Class DefaultLayerSourceDescriptor

java.lang.Object
  org.esa.beam.framework.ui.layer.DefaultLayerSourceDescriptor

All Implemented Interfaces:

LayerSourceDescriptor

public class DefaultLayerSourceDescriptor
extends Object
implements LayerSourceDescriptor

The DefaultLayerSourceDescriptor provides metadata and a factory method for a LayerSource.

Instances of this class are created by reading the extension configuration of the extension point "layerSources" in the module.xml.

Example 1:

    <extension point="beam-visat-rcp:layerSources">
      <layerSource>
          <id>shapefile-layer-source</id>
          <name>ESRI Shapefile</name>
          <description>Displays shapes from an ESRI Shapefile</description>
          <class>org.esa.beam.visat.toolviews.layermanager.layersrc.shapefile.ShapefileLayerSource</class>
      </layerSource>
    </extension>
 

Example 1:

    <extension point="beam-visat-rcp:layerSources">
      <layerSource>
          <id>bluemarble-layer-source</id>
          <name>NASA Blue Marble;/name>
          <description>Adds NASA Blue Marble image layer to the background.</description>
          <layerType>org.esa.beam.worldmap.BlueMarbleLayerType</class>
      </layerSource>
    </extension>
