Constructor Detail

AbstractGeotoolsLayer

protected AbstractGeotoolsLayer(java.util.concurrent.ExecutorService executorService,
                                AbstractLayerParams params)

Constructor.

Parameters:

executorService - the thread pool for doing the rendering.

params - the parameters for this layer

Method Detail

tryAddLayer

public final com.google.common.base.Optional<MapLayer> tryAddLayer(MapLayer newLayer)

Description copied from interface: MapLayer

Attempt to add the layer this layer so that both can be rendered as a single layer.

For example: 2 WMS layers from the same WMS server can be combined into a single WMS layer and the map can be rendered with a single WMS request.

Specified by:

tryAddLayer in interface MapLayer

Parameters:

newLayer - the layer to combine with this layer. The new layer will be rendered below the current layer.

Returns:

If the two layers can be combined then a map layer representing the two layers will be returned. If the two layers cannot be combined then Option.absent() will be returned.

prepareRender

public void prepareRender(MapfishMapContext transformer)

Description copied from interface: MapLayer

Render the layer to the graphics2D object.

Specified by:

prepareRender in interface MapLayer

Parameters:

transformer - the map transformer containing the map bounds and size.

render

public final void render(java.awt.Graphics2D graphics2D,
                         MfClientHttpRequestFactory clientHttpRequestFactory,
                         MapfishMapContext transformer)

Description copied from interface: MapLayer

Render the layer to the graphics2D object.

Specified by:

render in interface MapLayer

Parameters:

graphics2D - the graphics object.

clientHttpRequestFactory - The factory to use for making http requests.

transformer - the map transformer containing the map bounds and size.

getLayers

protected abstract java.util.List<? extends org.geotools.map.Layer> getLayers(MfClientHttpRequestFactory httpRequestFactory,
                                                                              MapfishMapContext transformer)
                                                                       throws java.lang.Exception

Get the DataStore object that contains the data for this layer.

Parameters:

httpRequestFactory - the factory for making http requests

transformer - the map transformer

Throws:

java.lang.Exception

supportsNativeRotation

public boolean supportsNativeRotation()

Description copied from interface: MapLayer

Indicate if the layer supports native rotation (e.g. WMS layers with the "angle" parameter).

Specified by:

supportsNativeRotation in interface MapLayer

Returns:

True if the layer itself takes care of rotating.

getName

public final java.lang.String getName()

Description copied from interface: MapLayer

The layer name.

Specified by:

getName in interface MapLayer

getFailOnError

public final boolean getFailOnError()

getLayerTransformer

protected final MapfishMapContext getLayerTransformer(MapfishMapContext transformer)

If the layer transformer has not been prepared yet, do it.

Parameters:

transformer - the transformer

cacheResources

public void cacheResources(HttpRequestCache httpRequestCache,
                           MfClientHttpRequestFactory clientHttpRequestFactory,
                           MapfishMapContext transformer)

Description copied from interface: MapLayer

Cache any needed resources on disk.

Specified by:

cacheResources in interface MapLayer

Parameters:

httpRequestCache - TODO

clientHttpRequestFactory - client http request factory

transformer - transformer
