Abstract Value Members

  1. abstract def aact(talk: HTalk): Future[Any]

    This method contains the actual (suspendable) computation.

    This method contains the actual (suspendable) computation. The given talk parameter contains the methods to access the request and session data, as well as the method to send the response to the client. This method is called asynchronously (hence the name aact)

  18. 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.

    When this HLet accepts multipart requests, this method must return a parts acceptor that will process the different parts. An example of part acceptor is:

    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)

  }
