All Implemented Interfaces:

ILcdModelHeightProviderFactory, Iterable<ILcdModelHeightProviderFactory>

public class TLcyCompositeModelHeightProviderFactory
extends TLcyGenericComposite<ILcdModelHeightProviderFactory>
implements ILcdModelHeightProviderFactory

A composite implementation of ILcdModelHeightProviderFactory according to the composite design pattern.

When creating a new TLcyCompositeModelHeightProviderFactory using the default constructor (see TLcyCompositeModelHeightProviderFactory()), the created instance will only work on/with the ILcdModelHeightProviderFactorys registered on this composite instance (see addModelHeightProviderFactory(com.luciad.util.height.ILcdModelHeightProviderFactory) and removeModelHeightProviderFactory(com.luciad.util.height.ILcdModelHeightProviderFactory)).

When creating a new TLcyCompositeModelHeightProviderFactory using the constructor specifying an ILcyLucyEnv instance (see TLcyCompositeModelHeightProviderFactory(com.luciad.lucy.ILcyLucyEnv), the created instance will work on the Lucy back-end services. It will use all registered ILcdModelHeightProviderFactory instances of the Lucy back-end, adding and/or removing an ILcdModelHeightProviderFactory will add/remove the ILcdModelHeightProviderFactory as service from Lucy, ... .

Creating an ILcdHeightProvider using the back-end based implementation can be done by creating a new instance of this class:

 //Create a new instance whenever you need it.
 TLcyCompositeModelHeightProviderFactory factory = new TLcyCompositeModelHeightProviderFactory( aLucyEnv );
 ILcdHeightProvider provider = factory.createHeightProvider( aModel, aRequiredPropertiesSFCT, aOptionalProperties );
 //There is no need to keep a reference to the composite instance, you can create a new one
 //the next time you would need it
 factory = null;
 

To retrieve a more detailed explanation of the required and optional properties, see ILcdModelHeightProviderFactory.

Constructor Details

TLcyCompositeModelHeightProviderFactory

public TLcyCompositeModelHeightProviderFactory()

Default constructor.

The created instance will only work on the ILcdModelHeightProviderFactory instances registered to it. If you want to use all registered ILcdModelHeightProviderFactory instances of the Lucy back-end, use TLcyCompositeModelHeightProviderFactory(com.luciad.lucy.ILcyLucyEnv) instead.

See Also:

• TLcyCompositeModelHeightProviderFactory(com.luciad.lucy.ILcyLucyEnv)

TLcyCompositeModelHeightProviderFactory

public TLcyCompositeModelHeightProviderFactory(ILcyLucyEnv aLucyEnv)

Construct a TLcyCompositeModelHeightProviderFactory working on the Lucy back-end

It will use all ILcdModelHeightProviderFactory instances registered to the back-end, and adding and/or removing ILcdModelHeightProviderFactorys to/from this TLcyCompositeModelHeightProviderFactory will respectively add/remove it as service from the back-end.

If you want to create a TLcyCompositeModelHeightProviderFactory which does not use the back-end, use TLcyCompositeModelHeightProviderFactory() instead.

Parameters:

aLucyEnv - The Lucy back-end.

• TLcyCompositeModelHeightProviderFactory()
• ILcyLucyEnv.addService(Object, int)
• ILcyLucyEnv.removeService(Object)

Method Details

addModelHeightProviderFactory

public void addModelHeightProviderFactory(ILcdModelHeightProviderFactory aModelHeightProviderFactory)

Adds the given ILcdModelHeightProviderFactory to the list of registered model height provider factories.

If the constructor specifying an ILcyLucyEnv is used, the ILcdModelHeightProviderFactory will be registered as a service on the Lucy back-end (see ILcyLucyEnv.addService(Object, int)). When calling ILcyLucyEnv.getServices(Class) afterwards, aModelHeightProviderFactory will only be included in the returned list when the requested class was ILcdModelHeightProviderFactory.class.
Note: if you want to remove the registered ILcdModelHeightProviderFactory afterwards, use removeModelHeightProviderFactory(com.luciad.util.height.ILcdModelHeightProviderFactory) and not ILcyLucyEnv.removeService(Object).

Parameters:

aModelHeightProviderFactory - The model height provider factory to add. Must not be null.

See Also:

• removeModelHeightProviderFactory(com.luciad.util.height.ILcdModelHeightProviderFactory)

removeModelHeightProviderFactory

public void removeModelHeightProviderFactory(ILcdModelHeightProviderFactory aModelHeightProviderFactory)

Removes the given ILcdModelHeightProviderFactory from the list of registered model height provider factories. Nothing will happen if the given factory was never added before.

If the constructor specifying an ILcyLucyEnv is used, the ILcdModelHeightProviderFactory will be removed as service from the Lucy back-end (see ILcyLucyEnv.removeService(Object)).
Note: it is only possible to remove ILcdModelHeightProviderFactory instances which were registered using the addModelHeightProviderFactory(com.luciad.util.height.ILcdModelHeightProviderFactory) method.

Parameters:

aModelHeightProviderFactory - The model height provider factory to remove. Must not be null

createHeightProvider

public ILcdHeightProvider createHeightProvider(ILcdModel aModel,
 Map<String,Object> aRequiredPropertiesSFCT,
 Map<String,Object> aOptionalProperties)
                                        throws TLcdMissingPropertyException,
TLcdUnsupportedPropertyException

Description copied from interface: ILcdModelHeightProviderFactory

Returns a height provider for a given ILcdModel using the given properties. The returned height provider is determined by the implementation, the ILcdModel and the given properties.

Specified by:

createHeightProvider in interface ILcdModelHeightProviderFactory

Parameters:

aModel - an ILcdModel for which a height provider is created.

aRequiredPropertiesSFCT - 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.

Returns:

a height provider if elevation is supported, or null when elevation is not supported or when no valid height provider can be created.

Throws:

TLcdMissingPropertyException - when the implementation misses a necessary property.

TLcdUnsupportedPropertyException - when a required property is not used by the implementation.

getModelHeightProviderFactoryCount

public int getModelHeightProviderFactoryCount()

Returns the number of registered ILcdModelHeightProviderFactory instances.

Returns:

the number of registered ILcdModelHeightProviderFactory instances.

getModelHeightProviderFactory

public ILcdModelHeightProviderFactory getModelHeightProviderFactory(int aIndex)

Returns the ILcdModelHeightProviderFactory at index aIndex.

Parameters:

aIndex - The index: 0 <= aIndex < getModelHeightProviderFactoryCount()

Returns:

the ILcdModelHeightProviderFactory at index aIndex.
