Method Detail

getInstance

public static KMLShapeRepository getInstance()

setQueryField

public void setQueryField(java.lang.String queryField)

getCachedGeoData

public GeoData getCachedGeoData(java.lang.String cacheId)

Description copied from interface: MapObjectRepository

Retrieve the GeoData from the cache. The repository is responsible to cache the geometry data. If cache is missing, it should read it from file system and reset the cache and then returns the data object.

Specified by:

getCachedGeoData in interface MapObjectRepository<MapShape>

Parameters:

cacheId - The cache Id

Returns:

loadObjects

public java.lang.String loadObjects(java.lang.String path,
                                    java.lang.Integer shapeType,
                                    java.util.Map<java.lang.String,java.lang.String> queryName)

Description copied from interface: MapObjectRepository

Load objects from a specified location with specified config object. If the shapeType is already defined in file, then ignore the parameter. Otherwise, assign the type for each shape loaded from the path.

Specified by:

loadObjects in interface MapObjectRepository<MapShape>

Parameters:

path - The path to the location where the file located.

shapeType - An integer representing the shape category / shape type for the shapes that are saved into repository.

queryName - A map object contains name-value pair. Example: use queryField as the key and kml path as the value

Returns:

A string as key to access the loaded object later.

loadObjects

public java.lang.String loadObjects(java.lang.String path,
                                    java.lang.Integer shapeType)

Description copied from interface: MapObjectRepository

Load objects from a specified location. If the shapeType is already defined in file, then ignore the parameter. Otherwise, assign the type for each shape loaded from the path.

Specified by:

loadObjects in interface MapObjectRepository<MapShape>

Parameters:

path - The path to the location where the file located.

shapeType - An integer representing the shape category / shape type for the shapes that are saved into repository.

Returns:

A string as key to access the loaded object later.

getLookupKey

public java.lang.String getLookupKey(LookupRequest request)

Description copied from interface: GeoDataRequestResultVisitor

The lookup key generated for a given query.

Specified by:

getLookupKey in interface GeoDataRequestResultVisitor<MapShape>

Returns:

A string represents the key to the lookup result of this query.
