Package jmri.jmrix.mrc

Class MrcTrafficController

java.lang.Object

jmri.jmrix.mrc.MrcTrafficController

All Implemented Interfaces:

MrcInterface

Direct Known Subclasses:

MrcPacketizer

public abstract class MrcTrafficController
extends Object
implements MrcInterface

Converts Stream-based I/O to/from MRC messages. The "MrcInterface" side sends/receives message objects.

The connection to a MrcPortController is via a pair of *Streams, which then carry sequences of characters for transmission. Note that this processing is handled in an independent thread.

This handles the state transitions, based on the necessary state in each message.

getCabNumber

public int getCabNumber()

status

public abstract boolean status()

Specified by:

status in interface MrcInterface

isXmtBusy

public abstract boolean isXmtBusy()

Is there a backlog of information for the outbound link? This includes both in the program (e.g. the outbound queue) and in the command station interface (e.g. flow control from the port).

Monitor the number of MRC messaages received across the interface. This includes the messages this client has sent.

Returns:

count of messages received

getReceivedByteCount

public int getReceivedByteCount()

Monitor the number of bytes in MRC messaages received across the interface. This includes the messages this client has sent.

Returns:

count of bytes in received messages

getTransmittedMsgCount

public int getTransmittedMsgCount()

Monitor the number of MRC messages transmitted across the interface.

Returns:

count of messages sent

getAdapterMemo

public MrcSystemConnectionMemo getAdapterMemo()

setAdapterMemo

public void setAdapterMemo(MrcSystemConnectionMemo memo)

getUserName

public String getUserName()

getSystemPrefix

public String getSystemPrefix()
