public class WMSLayer
extends AbstractCachedTileSourceLayer

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

getMenuEntries

public 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

Returns:

menu actions for this layer

getTileSource

protected AbstractTMSTileSource getTileSource(ImageryInfo info)

Specified by:

getTileSource in class AbstractTileSourceLayer

Parameters:

info - imagery info

Returns:

TileSource for specified ImageryInfo

getHeaders

protected Map<String,String> getHeaders(TileSource tileSource)

Overrides:

getHeaders in class AbstractTileSourceLayer

isProjectionSupported

public boolean isProjectionSupported(Projection proj)

Description copied from class: Layer

allows to check whether a projection is supported or not

Overrides:

isProjectionSupported in class Layer

Parameters:

proj - projection

Returns:

True if projection is supported for this layer

nameSupportedProjections

public String nameSupportedProjections()

Description copied from class: Layer

Specify user information about projections

Overrides:

nameSupportedProjections in class Layer

Returns:

User readable text telling about supported projections

projectionChanged

public void projectionChanged(Projection oldValue,
                              Projection newValue)

Specified by:

projectionChanged in interface ProjectionChangeListener

Overrides:

projectionChanged in class Layer

getTileLoaderClass

protected Class<? extends TileLoader> getTileLoaderClass()

Specified by:

getTileLoaderClass in class AbstractCachedTileSourceLayer

getCacheName

protected String getCacheName()

Specified by:

getCacheName in class AbstractCachedTileSourceLayer

getCache

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

Returns:

cache region for WMS layer

isReprojectionPossible

private boolean isReprojectionPossible()
