def partsAcceptor(reqInfo: HReqHeaderData): Option[HPartsAcceptor]

When this HLet accepts multipart requests, this method must return a parts acceptor that will process the different parts.

class ImageUpload extends HSimpleLet {

  class ImagePartsAcceptor(reqInfo: HReqHeaderData)
       extends HPartsAcceptor(reqInfo) {

    // the parts are stored in a byte array output stream
    private var input: ByteArrayOutputStream = _

    // accept only uploaded image files
    def open(desc: HPartDescriptor) =
      reqInfo.header("Content-Type") match {
        case Some(mime) if mime.startsWith("image/") =>
          input = new ByteArrayOutputStream
          true
        case _ => false
      }

    def accept(bytes: Array[Byte]) = {
      // write part into the buffer
      input.write(bytes)
      // accept more parts
      true
    }

    def close {
      // save the bytes containing the image
      image = Some(input.toByteArray)
      // close the output stream
      input.close
      input = null
    }

    def declineAll { input = null }
 }

private var image: Option[Array[Byte]] = None

def act(talk: HTalk) = {
  val response = image match {
    case Some(img) => "Image uploaded"
    case None => "Not uploaded Image"
  }

  talk.setContentLength(response.length).write(response)

}
