Class LnPacketizerStrict

java.lang.Object

jmri.jmrix.loconet.LnTrafficController

jmri.jmrix.loconet.LnPacketizer

jmri.jmrix.loconet.LnPacketizerStrict

All Implemented Interfaces:

LocoNetInterface

public class LnPacketizerStrict
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)
