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 Detail

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
