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 Detail

DefaultMessage

public DefaultMessage(byte[] body,
                      int offset,
                      java.lang.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 Detail

getBody

public byte[] getBody(boolean countTransmission,
                      byte 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 - AX.25 protocol ID 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
