public class AprsIsConnector
extends TNCConnector
implements java.lang.Runnable, java.lang.Thread.UncaughtExceptionHandler, PortFailureReportListener, NeedsAppVersionInfoIfc

This class defines a potentially bidirectional connection to an APRS-IS server. New functionality includes support for SOCKS5 proxy server relay connections (RFC1928), supporting username/password authentication (RFC1929). TODO: support GSSAPI authentication (RFC1961)

Method Detail

setAppVersion

public void setAppVersion(java.lang.String name,
                          java.lang.String version)

Sets the name and version of the containing application.

Specified by:

setAppVersion in interface NeedsAppVersionInfoIfc

Parameters:

name - String name of the application (cannot contain whitespace)

version - String version of the application (cannot contain whitespace)

configure

public void configure(PortConfig config)
               throws java.io.IOException,
                      java.lang.IllegalArgumentException

Update the configuration of the connector to match the updated setup.

Specified by:

configure in class PortConnector

Parameters:

config - PortConfig defining new port settings

Throws:

java.io.IOException - if interface changes could not be applied

java.lang.IllegalArgumentException - if type information is invalid for changing the settings of this PortConnector

isOpen

public boolean isOpen()

Reports whether this PortConnector has an open connection to its port.

Specified by:

isOpen in class Connector

Returns:

boolean true if PortConnector is open

run

public final void run()

Private internal method used to read the incoming APRS messages from the socket connection to the selected APRS-IS server.

Specified by:

run in interface java.lang.Runnable

getBitRate

public int getBitRate()

Get the bit transmission rate on this port.

Overrides:

getBitRate in class TNCConnector
