## Class IncomingDatagramMessage<O extends UpnpOperation>

- java.lang.Object
- - org.fourthline.cling.model.message.UpnpMessage<O>
  - - org.fourthline.cling.model.message.IncomingDatagramMessage<O>

- Direct Known Subclasses:
    IncomingNotificationRequest, IncomingSearchRequest, IncomingSearchResponse

      public class IncomingDatagramMessage<O extends UpnpOperation>
      extends UpnpMessage<O>

  A received UDP datagram request or response message, with source address and port.

  Additionally, holds a local address that is reachable from the source address (in the same subnet):

  - When an M-SEARCH is received, we send a LOCATION header back with a reachable (by the remote control point) local address.
  - When a NOTIFY discovery message (can be a search response) is received we need to memorize on which local address it was received, so that the we can later give the remote device a reachable (from its point of view) local GENA callback address.
