Interface Summary

Interface	Description
CumulativeFilter	This filter accumulates the results of several filters and determines the overall pass/fail based on the aggregation of the sub-filters' results.
FilterChangeListener	This listener is for classes who need to know when the settings of a filter have changed.
IrrelevantToPlaybackFilter	This tag interface marks a Filter subclass that is not suitable for filtering the loading of log files for playback.
MonitoringFilter	This interface defines extra methods a Filter that updates itself from real-time data must implement to allow turning on and off the updating.
PersistingFilter	Extra methods required for a Filter that can persist its values across instance creations and YAAC restarts.

Class Summary

Class	Description
AddresseeFilter	Filter based on the addressee in an APRS Text Message (':').
AreaFilter	This class implements the area 'a' filter as defined by the APRS-IS server filter standards.
CumulativeBooleanAndFilter	This filter accumulates the results of several filters.
CumulativeBooleanOrFilter	This filter accumulates the results of several filters.
DestinationFilter	This filter selects messages based on their destination AX.25 address.
DigipeatFilter	This implements the "d/" filter for APRS-IS server connections, matching any digipeater on the path.
EntryFilter	This class implements the I-gate entry point 'e' filter as defined for APRS-IS servers.
Filter	This abstract class defines the basic concept of a message filter.
FilterExpressionParser	This class takes a string expression in the format used for APRS-IS feed filters, and converts it into a hierarchy of Filter objects that will provide that filtering.
FirstDigipeatFilter	This filter accepts or rejects messages based on the first station to relay the message.
FromFilter	Filter packets by the originating station's callsign using a preset match list.
LastDigipeatFilter	This filter accepts or rejects messages based on the last station to transmit the message.
LocalStationFilter	This filter optionally eliminates all messages from excessively distant stations.
MessageContentFilter	Filter messages based on their containing (or not containing) specific elements in their messages, or specific strings in their free-text comments.
MicEFilter	This filter selects messages by the MicE status code.
NotFilter	This filter is a wrapper around another filter, inverting the answer, so a passing result becomes a rejecting result, and vice versa.
ObjectNameFilter	Filter based on the object name in an APRS Object (';') or Item (')') Message.
OperatorPresentFilter	This filter optionally eliminates all messages from unmanned stations.
PacketSourceFilter	This filter selects packets and messages based on which interface port the message entered YAAC through.
PacketTypeFilter	Filter based on the type of APRS packet in the frame.
PlaybackFilter	This filter chooses whether to view real-time only data, log file playback only data, or both.
PriorityFilter	This filter optionally eliminates all routine precedence messages.
RadiusFilter	This class implements a filter based on radius from a specified location (defaulting to the beacon location for the station).
RelativeTimeFilter	This filter selects information based on relative time point boundary.
SendingStationFilter	This filter selects all stations that match (or don't match) an entry in a list of station identifiers.
StationClassFilter	This filter allows selecting stations and messages solely by category of sending station.
SymbolFilter	This filter selects messages by the APRS symbol code, indicated by symbol table ID and symbol type.
ToFilter	Filter packets by the destination station's callsign (tocall) using a preset match list
ValidInvalidFilter	This Filter selects viewing messages that are only valid or only invalid.

Package org.ka2ddo.yaac.filter Description

This package contains classes for marking AX25Frames, AX25Messages (decoded frames), and stations/objects as being of current interest to the user. Dynamically changing filter settings allows the user to look at different subsets of the packet data currently available from the network.
