Class TLspNITFLayerFactory

java.lang.Object
com.luciad.format.nitf.lightspeed.TLspNITFLayerFactory
All Implemented Interfaces:
ILspLayerFactory
@LcdService(service=ILspLayerFactory.class, priority=20000) public class TLspNITFLayerFactory extends Object implements ILspLayerFactory

The default layer factory for NITF models. All models created by the NITF model decoder are supported.

This layer factory returns a layer tree node with two child layers:

  • A layer responsible for painting the vector data from the NITF model which uses a TLspCGMStyler.
  • A layer responsible for painting the raster data from the NITF model.

Both child layers will have the same model, which is the model passed to the createLayers(ILcdModel) method. The layer tree node uses a TLcdModelTreeNode which re-uses the model descriptor from the model passed to the createLayers(ILcdModel) method.

2019.0

    • 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

    • 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
