public class MessageFilterPane extends JTabbedPane implements AprsMessageListener, FontChangeListener
This class defines the filters and UI for selectively capturing the contents of Messages. Of incoming messages, only the following go to this intercept path:
  • by originating station, doing either whitelist or blacklist
  • by destination addressee (self, bulletin groups)
  • by regular expression pattern match on message body
Matching messages are logged to a specified ASCII text log file in a specified format, including:
  • CSV or TSV delimiting
  • entire message body or groups specified by regular expression
  • date/time of receipt (user-specified format and timezone)
  • sending station
  • lat/lon of sending station

The format is converted from a text string to an ordered list of objects defining the output line. The object types are:

  • String - literal text to append to the line
  • \{ - literal text of "{"
  • {0} - the entire message body (indicated by Integer zero)
  • {timeformat} - the date/time of receipt, as formatted by SimpleDateFormat
  • {C} - sending callsign
  • {A} - addressee
  • {L} - sending latitude, using standard display format
  • {l} - sending longitude, using standard display format
  • {L0#.####} - sending latitude, using zeros and # characters per DecimalFormat
  • {l0#.####} - sending longitude, using zeros and # characters per DecimalFormat
  • {1} through {9} - regular expression groups from the pattern matching regex (indicated by Integer objects)

Messages are also appended to a JTextArea which can be copy-and-pasted to the system clipboard for inclusion in other applications.
