Interface TransmittingConnector

All Known Implementing Classes:

AGWPEConnector, AprsIsConnector, FileTNCConnector, KissOverTcpConnector, SerialTNCConnector, SslAprsIsConnector, UdpSubmitConnector

public interface TransmittingConnector

This class extends the basic capabilities of being a port connector by specifying the methods usable to transmit AX.25 frames through this port.

Author:

Andrew Pavlin, KA2DDO

Method Summary

Modifier and Type	Method	Description
int	getAcceptableProtocolsMask()	Get the bitmask of AX.25 protocols supported by this port.
String	getCallsign()	For ports that have an AX.25 address (callsign), report the callsign associated with the port (used for transmissions initiated through this port instead of digipeated).
int	getCapabilities()	Specify what capabilities a port of this type has.
Connector.PortStats	getStats()	Get the current statistics for this PortConnector instance.
boolean	hasCapability(int capMask)	Test if this Connector has the specified capability or capabilities.
boolean	isOpen()	Reports whether this Connector has an open connection to its port.
void	sendFrame(AX25Frame frame)	Transmit an AX.25 frame through this port.

Method Details

isOpen

boolean isOpen()

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

Returns:

boolean true if Connector is open

getStats

Connector.PortStats getStats()

Get the current statistics for this PortConnector instance.

Returns:

PortStats for this port.

sendFrame

void sendFrame(AX25Frame frame)
        throws IOException

Transmit an AX.25 frame through this port. May fail silently if port is not configured for transmission (receive-only). May also queue for later transmission if timeslotting is used. Should be thread-safe so that multiple simultaneous calls do not interleave bytes of different frames.

Parameters:

frame - AX25Frame object to transmit

Throws:

IOException - if transmit failed for any reason other than a receive-only port

getCallsign

String getCallsign()

For ports that have an AX.25 address (callsign), report the callsign associated with the port (used for transmissions initiated through this port instead of digipeated). By default, returns empty string. Subclasses are expected to override this.

Returns:

callsign String, or null if no associated callsign

getCapabilities

int getCapabilities()

Specify what capabilities a port of this type has.

Returns:

bitmask of capability flags

hasCapability

boolean hasCapability(int capMask)

Test if this Connector has the specified capability or capabilities.

Parameters:

capMask - bitmask of capabilities to be tested for

Returns:

boolean true if this port has all the specified capabilities in its capability set

getAcceptableProtocolsMask

int getAcceptableProtocolsMask()

Get the bitmask of AX.25 protocols supported by this port. Bit positions correspond to the Enum.ordinal() value of the ProtocolFamily enum.

Returns:

protocol bitmask, or 0 for no AX.25 protocols supported
