Detailed Description

The Datalink layer class is an example of the Protocol_Layer design pattern.

This class inherits from the Protocol_Layer and overrides the receive and transmit handlers for the layer. The actual layer processing is performed by the Transmit_Protocol_Handler and the Receive_Protocol_Handler classes.

Definition at line 25 of file Datalink_Layer.h.

Public Member Functions
Datalink_Layer ()
Construct a Datalink layer object.

void Transmit (Protocol_Packet *p_Packet)
This method handles the transmit side processing.

void Handle_Receive (Protocol_Packet *p_Packet)
This method handles the receive side processing.

Private Attributes
Transmit_Protocol_Handler m_transmit_Protocol_Handler
Helper class for handling the transmit side processing for this layer.

Receive_Protocol_Handler m_receive_Protocol_Handler
Helper class for receive side processing for this layer.

Datalink_Layer::Datalink_Layer ( )

Construct a Datalink layer object.
The datalink layer functionality is handled by the Transmit_Protcol_Handler and Receive_Protocol_Handler classes.

void Datalink_Layer::Transmit ( Protocol_Packet * p_Packet ) [virtual]

This method handles the transmit side processing.
The method receives a Protocol_Packet from the upper layer and passes it to the Trasmit_Protocol_Handler. The Transmit_Protocol_Handler handles the processing for this layer and forwards the message to the next lower layer.

void Datalink_Layer::Handle_Receive ( Protocol_Packet * p_Packet ) [virtual]

This method handles the receive side processing.
The method receives a Protocol_Packet from the lower layer and passes it to the Receive_Protocol_Handler. The Receive_Protocol_Handler handles the processing for this layer and forwards the message to the next upper layer.
