<P>
The MultipartIterator class is responsible for reading the input data of a multipart request and splitting it up into input elements, wrapped inside of a <A HREF="../../../../org/apache/struts/upload/MultipartElement.html"><CODE>MultipartElement</CODE></A> for easy definition. To use this class, create a new instance of MultipartIterator passing it a HttpServletRequest in the constructor. Then use the <A HREF="../../../../org/apache/struts/upload/MultipartIterator.html#getNextElement()"><CODE>getNextElement</CODE></A> method until it returns null, then you're finished. Example: <br> <pre> MultipartIterator iterator = new MultipartIterator(request); MultipartElement element; while ((element = iterator.getNextElement()) != null) { //do something with element } </pre>
