Constructor Detail

MVTLayer

public MVTLayer(ImageryInfo info)

Creates an instance of an MVT layer

Parameters:

info - ImageryInfo describing the layer

Method Detail

getTileLoaderClass

protected java.lang.Class<? extends org.openstreetmap.gui.jmapviewer.interfaces.TileLoader> getTileLoaderClass()

Specified by:

getTileLoaderClass in class AbstractCachedTileSourceLayer<MapboxVectorTileSource>

getCacheName

protected java.lang.String getCacheName()

Specified by:

getCacheName in class AbstractCachedTileSourceLayer<MapboxVectorTileSource>

getCache

public static org.apache.commons.jcs3.access.CacheAccess<java.lang.String,BufferedImageCacheEntry> getCache()

Returns cache region for MVT layer.

Returns:

cache region for MVT layer

Since:

18186

getNativeProjections

public java.util.Collection<java.lang.String> getNativeProjections()

Description copied from class: AbstractTileSourceLayer

Get projections this imagery layer supports natively.

For example projection of tiles that are downloaded from a server. Layer may support even more projections (by reprojecting the tiles), but with a certain loss in image quality and performance.

Specified by:

getNativeProjections in class AbstractTileSourceLayer<MapboxVectorTileSource>

Returns:

projections this imagery layer supports natively; null if layer is projection agnostic.

paint

public void paint(java.awt.Graphics2D g,
                  MapView mv,
                  Bounds box)

Description copied from interface: MapViewPaintable

Paint the dataset using the engine set.

Specified by:

paint in interface MapViewPaintable

Overrides:

paint in class AbstractTileSourceLayer<MapboxVectorTileSource>

Parameters:

g - Graphics

mv - The object that can translate GeoPoints to screen coordinates.

box - Bounding box

getTileSource

protected MapboxVectorTileSource getTileSource()

Description copied from class: AbstractTileSourceLayer

Creates and returns a new TileSource instance depending on ImageryLayer.info specified in the constructor.

Specified by:

getTileSource in class AbstractTileSourceLayer<MapboxVectorTileSource>

Returns:

TileSource for specified ImageryInfo

createTile

public org.openstreetmap.gui.jmapviewer.Tile createTile(MapboxVectorTileSource source,
                                                        int x,
                                                        int y,
                                                        int zoom)

Description copied from class: AbstractTileSourceLayer

Create a new tile. Added to allow use of custom Tile objects.

Overrides:

createTile in class AbstractTileSourceLayer<MapboxVectorTileSource>

Parameters:

source - Tile source

x - X coordinate

y - Y coordinate

zoom - Zoom level

Returns:

The new Tile

getMenuEntries

public javax.swing.Action[] getMenuEntries()

Description copied from class: Layer

Returns list of actions. Action can implement LayerAction interface when it needs to be represented by other menu component than JMenuItem or when it supports multiple layers. Actions that support multiple layers should also have correct equals implementation.

Use Layer.SeparatorLayerAction.INSTANCE instead of new JSeparator

Overrides:

getMenuEntries in class AbstractTileSourceLayer<MapboxVectorTileSource>

Returns:

menu actions for this layer

getData

public VectorDataSet getData()

Get the data set for this layer

finishedLoading

public void finishedLoading(MVTTile tile)

Description copied from interface: MVTTile.TileListener

Called when the MVTTile is finished loading

Specified by:

finishedLoading in interface MVTTile.TileListener

Parameters:

tile - The tile that finished loading
