LuciadLightspeedClass TLspCompositeLayerFactory

java.lang.Object

com.luciad.view.lightspeed.layer.TLspCompositeLayerFactory

All Implemented Interfaces:

ILspLayerFactory

public class TLspCompositeLayerFactory
extends Object
implements ILspLayerFactory

Composite implementation of ILspLayerFactory. Any number of layer factories can be added to this composite; the createLayers(com.luciad.model.ILcdModel) method will delegate to the first factory in the list whose ILspLayerFactory.canCreateLayers(com.luciad.model.ILcdModel) returns true for the given input model.

Example usage:

To create a composite instance which uses all default available ILspLayerFactory instances, you can use:

    ILspLayerFactory layerFactory =
        new TLspCompositeLayerFactory(TLcdServiceLoader.getInstance(ILspLayerFactory.class));

This will use all layer factories annotated with the @LcdService annotation.

Since:

2012.0

Constructor Summary

Constructors

Constructor and Description
TLspCompositeLayerFactory() Creates a new, empty composite layer factory.
TLspCompositeLayerFactory(ILspLayerFactory... aLayerFactories) Creates a new composite layer factory containing the supplied delegate factories.
TLspCompositeLayerFactory(Iterable<? extends ILspLayerFactory> aLayerFactories) Creates a new composite layer factory that lazily uses the given Iterable to delegate to.

Method Summary

Modifier and Type	Method and Description
boolean	canCreateLayers(ILcdModel aModel) Returns true if there is at least one delegate factory whose canCreateLayer() method also returns true for the given model.
Collection<ILspLayer>	createLayers(ILcdModel aModel) Delegates to the first layer factory whose canCreateLayer() method returns true for the given model.

Constructor Detail

TLspCompositeLayerFactory

public TLspCompositeLayerFactory()

Creates a new, empty composite layer factory. This factory will not be able to create layers until delegate layer factories are added to the layer factory list.

TLspCompositeLayerFactory

public TLspCompositeLayerFactory(Iterable<? extends ILspLayerFactory> aLayerFactories)

Creates a new composite layer factory that lazily uses the given Iterable to delegate to.

Parameters:

aLayerFactories - delegate factories to be added to the composite

TLspCompositeLayerFactory

public TLspCompositeLayerFactory(ILspLayerFactory... aLayerFactories)

Creates a new composite layer factory containing the supplied delegate factories.

Parameters:

aLayerFactories - delegate factories to be added to the composite

Method Detail

getLayerFactories

public List<ILspLayerFactory> getLayerFactories()

Returns the list of delegate layer factories contained in this composite. If the composite does not use an Iterable, delegates can be added or removed by modifying this list.

Returns:

the list of delegate layer factories in this composite

createLayers

public Collection<ILspLayer> createLayers(ILcdModel aModel)

Delegates to the first layer factory whose canCreateLayer() method returns true for the given model.

Specified by:

createLayers in interface ILspLayerFactory

Parameters:

aModel - the model for which a layer should be created

Returns:

a layer created by the selected delegate factory

canCreateLayers

public boolean canCreateLayers(ILcdModel aModel)

Returns true if there is at least one delegate factory whose canCreateLayer() method also returns true for the given model.

Specified by:

canCreateLayers in interface ILspLayerFactory

Parameters:

aModel - the model for which a layer should be created

Returns:

true if at least one of the delegate factories supports the given model
