Class TLspMGCPLayerFactory

java.lang.Object
com.luciad.format.mgcp.view.lightspeed.TLspMGCPLayerFactory
All Implemented Interfaces:
ILspLayerFactory
@LcdService(service=ILspLayerFactory.class, priority=20001) public final class TLspMGCPLayerFactory extends Object implements ILspLayerFactory

A Lightspeed Layer factory which can create layers for MGCP 2.0 compliant models. Models are MGCP compliant when the data model descriptor has a data property "FCODE" or similar ("f-code", "fCode"). This includes models decoded by TLcdMGCPModelDecoder, but also SHP files that have such a property.

The returned layer is configured with a scale range and model query config in order not to overload the map. You can change these settings directly on the returned TLspLayer.

  • Base features, such as primary roads, cities, woods, and water, are always visible.
  • More feature types, such as roads, rivers, and railways, become visible between the scales 1:100000 and 1:400000.
  • All features are visible once users zoom in below scale 1:100000.
  • Labels become visible from map scale 1:100000 upwards.

To use this factory you can consult the tutorial.
If you want to apply custom styling you can follow this guide.

  • Method Details

    • createLayers

      public Collection<ILspLayer> createLayers(ILcdModel aModel)
      Description copied from interface: ILspLayerFactory
      Creates one or more ILspLayer objects for the given model.

      Note that this method should not be called if ILspLayerFactory.canCreateLayers(com.luciad.model.ILcdModel) returns false; the results are undefined in this case.

      In most typical scenarios, this method will only create a single ILspLayer instances for a given model. In such cases, the ALspSingleLayerFactory provides a convenient abstract base class for layer factory implementations. An example of when it might be useful to return multiple layers is a model that describes objects moving along a certain trajectory. The layer factory might return one layer which represents the trajectories as polylines, and another which represents the current positions of the objects as point icons.

      Specified by:
      createLayers in interface ILspLayerFactory
      Parameters:
      aModel - the model for which layers should be created
      Returns:
      a collection of layers representing the given model

    • canCreateLayers

      public boolean canCreateLayers(ILcdModel aModel)
      Description copied from interface: ILspLayerFactory
      Determines whether or not this layer factory is capable of creating layers for the given model. If this method returns false, the result of calling ILspLayerFactory.createLayers(com.luciad.model.ILcdModel) with the same parameters is undefined.
      Specified by:
      canCreateLayers in interface ILspLayerFactory
      Parameters:
      aModel - the model for which layers should be created
      Returns:
      true if this factory can create layers for aModel, or false otherwise
