    • acceptAX25Frame

      public int acceptAX25Frame(AX25Frame frame)
      Indicate whether the specified message should be displayed or used to determine if a station should be displayed (if recursively called from acceptStation()).
      Specified by:
      acceptAX25Frame in class Filter
      Parameters:
      frame - the timestamped AX25 frame record to analyze
      Returns:
      RESULT_xxx constant indicating if message information should be displayed
    • acceptMessage

      public int acceptMessage(AX25Message msg)
      Indicate whether the specified message should be displayed or used to determine if a station should be displayed (if recursively called from acceptStation()).
      Specified by:
      acceptMessage in class Filter
      Parameters:
      msg - the APRS Message record to analyze
      Returns:
      RESULT_xxx constant indicating if message information should be displayed
    • acceptStation

      public int acceptStation(StationState ss)
      Indicate whether the specified station should be displayed. The acceptMessage() and acceptAX25Frame() methods may be called to assist in the determination.
      Specified by:
      acceptStation in class Filter
      Parameters:
      ss - StationState record to analyze
      Returns:
      RESULT_xxx constant indicating if station information should be displayed
    • getFilterTypeTagName

      public String getFilterTypeTagName()
      Report a tag name used to look up the labelling for an editor panel for this editor instance in a ResourceBundle of translated names.
      Specified by:
      getFilterTypeTagName in class Filter
      Returns:
      String to use in looking up form label for this filter's editor
    • getFilterHelpTagName

    • setToPassall

      public void setToPassall()
      Reset the filter to a configuration that would pass the maximum amount of messages, packets, and stations.
      Specified by:
      setToPassall in class Filter
    • canRejectSome

      public boolean canRejectSome()
      Specifies that this filter may reject some stations, messages, and/or frames. Used to tell combining filters whether a sub-filter is in passall mode and therefore doesn't need to be checked for every call to the combiner, thereby saving CPU time when filtering when most filters are in passall mode.
      Overrides:
      canRejectSome in class Filter
      Returns:
      boolean true if this filter is currently capable of rejecting something
