public class UltimeterRawMessage
extends Message

This class represents a message decoded from a Peet Bros Ultimeter weather station (APRS protocol specification chapter 12). It also can decode Peet Bros messages from a local weather station without going through APRS first, so this same code can be used in both use cases.

Constructor Details

UltimeterRawMessage

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

Constructor for Ultimeter raw weather message when decoding a binary AX.25 frame.

Parameters:

body - byte array of frame body

offset - int array index offset for start of message (non-zero for encapsulated messages)

tp - third-party relay String for encapsulated messages, or null for no third-party wrapper

rcvTimestamp - Unix time when message was actually received by YAAC

Method Details

parseWeatherLine

public static boolean parseWeatherLine(String line,
 Map<Enum,Object> currentWeather,
 long msgRcptTime)

Decode a line of text supposedly containing one of the Ultimeter weather station ASCII text formats, as documented on the Peet Bros website.

Parameters:

line - String containing a weather report

currentWeather - a Map to store the weather parameters in

msgRcptTime - time weather sentence was received in Java milliseconds since Jan 1 19780 UTC

Returns:

boolean true if message was successfully parsed

isSymbolInferred

public boolean isSymbolInferred()

Report whether the non-null APRS symbol reported by this message is explicit or inferred from destination or source callsign. Intended to be overridden by message types which can infer a symbol but can't explicitly specify the symbol.

Overrides:

isSymbolInferred in class Message

Returns:

boolean true if symbol is inferred
