public static Predicate<AisPacket> samplingFilter(Integer minDistanceInMeters,
                                                  Long minDurationInMS)

Sampling filter predicate.

Parameters:

minDistanceInMeters - the min distance in meters

minDurationInMS - the min duration in ms

Returns:

the predicate

parseSourceFilter

@Deprecated
public static Predicate<AisPacket> parseSourceFilter(String filter)

Deprecated.

Replaced by Predicate<AisPacket> parseExpressionFilter(String filter)

Parameters:

filter - the filter

Returns:

predicate predicate

parseExpressionFilter

public static Predicate<AisPacket> parseExpressionFilter(String filter)

Parse expression filter predicate.

Parameters:

filter - the filter

Returns:

the predicate

targetSamplingFilter

public static Predicate<AisPacket> targetSamplingFilter(Integer minDistance,
                                                        Long minDuration)

Similar to the SamplingFilter except that it applies the sampling per MMSI target

Parameters:

minDistance - the minimum distance between two packets per target

minDuration - the minimum time in ms between two packets per target

Returns:

the target sampling filter predicate

duplicateFilter

public static Predicate<AisPacket> duplicateFilter(long windowSize)

Removes duplicates within the given time window

Parameters:

windowSize - the sampling rate in ms

Returns:

the target sampling filter predicate
