public class TLcdCompositeModelHeightProviderFactory extends Object implements ILcdModelHeightProviderFactory
ILcdModelHeightProviderFactory tries to create an
ILcdHeightProvider using a given list of other
ILcdModelHeightProviderFactory instances. The first
ILcdModelHeightProviderFactory that creates a height provider
prevails.
A class that requires a height provider based on a different types of models could construct a suitable factory as follows:
// Create a list of height provider factories that may be relevant
// for different models and different properties.
List<ILcdModelHeightProviderFactory> factories = new ArrayList<ILcdModelHeightProviderFactory>();
factories.add(new TLcdRasterModelHeightProviderFactory());
...
// Create a composite height provider factory.
ILcdModelHeightProviderFactory factory =
new TLcdCompositeModelHeightProviderFactory(factories);

properties. The returned height provider is determined by the implementation,
the ILcdModel and the given properties.createHeightProvider in interface ILcdModelHeightProviderFactoryaModel - an ILcdModel for which a height provider is created.aRequiredProperties - the required properties. The properties can be retrieved using a
String key describing the property type. When not all required properties
are used, an exception is thrown. aRequiredProperties may be empty but should
not be null. When an implementation of this interface uses a required
property, it should always remove it from the list of required properties. When the
ILcdHeightProvider is actually made, implementations should verify that
the list of required properties is empty (and all required properties are used).aOptionalProperties - the optional properties. The properties can be retrieved using a
String key describing the property type. The optional properties may or may
not be used by the implementation. aOptionalProperties may be empty but
should not be null.null when elevation
is not supported or when no valid height provider can be created.TLcdMissingPropertyException - when the implementation misses a necessary property.TLcdUnsupportedPropertyException - when a required property is not used by the
implementation.TLcdModelHeightProviderFactoryUtil
