WmsLayer

protected WmsLayer(@Nonnull
                   java.util.concurrent.ExecutorService executorService,
                   @Nonnull
                   StyleSupplier<org.geotools.coverage.grid.GridCoverage2D> styleSupplier,
                   @Nonnull

                   @Nonnull
                   Configuration configuration)

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.

configuration - the configuration.

Method Detail

loadImage

protected java.awt.image.BufferedImage loadImage(@Nonnull
                                                 MfClientHttpRequestFactory requestFactory,
                                                 @Nonnull
                                                 MapfishMapContext transformer)
                                          throws java.io.IOException

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.io.IOException

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

prefetchResources

public void prefetchResources(@Nonnull
                              HttpRequestFetcher httpRequestFetcher,
                              @Nonnull
                              MfClientHttpRequestFactory requestFactory,
                              @Nonnull
                              MapfishMapContext transformer,
                              @Nonnull
                              Processor.ExecutionContext context)

Description copied from interface: MapLayer

Cache any needed resources on disk.

Specified by:

prefetchResources in interface MapLayer

Overrides:

prefetchResources in class AbstractGeotoolsLayer

Parameters:

httpRequestFetcher - TODO

requestFactory - client http request factory

transformer - transformer

context - the job ID

getRegistry

public com.codahale.metrics.MetricRegistry getRegistry()

getConfiguration

public Configuration getConfiguration()
