Constructor Detail

WmsLayer

protected WmsLayer(java.util.concurrent.ExecutorService executorService,
                   StyleSupplier<org.geotools.coverage.grid.GridCoverage2D> styleSupplier,
                   WmsLayerParam params,
                   com.codahale.metrics.MetricRegistry registry)

Constructor.

Parameters:

executorService - the thread pool for doing the rendering.

styleSupplier - the style to use when drawing the constructed grid coverage on the map.

params - the params from the request data.

registry - the metrics registry.

Method Detail

loadImage

protected java.awt.image.BufferedImage loadImage(MfClientHttpRequestFactory requestFactory,
                                                 MapfishMapContext transformer)
                                          throws java.lang.Throwable

Description copied from class: AbstractSingleImageLayer

Load the image at the requested size for the provided map bounds.

Specified by:

loadImage in class AbstractSingleImageLayer

Parameters:

requestFactory - the factory to use for making http requests

transformer - object containing map rendering information

Throws:

java.lang.Throwable

getParams

public WmsLayerParam getParams()

Get the HTTP params.

Returns:

the HTTP params

supportsNativeRotation

public boolean supportsNativeRotation()

If supported by the WMS server, a parameter "angle" can be set on "customParams" or "mergeableParams". In this case the rotation will be done natively by the WMS.

Specified by:

supportsNativeRotation in interface MapLayer

Overrides:

supportsNativeRotation in class AbstractGeotoolsLayer

Returns:

True if the layer itself takes care of rotating.

getRenderType

public MapLayer.RenderType getRenderType()

Description copied from interface: MapLayer

Specify whether layer should be rendered as PNG, JPEG or SVG.

Returns:

render type

cacheResources

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

Description copied from interface: MapLayer

Cache any needed resources on disk.

Specified by:

cacheResources in interface MapLayer

Overrides:

cacheResources in class AbstractGeotoolsLayer

Parameters:

httpRequestCache - TODO

requestFactory - client http request factory

transformer - transformer
