Specified by:

findNearPosition in interface PoiPersistenceManager

Parameters:

point - LatLong center of the search.

distance - in meters

filter - POI category filter object that helps determining whether a POI should be added to the set or not (may be null).

pattern - the pattern to search in points of interest data (may be null).

limit - max number of PointOfInterest to be returned.

Returns:

Collection of PointOfInterest matching a given PoiCategoryFilter and data pattern near the given position.
