Class IlvDefaultAreaRenderer

java.lang.Object

ilog.views.maps.rendering.IlvDefaultAreaRenderer

All Implemented Interfaces:

IlvPersistentObject, IlvFeatureRenderer, Serializable

Direct Known Subclasses:

IlvLabeledAreaRenderer, IlvMapAreaRenderer

public class IlvDefaultAreaRenderer
extends Object
implements IlvFeatureRenderer

This renderer translates a map feature whose geometry is a predefined subclass of IlvMapArea into an IlvGeneralPath, an IlvGraphicPath, or into an IlvGraphicSet of the above if the geometry is an IlvMapArea.

Since:

JViews 3.5

Constructor Detail

IlvDefaultAreaRenderer

public IlvDefaultAreaRenderer()

Initializes an instance of the renderer. In this default mode, the geometries will be translated into IlvGraphicPath.

IlvDefaultAreaRenderer

public IlvDefaultAreaRenderer(boolean useGeneralPath)

Initializes an instance of the renderer with the ability to specify if the geometries have to be translated into an IlvGeneralPath or an IlvGraphicPath.

Parameters:

useGeneralPath - If set to true, the geometries will be translated into IlvGeneralPath. Otherwise, they will be translated into IlvGraphicPath.

IlvDefaultAreaRenderer

public IlvDefaultAreaRenderer(IlvInputStream stream)
                       throws IlvReadFileException

Reads the renderer from an IlvInputStream.

Throws:

IlvReadFileException

Method Detail

setAreaRenderingStyle

public void setAreaRenderingStyle(IlvMapAreaRenderingStyle style)

Sets the rendering style for the areas.

Parameters:

style - The area rendering style.

getAreaRenderingStyle

public IlvMapAreaRenderingStyle getAreaRenderingStyle()

Returns the area rendering style.

makeGraphic

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

Translates an IlvMapFeature into a graphic object. The map feature is transformed using the specified transformation to create the 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.

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

Throws:

IlvMapRenderException - If the renderer can not process the map feature.

IlvCoordinateTransformationException - If a transformation exception occurs.

Since:

JViews 5.0

setUsingGeneralPath

public void setUsingGeneralPath(boolean useGeneralPath)

Specifies if the renderer should produce a IlvGeneralPath or not.

isUsingGeneralPath

public boolean isUsingGeneralPath()

Tells if the renderer is configured to produce IlvGeneralPath or not.

isPersistent

public boolean isPersistent()

Returns true if the renderer must be saved.

Specified by:

isPersistent in interface IlvFeatureRenderer

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.
