ilog.views.maps.graphic.IlvClippedPathDecoration

ilog.views.maps.graphic.IlvShapedPathDecoration

All Implemented Interfaces:

IlvPersistentObject, IlvPathDecoration, Serializable

public class IlvShapedPathDecoration
extends IlvClippedPathDecoration
implements IlvPersistentObject

A path decoration that is a Shape repeated at specified intervals.
A zoomable IlvShapedPathDecoration has its decoration and decoration repetition interval zooming depending on the zoom level of the view.
A non-zoomable IlvShapedPathDecoration displays its decoration at a fixed size.

Constructor Detail

IlvShapedPathDecoration

public IlvShapedPathDecoration(Shape decoration,
                               double interval,
                               boolean zoomable)

Constructs a new IlvShapedPathDecoration, with the specified paint, no stroke, and a default phase and flatness of 0.

Parameters:

decoration - The decoration to repeat.

interval - The interval at which the decoration is repeated.

zoomable - If true, the decoration is zoomable.

IlvShapedPathDecoration

public IlvShapedPathDecoration(Shape decoration,
                               double interval,
                               double phase,
                               double flatness,
                               boolean zoomable)

Constructs a new IlvShapedPathDecoration with the specified flattening factor.

Parameters:

decoration - The decoration to repeat.

interval - The interval at which the decoration is repeated.

phase - The phase for decoration drawing (like dash phase).

flatness - The flatness used to iterate on the decorated path.

zoomable - If true, the decoration is zoomable.

IlvShapedPathDecoration

public IlvShapedPathDecoration(IlvInputStream stream)
                        throws IlvReadFileException

Reads an IlvShapedPathDecoration from the specified stream.

Throws:

IlvReadFileException

Method Detail

write

public void write(IlvOutputStream stream)
           throws IOException

Writes this IlvShapedPathDecoration to the specified stream.

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvClippedPathDecoration

Parameters:

stream - The output stream.

Throws:

IOException - If an error occurs when writing.

getDecoration

public Shape getDecoration()

Returns the shape used as decoration of this path decoration.

getInterval

public double getInterval()

Returns the interval of the decoration repetition.

getPhase

public double getPhase()

Returns the phase before drawing the first decoration.

draw

public void draw(Graphics2D graphics,
                 Shape subshape,
                 double phase,
                 IlvTransformer t)

Draws the decoration for the specified shape, which is a sub shape of the original shape.

Specified by:

draw in class IlvClippedPathDecoration

Parameters:

graphics - The Graphics2D to draw in.

subshape - The Shape to draw.

phase - The phase to draw this decoration.

t - The viewing transformer.

equivalentWidth

public double equivalentWidth(IlvTransformer t)

Returns an equivalent line width to this path decoration, if it is drawn using the specified transformer.

Specified by:
