Public Types | |
|
typedef boost::shared_ptr< LinkLayer > | LinkLayerPtr |
| Smart pointer that clients should use. | |
Public Member Functions | |
| LinkLayerPtr | thisLinkLayer () |
Gives this pointer as a LinkLayer object. | |
| SimulationEndListenerPtr | thisSimulationEndListener () |
Gives this pointer as a SimulationEndListener object. | |
| virtual void | simulationEndHandler () |
| The function called when the simulation ends. | |
| bool | recvFromLayer (CommunicationLayer::Directions direction, PacketPtr packet, t_uint sendingLayerIdx) |
| Receives a packet from a sending layer. | |
| bool | recvFromMacProtocol (CommunicationLayer::Directions direction, PacketPtr packet) |
| Receives a packet from the MAC protocol associated with this layer to be sent to the default next layer. | |
| bool | channelIsBusy () |
| Queries the underlying physical layer to determine whether the channel is busy. | |
| CommunicationLayer::Types | getLayerType () const |
| Get the layer type of an object. | |
Static Public Member Functions | |
| static LinkLayerPtr | create (NodePtr node, MacProtocolPtr macProtocol) |
A factory method to ensure that all objects are created via new since we are using smart pointers. | |
Protected Member Functions | |
| LinkLayer (NodePtr node, MacProtocolPtr macProtocol) | |
| A constructor. | |
Friends | |
| class | MacProtocol |
This class contains a MAC object and could handle functions like ARP as well.
