Class IlvDefaultFeatureRenderer

java.lang.Object

ilog.views.maps.IlvDefaultFeatureRenderer

All Implemented Interfaces:

IlvPersistentObject, IlvFeatureRenderer, Serializable

Direct Known Subclasses:

IlvMapCSSRenderer, IlvMIFFeatureRenderer

public class IlvDefaultFeatureRenderer
extends Object
implements IlvFeatureRenderer

This feature renderer can translate all the predefined geometries of Rogue Wave JViews into graphic objects. It dispatches the makeGraphic calls to a specialized feature renderer depending on the geometry of the map feature. Each specialized feature renderer is initialized with a default value, but it can be changed.

Constructor Detail

IlvDefaultFeatureRenderer

public IlvDefaultFeatureRenderer()

Initializes an instance of the renderer.

IlvDefaultFeatureRenderer

public IlvDefaultFeatureRenderer(IlvInputStream stream)
                          throws IlvReadFileException

Reads the renderer from an IlvInputStream.

Throws:

IlvReadFileException - if the format is not correct.

Method Detail

makeGraphic

public IlvGraphic makeGraphic(IlvMapFeature mapFeature,
                              IlvCoordinateTransformation tr)
                       throws IlvCoordinateTransformationException,
                              IlvMapRenderException

Makes an IlvGraphic from a map feature. Note that this method has been changed since Rogue Wave JViews 5.0. The old method was makeGraphic(IlvMapFeature, IlvProjection). In case you have overridden the old makeGraphic method, you have to rewrite your method in order to migrate to JViews 5.0.

Specified by:

makeGraphic in interface IlvFeatureRenderer

Parameters:

mapFeature - The map feature to translate.

tr - The destination Coordinate System of the map feature.

Throws:

IlvMapRenderException - if the renderer cannot process the map feature.

IlvCoordinateTransformationException - if an error occurs during the coordinate transformation.

Since:

JViews 5.0

dispatch

protected IlvGraphic dispatch(IlvMapFeature mapFeature,
                              IlvCoordinateTransformation tr)
                       throws IlvCoordinateTransformationException,
                              IlvMapRenderException

Dispatches a map feature to the renderer specialized to render the feature geometry. Note that this method has been changed since Rogue Wave JViews 5.0. The old method was dispatch(IlvMapFeature, IlvProjection). In case you have overridden the old dispatch method, you have to rewrite your method in order to migrate to JViews 5.0.

Parameters:

mapFeature - The map feature.

tr - The destination Coordinate System of the map feature.

Throws:

IlvMapRenderException - If the renderer cannot process the map feature.

IlvCoordinateTransformationException - If an error occurs during the coordinate transformation.

Since:

JViews 5.0

makeGraphicFromCollection

protected IlvGraphic makeGraphicFromCollection(IlvMapFeature feature,
                                               IlvCoordinateTransformation tr)
                                        throws IlvCoordinateTransformationException,
                                               IlvMapRenderException

This method is called by dispatch() for the map features whose geometries are Collections of subgeometries. Note that this method has been changed since Rogue Wave JViews 5.0. The old method was makeGraphicFromCollection(IlvMapFeature, IlvProjection). In case you have overridden the previous form of this method, you have to rewrite your method in order to migrate to JViews 5.0.

Parameters:

feature - The map feature to be translated.

tr - The destination Coordinate System of the map feature.

Returns:

The created IlvGraphic.

Throws:

IlvMapRenderException - If the renderer cannot process the map feature.

IlvCoordinateTransformationException - If an error occurs during the coordinate transformation.

Since:

JViews 5.0
