Examples of java.io.ByteArrayInputStream.reset()

java.io.ByteArrayInputStream.reset()
Reset this ByteArrayInputStream to the last marked location. This implementation resets the position to either the marked position, the start position supplied in the constructor or 0 if neither is provided.

    try {
      WordExtractor docextractor = new WordExtractor(is);
      ret = docextractor.getText();
    } catch (OldWordFileFormatException e) {
      try {
        is.reset();
        Word6Extractor docextractor = new Word6Extractor(is);
        ret = docextractor.getText();
      } catch (IOException e1) {
        throw new CRException(e1);
