public class WMSLayer
extends AbstractCachedTileSourceLayer<AbstractWMSTileSource>

This is a layer that grabs the current screen from an WMS server. The data fetched this way is tiled and managed to the disc to reduce server load.

Constructor Detail

WMSLayer

public WMSLayer(ImageryInfo info)

Constructs a new WMSLayer.

Parameters:

info - ImageryInfo description of the layer

Method Detail

createDisplaySettings

protected TileSourceDisplaySettings createDisplaySettings()

Description copied from class: AbstractTileSourceLayer

This method creates the TileSourceDisplaySettings object. Subclasses may implement it to e.g. change the prefix.

Overrides:

createDisplaySettings in class AbstractTileSourceLayer<AbstractWMSTileSource>

Returns:

The object.

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<AbstractWMSTileSource>

Returns:

menu actions for this layer

getTileSource

protected AbstractWMSTileSource 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<AbstractWMSTileSource>

Returns:

TileSource for specified ImageryInfo

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<AbstractWMSTileSource>

Returns:

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

projectionChanged

public void projectionChanged(Projection oldValue,
                              Projection newValue)

Specified by:

projectionChanged in interface ProjectionChangeListener

Overrides:

projectionChanged in class AbstractTileSourceLayer<AbstractWMSTileSource>

chooseProjection

private Projection chooseProjection(Projection requested)

selectProjection

private Projection selectProjection(Projection proj)

getTileLoaderClass

protected java.lang.Class<? extends TileLoader> getTileLoaderClass()

Specified by:

getTileLoaderClass in class AbstractCachedTileSourceLayer<AbstractWMSTileSource>

getCacheName

protected java.lang.String getCacheName()

Specified by:

getCacheName in class AbstractCachedTileSourceLayer<AbstractWMSTileSource>

getCache

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

Returns:

cache region for WMS layer
