Class IlvDefaultMultiPointRenderer

java.lang.Object

ilog.views.maps.rendering.IlvDefaultMultiPointRenderer

All Implemented Interfaces:

IlvPersistentObject, IlvFeatureRenderer, Serializable

public class IlvDefaultMultiPointRenderer
extends Object
implements IlvFeatureRenderer

This renderer translates a map feature whose geometry implements the IlvMapMultiPointInterface into an IlvGraphicSet of graphic objects. These graphic objects are generated by a renderer for each point of the geometry.

Since:

Perforce JViews 3.0

IlvDefaultMultiPointRenderer

public IlvDefaultMultiPointRenderer(IlvInputStream stream)
                             throws IlvReadFileException

Method Detail

makeGraphic

public IlvGraphic makeGraphic(IlvMapFeature feature,
                              IlvCoordinateTransformation transformation)
                       throws IlvMapRenderException,
                              IlvCoordinateTransformationException

Translates the map feature into a graphic object. Note that this method has been changed since Perforce JViews 5.0. The old method was draw(IlvMapFeature, IlvProjection). In case you have overridden the old draw method, you have to rewrite your method in order to migrate to JViews 5.0.

Specified by:

makeGraphic in interface IlvFeatureRenderer

Parameters:

feature - The map feature to translate.

transformation - The transformation. This parameter should never be null.

Throws:

IlvMapRenderException - If the renderer cannot process the map feature.

IlvCoordinateTransformationException - If a transformation exception occurs.

Since:

JViews 5.0

setPointRenderer

public void setPointRenderer(IlvFeatureRenderer pointRenderer)

Sets the feature renderer used to translate points into graphic objects. By default, the point renderer is an IlvDefaultPointRenderer.

Parameters:

pointRenderer - The point renderer.

getPointRenderer

public IlvFeatureRenderer getPointRenderer()

Returns the point renderer used to translate points into graphic objects.

write

public void write(IlvOutputStream stream)
           throws IOException

Writes the renderer to an IlvOutputStream.

Specified by:

write in interface IlvPersistentObject

Specified by:

write in interface IlvFeatureRenderer

Parameters:

stream - the output stream

Throws:

IOException - thrown when an exception occurs during the write operation for this object.

isPersistent

public boolean isPersistent()

Returns true.

Specified by:

isPersistent in interface IlvFeatureRenderer
