Class IlvMultiPathDecoration

java.lang.Object

ilog.views.maps.graphic.IlvMultiPathDecoration

All Implemented Interfaces:

IlvPersistentObject, IlvPathDecoration

public class IlvMultiPathDecoration
extends Object
implements IlvPathDecoration, IlvPersistentObject

This class implements a path decoration composed of multiple path decorations.
When drawing, a multipath decoration draws the decorations in the order they are set, and with the following behavior:

• If a decoration is a subclass of IlvClippedPathDecoration, then it will be drawn using a clipped Shape.
• Any other path decorations are drawn calling the standard draw() method of IlvDecoratedPath.

Since:

JViews 5.0

Constructor Detail

IlvMultiPathDecoration

public IlvMultiPathDecoration(IlvInputStream stream)

Creates a new IlvMultiPathDecoration by reading it from a stream.

Parameters:

stream - The stream to read from.

Since:

JViews 8.1

write

public void write(IlvOutputStream stream)
           throws IOException

Writes this decoration to an IlvOutputStream.

Specified by:

write in interface IlvPersistentObject

Parameters:

stream - The output stream to write to.

draw

public void draw(Graphics2D graphics,
                 Shape shape,
                 IlvTransformer t)

Draws the decoration for the specified shape in the specified graphics.

Specified by:

draw in interface IlvPathDecoration

Parameters:

graphics - The Graphics2D to draw in.

shape - The Shape to draw.

t - The viewing transformer.

boundingBox

public IlvRect boundingBox(Shape shape,
                           IlvRect r,
                           IlvTransformer t)

Returns the bounding box of the specified shape, if it is decorated using this decoration.
If r is non-null, the result is put in r and returned, otherwise the result is returned in a newly allocated IlvRect.

Specified by:

boundingBox in interface IlvPathDecoration

Parameters:

shape - The shape whose bounding box is to be computed.

r - The IlvRect that will contain the result.

t - The transformer for this bounding box.

isZoomable

public boolean isZoomable()

Returns true if this path decoration is zoomable.

Specified by:

isZoomable in interface IlvPathDecoration

equivalentWidth

public double equivalentWidth(IlvTransformer t)

Returns an equivalent line width for the specified transformer.

Specified by:

equivalentWidth in interface IlvPathDecoration

Parameters:

t - The transformer to compute the equivalent width.

Returns:

The equivalent width.
