public class LnStreamPortPacketizer extends LnPacketizer
Converts Stream-based I/O to/from LocoNet messages. The "LocoNetInterface" side sends/receives LocoNetMessage objects. The connection to a LnPortController is via a pair of *Streams, which then carry sequences of characters for transmission.Messages come to this via the main GUI thread, and are forwarded back to listeners in that same thread. Reception and transmission are handled in dedicated threads by RcvHandler and XmtHandler objects. Those are internal classes defined here. The thread priorities are:
- RcvHandler - at highest available priority
- XmtHandler - down one, which is assumed to be above the GUI
- (everything else)

isXmtBusy
public boolean isXmtBusy()
Description copied from class:LnPacketizer
Implement abstract method to signal if there's a backlog of information waiting to be sent.- Overrides:
isXmtBusy
in classLnPacketizer
- Returns:
- true if busy, false if nothing waiting to send
-
connectPort
public void connectPort(LnStreamPortController p)
Make connection to existing LnPortController object.- Parameters:
p
- Port controller to connect to. Save this for a later disconnect call
-
disconnectPort
public void disconnectPort(LnStreamPortController p)
Break connection to existing LnPortController object. Once broken, attempts to send via "message" member will fail.- Parameters:
p
- previously connected port
-
startThreads
public void startThreads()
Invoked at startup to start the threads needed here.- Overrides:
startThreads
