New Filter based on event

Hi, is that possible to have a new filter that filter positions after an event ? like device stoped.

Because we have trackers that have ignition attribute on all positions, so the filters that we like do not work , like duplicate and distance, so we would like to filter duplicate, distance positions only after device get event stoped.

You would have to change the code.

FilterHandler.java ?

is it like position.getEvent() == "Stoped" , can you tell how do I need to set it ?

to get event is almost like this ?

@Override
protected boolean filterPosition(Position position) {

    // Get the device ID
    long deviceId = position.getDeviceId();

    // Check if it's a "stopped" event
    if (position.getAttributes().containsKey("event")) {
        String event = position.getAttributes().get("event").toString();
        if ("stopped".equals(event)) {
            stoppedState.put(deviceId, true); // Mark as stopped
        } else if ("moving".equals(event)) {
            stoppedState.put(deviceId, false); // Mark as moving
        }
    }

    // Apply filtering only if the device is stopped
    if (stoppedState.getOrDefault(deviceId, false)) {
        // Check if the new position is identical to the last processed position
        Position lastPosition = lastPositions.get(deviceId);
        if (lastPosition != null 
                && lastPosition.getLatitude() == position.getLatitude()
                && lastPosition.getLongitude() == position.getLongitude()
                && lastPosition.getSpeed() == position.getSpeed()) {
            return true; // Filter (discard) the repeated position
        }

        // Update the last processed position
        lastPositions.put(deviceId, position);
    }

    return false; // Do not filter (accept) the position
}
