Class UploadParser

java.lang.Object

to.etc.domui.util.upload.UploadParser

public class UploadParser
extends Object

This is a file upload parser which parses input type=file requests as posted from forms. It expects an input stream encoded as described in RFC 1867. The input stream is split into it's constituent parts and returned as a parameter map.

This code replaces the apache fileupload code because that code does not properly return the fact that *no* file was uploaded (i.e. the input was empty), and because that implementation does not return an actual File without casting.

To use this, first ask if a HttpRequest is a valid upload request using the "isMultipartContent()" call. Then ask an instance of this class to parse the request. This returns a Map of items present in the request.
