LuciadFusionClass TLspFusionGeometryProvider

java.lang.Object

com.luciad.fusion.client.view.lightspeed.TLspFusionGeometryProvider

Deprecated.

Since 2017.0 support for coverages of type VECTOR has been superseded with other mechanisms. Please refer to the Fusion migration guide for more information.

public final class TLspFusionGeometryProvider
extends Object

Provides access to the geometry of Fusion vector features.

Fusion vector features often have multiple geospatial representations; a same feature may for example be represented by a point at world-scale and a polygon at a more detailed zoom level. The ILcdShapeList interface of these features only provide access to the geometry of the feature at the most detailed level. The API provided by this class allows to retrieve the geospatial representation of features at the current view level.

Two mechanisms are provided for accessing feature geometry:

• A simple method for retrieving geometry: getGeometry(Object, com.luciad.view.lightspeed.TLspContext)
• A set of ALspStyleTargetProvider instances, one provider for each supported geometry type and one union provider

Consult the class javadoc of TLspFusionVectorLayerBuilder for more information about working with Fusion vector data in combination with an ILspStyler.

Since:

2012.1

Method Detail

getGeometry

public static Object getGeometry(Object aModelObject,
                                 TLspContext aContext)

Deprecated.

Extract the geometry associated with the element at the current level for the tiles that are currently available.

Returned shapes

An ILcdShapeList containing a shape for each visible element of the feature:

• ILcdPoint: for point elements.
• ILcdShapeList: for line elements. It contains ILcdPolyline shapes that describe the available parts of the line feature.
• ILfnTiledSurface: for area elements. See ILfnTiledSurface.getOutlines() and ILfnTiledSurface.getFills() for details.
• ILcdText: for text elements.

The top-level object will also implement ILcdDataObject.

Restrictions

• It is possible that you only get a part of the original geometry: if not all tiles geometry were visible, or if some tiles have not yet been loaded.
• It is possible that the geometry is presented in separate parts, e.g. if a tile in the middle is not yet loaded.
• Parts of adjacent wiles will always be merged together into one part.
• It is possible that extra points will be present that were not present in the original geometry. These points are interpolated points and will not be visible.

Parameters:

aModelObject - the model object (view-independent)

aContext - a context defining the layer and view for which to get the view-dependent geometry

Returns:

the view-dependent (tiled) geometry, can be null
