Constructor Detail

AbstractFeatureSourceLayer

public AbstractFeatureSourceLayer(java.util.concurrent.ExecutorService executorService,
                                  FeatureSourceSupplier featureSourceSupplier,
                                  StyleSupplier<org.geotools.data.FeatureSource> styleSupplier,
                                  boolean renderAsSvg,
                                  AbstractLayerParams params)

Constructor.

Parameters:

executorService - the thread pool for doing the rendering.

featureSourceSupplier - a function that creates the feature source. This will only be called once.

styleSupplier - a function that creates the style for styling the features. This will only be called once.

renderAsSvg - is the layer rendered as SVG?

params - the parameters for this layer

Method Detail

setStyle

public final void setStyle(StyleSupplier style)

getFeatureSource

public final org.geotools.data.FeatureSource<?,?> getFeatureSource(@Nonnull
                                                                   MfClientHttpRequestFactory httpRequestFactory,
                                                                   @Nonnull

Get the feature source (either load from the supplier or return the cached source).

Parameters:

httpRequestFactory - The factory for making http requests.

mapContext - The map context.

getLayers

Description copied from class: AbstractGeotoolsLayer

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

Specified by:

getLayers in class AbstractGeotoolsLayer

Parameters:

httpRequestFactory - the factory for making http requests

mapContext - the map transformer

setFeatureCollection

public final void setFeatureCollection(org.geotools.data.simple.SimpleFeatureCollection featureCollection)

getRenderType

public final MapLayer.RenderType getRenderType()

Description copied from interface: MapLayer

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

Returns:
