Constructor Detail

IlvDefaultPointRenderer

public IlvDefaultPointRenderer()

Creates an instance of the renderer.

IlvDefaultPointRenderer

public IlvDefaultPointRenderer(IlvInputStream stream)
                        throws IlvReadFileException

Reads a renderer from an IlvInputStream.

Throws:

IlvReadFileException

Method Detail

getPointRenderingStyle

public IlvMapPointRenderingStyle getPointRenderingStyle()

Retrieves the rendering style associated with the renderer.

Since:

JViews 5.0

setPointRenderingStyle

public void setPointRenderingStyle(IlvMapPointRenderingStyle style)

Sets the rendering style for this renderer.

Parameters:

style - The style.

Since:

JViews 5.0

setUsingFontMarker

public void setUsingFontMarker(boolean useFontMarker)

Tells if the renderer should produce an IlvFontMarker or an IlvMarker.

Parameters:

useFontMarker - If true the renderer will produce an IlvFontMarker. If false, the rendered graphic will be an IlvMarker.

Since:

JViews 5.0

IlvMapPointRenderingStyle.setFont(java.awt.Font), IlvMapPointRenderingStyle.setChar(char)

isUsingFontMarker

public boolean isUsingFontMarker()

Tells if the renderer is producing IlvFontMarker or IlvMarker.

Returns:

true if the renderer graphic is an IlvFontMarker, false otherwise.

Since:

JViews 5.0

See Also:

IlvMapPointRenderingStyle.setFont(java.awt.Font), IlvMapPointRenderingStyle.setChar(char)

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 Rogue Wave 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

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
