com.nutiteq.layers.UTFGridRasterTileLayer

public class UTFGridRasterTileLayer
extends RasterTileLayer

A special raster layer with UTFGrid interaction. The layer needs
additional data source for UTF grid data and can used to query
nearest feature info (tooltips) around a specified point.

Constructor Detail

UTFGridRasterTileLayer

public UTFGridRasterTileLayer(long cPtr,
                              boolean cMemoryOwn)

UTFGridRasterTileLayer

public UTFGridRasterTileLayer(TileDataSource rasterDataSource,
                              TileDataSource utfGridDataSource)

Method Detail

getCPtr

public static long getCPtr(UTFGridRasterTileLayer obj)

finalize

protected void finalize()

Overrides:

finalize in class RasterTileLayer

delete

public void delete()

Overrides:

delete in class RasterTileLayer

swigCreatePolymorphicInstance

public static UTFGridRasterTileLayer swigCreatePolymorphicInstance(long cPtr,
                                                                   boolean cMemoryOwn)

Creates a polymorphic instance of the given native object. This is used internally by the SDK.

clearTileCaches

public void clearTileCaches(boolean all)

Description copied from class: TileLayer

Clear layer tile caches. This will release memory allocated to tiles.

Overrides:

clearTileCaches in class RasterTileLayer

Parameters:

all - True if all tiles should be released, otherwise only preloading (invisible) tiles are released.

getTooltips

public StringMap getTooltips(MapPos mapPos,
                             boolean waitForData)

Locates and returns tooltips around the given map point.

Parameters:

mapPos - The map position for the tooltips.

waitForData - If true, then missing data is loaded and the call may block for several seconds. If false, then only cached/preloaded data is used.

Returns:

The attribute map of tooltips.

swigGetClassName

public java.lang.String swigGetClassName()

Returns the actual class name of this object. This is used internally by the SDK.

Overrides:

swigGetClassName in class RasterTileLayer

Returns:

The class name of this object.

swigGetDirectorObject

public java.lang.Object swigGetDirectorObject()

Returns the connected director object. This is used internally by the SDK.

Overrides:

swigGetDirectorObject in class RasterTileLayer

Returns:

The connected director object or null if director is not connected.
