- Method Detail
  - message
```
void message(CanMessage m)
```
    Called when an outgoing message is sent to the CAN Network.
    
    Parameters:
    
    m - the CanMessage being sent.
  - reply
```
void reply(CanReply m)
```
    Called when an incoming CanFrame is received from the CAN Network.
    
    Parameters:
    
    m - the CanReply being received.
  - addTc
```
default void addTc(TrafficController tcToAdd)
```
    Add a Traffic Controller Listener. Adding here, rather than in a class construction header avoids Leaking Constructor errors.
    
    Parameters:
    
    tcToAdd - The system memo CAN Traffic Controller
  - addTc
```
default void addTc(CanSystemConnectionMemo memoToAdd)
```
    Add a Traffic Controller Listener. Adding here, rather than in a class construction header avoids Leaking Constructor errors.
    
    Parameters:
    
    memoToAdd - The CAN system Connection.
  - removeTc
```
default void removeTc(TrafficController tcToRemove)
```
    Remove a Traffic Controller Listener.
    
    Parameters:
    
    tcToRemove - The system memo CAN Traffic Controller.
  - removeTc
```
default void removeTc(CanSystemConnectionMemo memoToRemove)
```
    Remove a Traffic Controller Listener.
    
    Parameters:
    
    memoToRemove - The CAN system Connection.
