ILcdAltitudeProvider

public class TLcdGXYViewBasedTerrainElevationProvider
extends TLcdViewBasedTerrainElevationProvider<ILcdGXYView>

This class is the default implementation of TLcdViewBasedTerrainElevationProvider for ILcdGXYViews.

This mediator keeps track of terrain models in the ILcdGXYView and adds/removes them to/from the specified model based terrain elevation provider.

Note that a view must be set using setGXYView(ILcdGXYView) before the mediator can add/remove terrain models to/from the model based elevation provider. If no view is set, the model based elevation provider remains unchanged. The method TLcdViewBasedTerrainElevationProvider.retrieveElevationAt(ILcdPoint, ILcdGeoReference) shall probably return the unknown elevation value for all specified points. This depends on the implementation of the specified model based elevation provider.

Constructor Details

TLcdGXYViewBasedTerrainElevationProvider

public TLcdGXYViewBasedTerrainElevationProvider(ALcdModelBasedTerrainElevationProvider aTerrainElevationProvider)

Constructs a new view based terrain elevation provider which is based on an ALcdModelBasedTerrainElevationProvider. This model based elevation provider will be used to retrieve the actual elevation.

Note that a view must be set using setGXYView(ILcdGXYView) before the mediator can add/remove terrain models to/from the model based elevation provider. If no view is set, the model based elevation provider remains unchanged. The method TLcdViewBasedTerrainElevationProvider.retrieveElevationAt(ILcdPoint, ILcdGeoReference) shall probably return the unknown elevation value for all specified points. This depends on the implementation of the specified model based elevation provider.

Parameters:

aTerrainElevationProvider - The provider used to retrieve the actual elevation.

• TLcdViewBasedTerrainElevationProvider.setTerrainElevationProvider(ALcdModelBasedTerrainElevationProvider)

TLcdGXYViewBasedTerrainElevationProvider

public TLcdGXYViewBasedTerrainElevationProvider(ILcdGXYView aGXYView,
 ALcdModelBasedTerrainElevationProvider aTerrainElevationProvider)

Constructs a new view based terrain elevation provider which is based on an ALcdModelBasedTerrainElevationProvider. The specified view provides the terrain models and the model based elevation provider provides the actual elevation.

Parameters:

aGXYView - The view containing the raster layers.

aTerrainElevationProvider - The provider used to retrieve the actual elevation.

See Also:

• TLcdViewBasedTerrainElevationProvider.setTerrainElevationProvider(ALcdModelBasedTerrainElevationProvider)

Method Details

getView

public ILcdGXYView getView()

Returns the view containing the layers.

This method is identical to getGXYView().

Overrides:

getView in class TLcdViewBasedTerrainElevationProvider<ILcdGXYView>

Returns:

the view containing the layers.

See Also:

• TLcdViewBasedTerrainElevationProvider.setView(com.luciad.view.ILcdView)

setView

public void setView(ILcdGXYView aView)

Set the view containing the raster layers.

This method is identical to setGXYView(ILcdGXYView).

Overrides:

setView in class TLcdViewBasedTerrainElevationProvider<ILcdGXYView>

Parameters:

aView - The view containing the raster layers.

See Also:

• TLcdViewBasedTerrainElevationProvider.getView()

getGXYView

public ILcdGXYView getGXYView()

Returns the view containing the raster layers.

This method is identical to getView().

Returns:

the view containing the raster layers.

See Also:

• setGXYView(ILcdGXYView)

setGXYView

public void setGXYView(ILcdGXYView aGXYView)

Set the view containing the raster layers.

This method is identical to setView(ILcdGXYView).

Parameters:

aGXYView - The view containing the raster layers.

See Also:

• getGXYView()

isClassTraceOn

public static boolean isClassTraceOn()

Deprecated.

This method has been deprecated. It is recommended to use the standard Java logging framework directly.

Returns true if tracing is enabled for this class.

Returns:

true if tracing is enabled for this class, false otherwise.

setClassTraceOn

public static void setClassTraceOn(boolean aClassTraceOn)

Deprecated.

This method has been deprecated. It is recommended to use the standard Java logging framework directly.

Enables tracing for all instances of this class. If the argument is true then all log messages are recorded, otherwise only the informative, warning and error messages are recorded.

Parameters:

aClassTraceOn - if true then all log messages are recorded, otherwise only the informative, warning and error messages are recorded.
