Constructor Details

TLcyCompositeCameraLinkerFactory

public TLcyCompositeCameraLinkerFactory()

Default constructor.

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

• TLcyCompositeCameraLinkerFactory(ILcyLucyEnv)

TLcyCompositeCameraLinkerFactory

public TLcyCompositeCameraLinkerFactory(ILcyLucyEnv aLucyEnv)

Construct a TLcyCompositeCameraLinkerFactory working on the Lucy back-end.

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

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

Parameters:

aLucyEnv - The Lucy back-end

Method Details

canCreateCameraLinker

public boolean canCreateCameraLinker(ILcyGenericMapComponent<? extends ILcdView,? extends ILcdLayer> aMapComponent,
 String aType,
 List<Object> aObjects,
 List<ILcdModel> aModels)

Consults the leaf ALcyCameraLinkerFactory instances to see if this composite factory can create an ALcyCameraLinker. It respects the priority of the ALcyCameraLinkerFactory instances: factories with a higher priority will be consulted before factories with a lower priority.

Parameters:

aMapComponent - The map component in which the camera linker should link the camera.

aType - The camera type. See general javadoc of this class.

aObjects - The objects to track. See general javadoc of this class.

aModels - The models belonging to the objects. Should have same size as aObjects.

Returns:

true if it can create a camera linker, false if not.

createCameraLinker

public ALcyCameraLinker createCameraLinker(ILcyGenericMapComponent<? extends ILcdView,? extends ILcdLayer> aMapComponent,
 String aType,
 List<Object> aObjects,
 List<ILcdModel> aModels)

This composite implementation consults all the leaf ALcyCameraLinkerFactory instances to create an ALcyCameraLinker. It respects the priority of the ALcyCameraLinkerFactory instances: factories with a higher priority will be consulted before factories with a lower priority.

Parameters:

aMapComponent - The map component in which the camera linker should link the camera.

aType - The camera type. See general javadoc of this class.

aObjects - The objects to track. See general javadoc of this class.

aModels - The models belonging to the objects. Should have same size as aObjects.

Returns:

The newly created camera linker, can never be null.

Throws:

IllegalArgumentException - When no camera linker factory compatible with the given parameters is part of this composite factory, an exception will be thrown. Therefore we suggest to only call this method if #canCreateCameraLinker returned true for the given parameters.
