findNearPosition

public java.util.Collection<PointOfInterest> findNearPosition(org.mapsforge.core.model.LatLong point,
                                                              int distance,
                                                              PoiCategoryFilter filter,

                                                              int limit)

Fetch PointOfInterest from underlying storage near a given position. Only the POIs that are allowed by the PoiCategoryFilter object and matching the data pattern will be returned.

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).

patterns - the patterns 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.

getCategoryManager

public PoiCategoryManager getCategoryManager()

Specified by:

getCategoryManager in interface PoiPersistenceManager

Returns:

The persistence manager's category manager for retrieving and editing POI categories.

getPoiFile

public java.lang.String getPoiFile()

Specified by:

getPoiFile in interface PoiPersistenceManager

Returns:

the current POI file.

getPoiFileInfo

public PoiFileInfo getPoiFileInfo()

Specified by:

getPoiFileInfo in interface PoiPersistenceManager

Returns:

the metadata for the current POI file.

getSQLSelectString

protected static java.lang.String getSQLSelectString(PoiCategoryFilter filter,
                                                     int count,
                                                     int version)

Gets the SQL query that looks up POI entries.

Parameters:

filter - The filter object for determining all wanted categories (may be null).

count - Count of patterns to search in points of interest data (may be 0).

version - POI specification version.

Returns:

The SQL query.

setCategoryManager

public void setCategoryManager(PoiCategoryManager categoryManager)

Sets this manager's PoiCategoryManager for retrieving and editing POI categories.

Specified by:

setCategoryManager in interface PoiPersistenceManager

Parameters:

categoryManager - The category manager to be set.

stringToTags

protected static java.util.Set<org.mapsforge.core.model.Tag> stringToTags(java.lang.String data)
