All Implemented Interfaces:

Serializable, Cloneable, Comparable<AX25Message>, CommentedMessage, SendableMessage

public class DefaultMessage
extends Message
implements SendableMessage

This class defines a default message (suitable to contain any other type of APRS message that YAAC doesn't explicitly understand). The lead character of such messages is kept in the comment instead of being stripped off.

Constructor Summary

Constructors

Constructor	Description
DefaultMessage(byte[] body, int offset, String tp, long rcvTimestamp)	Create a DefaultMessage from the bytes in a byte array (such as the body of an AX25Frame).
DefaultMessage(char type)	Create an empty DefaultMessage with the specified message type character.

Method Summary

Modifier and Type	Method	Description
void	disableForTransmit()	Specify that message should no longer be transmitted.
byte[]	getBody(boolean countTransmission, ProtocolFamily protocolId, AX25Frame frame)	Get an ASCII-text version of this message, suitable for transmitting.
Set<ProtocolFamily>	getProtocols()	Get the protocol family or families that this message corresponds to, so ports that don't support all protocols will not forward inappropriate packets.
boolean	isEnabled()	Test if message should still be transmitted.

Constructor Details

DefaultMessage

public DefaultMessage(byte[] body,
 int offset,
 String tp,
 long rcvTimestamp)

Create a DefaultMessage from the bytes in a byte array (such as the body of an AX25Frame).

Parameters:

body - byte array containing the transmission format of the message

offset - index into the array where the message starts

tp - String of third-party routing information (or null if this was not routed over another network)

rcvTimestamp - the time (in milliseconds in Jan 1970 UTC) when this message was received

DefaultMessage

public DefaultMessage(char type)

Create an empty DefaultMessage with the specified message type character.

Parameters:

type - char type code of this message.

Method Details

getBody

public byte[] getBody(boolean countTransmission,
 ProtocolFamily protocolId,
 AX25Frame frame)

Get an ASCII-text version of this message, suitable for transmitting.

Specified by:

getBody in interface SendableMessage

Parameters:

countTransmission - number of times the message has been transmitted

protocolId - ProtocolFamily to format this message in

frame - AX25Frame into which the message will be placed; the decoded message (as opposed to the byte array encoding) should be stored into the field frame.parsedAX25Msg

Returns:

byte array of message

See Also:

• AX25Frame.parsedAX25Msg

isEnabled

public boolean isEnabled()

Test if message should still be transmitted.

Specified by:

isEnabled in interface SendableMessage

Returns:

boolean true if message should still be transmitted

disableForTransmit

public void disableForTransmit()

Specify that message should no longer be transmitted.

Specified by:

disableForTransmit in interface SendableMessage

getProtocols

public Set<ProtocolFamily> getProtocols()

Get the protocol family or families that this message corresponds to, so ports that don't support all protocols will not forward inappropriate packets.

Overrides:

getProtocols in class Message

Returns:

array of supported ProtocolFamily enums
