getLayers

protected final java.util.List<? extends org.geotools.map.Layer> getLayers(MfClientHttpRequestFactory httpRequestFactory,
                                                         MapfishMapContext mapContext,
                                                         boolean isFirstLayer)
                                                                    throws java.lang.Exception

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

isFirstLayer - true indicates this layer is the first layer in the map (the first layer drawn, ie the base layer)

Throws:

java.lang.Exception

loadImage

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

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

Parameters:

requestFactory - the factory to use for making http requests

transformer - object containing map rendering information

isFirstLayer - true indicates this layer is the first layer in the map (the first layer drawn, ie the base layer)

Throws:

java.lang.Throwable
