Member Function Documentation

cMessage * SimpleNetwLayer::decapsMsg (  NetwPkt *  msg  )  [protected, virtual]

decapsulate higher layer message from NetwPkt Decapsulates the packet from the received Network packet

NetwPkt * SimpleNetwLayer::encapsMsg (  cMessage *  msg  )  [protected, virtual]

Encapsulate higher layer packet into an NetwPkt. Encapsulates the received ApplPkt into a NetwPkt and set all needed header fields.

void SimpleNetwLayer::handleLowerMsg (  cMessage *  msg  )  [protected, virtual]

Handle messages from lower layer. Redefine this function if you want to process messages from lower layers before they are forwarded to upper layers If you want to forward the message to upper layers please use sendUp which will take care of decapsulation and thelike Implements BasicLayer. Reimplemented in Flood.

void SimpleNetwLayer::handleUpperMsg (  cMessage *  msg  )  [protected, virtual]

Handle messages from upper layer. Redefine this function if you want to process messages from upper layers before they are send to lower layers. For the SimpleNetwLayer we just use the destAddr of the network message as a nextHop To forward the message to lower layers after processing it please use sendDown. It will take care of anything needed Implements BasicLayer. Reimplemented in Flood.
