReader(new FileReader(path));
      } catch (FileNotFoundException ex) {
         ex.printStackTrace();
      }
      RichSequenceIterator seqs = RichSequence.IOTools.readFastaProtein(br, null);
        while (seqs.hasNext()) {
         try {
            RichSequence seq = seqs.nextRichSequence();
         } catch (NoSuchElementException ex) {
            ex.printStackTrace();
         } catch (BioException ex) {
            ex.printStackTrace();
         }
        }
