Interface IlvCrossingAwareObject

All Known Subinterfaces:

IlvParameterizedCrossingAwareObject

All Known Implementing Classes:

IlvSegmentedHyperEdge

public interface IlvCrossingAwareObject

A subclass of IlvGraphic must implement this interface, if it should be able to display crossing graphics (tunnels, jogs, bridges) at the place where lines cross. Crossing aware objects are typically links and hyperedges, i.e. graphic objects that consist of a set of line segments. The bounding box of the crossing aware object should always include all crossing aware segments returned by getCrossingAwareSegments(ilog.views.IlvTransformer).

Since:

JViews 8.1

Method Summary

Modifier and Type	Method and Description
IlvRect	boundingBoxCrossingGraphic(IlvTransformer t) Returns the bounding rectangle of the crossing graphic that belongs to this object.
boolean	containsAtCrossingGraphic(IlvPoint p, IlvPoint tp, IlvTransformer t) Tests if a point lies within the outline of the crossing graphic that belongs to this object.
void	drawCrossingGraphic(Graphics dst, IlvTransformer t) Draws the crossing graphic that belongs to this object.
IlvGraphic	getCrossingAwareGraphic() Returns the corresponding graphic.
IlvCrossingAwareSegment[]	getCrossingAwareSegments(IlvTransformer t) Returns all segments of the object.
IlvGraphic	getCrossingGraphic() Returns the graphic object that draws the crossings.
double	getLineWidth(IlvTransformer t) Returns the line width of the segments of the object.
boolean	isCrossingEnabled() Whether crossings are enabled for the crossing owner.
void	removeAllCrossings(IlvTransformer t) Removes all crossings added at the object for a given transformer.
void	setCrossingAdjusting(boolean adjusting) Starts or end an adjustment session for the crossings.

Method Detail

getCrossingAwareGraphic

IlvGraphic getCrossingAwareGraphic()

Returns the corresponding graphic. If a subclass of IlvGraphic implements this interface, it should return the this handle.

getCrossingAwareSegments

IlvCrossingAwareSegment[] getCrossingAwareSegments(IlvTransformer t)

Returns all segments of the object.

Parameters:

t - The transformer to draw the object.

getLineWidth

double getLineWidth(IlvTransformer t)

Returns the line width of the segments of the object.

Parameters:

t - The transformer to draw the object.

removeAllCrossings

void removeAllCrossings(IlvTransformer t)

Removes all crossings added at the object for a given transformer.

Parameters:

t - The transformer to draw the object.

getCrossingGraphic

IlvGraphic getCrossingGraphic()

Returns the graphic object that draws the crossings.

drawCrossingGraphic

void drawCrossingGraphic(Graphics dst,
                         IlvTransformer t)

Draws the crossing graphic that belongs to this object. Crossing graphics can delegate their draw method to this method if necessary.

Parameters:

dst - The destination Graphics.

t - The transformation used to draw this object.

IlvAbstractCrossingGraphic.draw(java.awt.Graphics, ilog.views.IlvTransformer)

containsAtCrossingGraphic

boolean containsAtCrossingGraphic(IlvPoint p,
                                  IlvPoint tp,
                                  IlvTransformer t)

Tests if a point lies within the outline of the crossing graphic that belongs to this object. Crossing graphics can delegate their contains method to this method if necessary.

Parameters:

p - The point to be tested in the coordinate system of this object.

tp - The point p transformed by the transformer t.

t - The transformation that was applied to this object when it was drawn.

IlvAbstractCrossingGraphic.contains(ilog.views.IlvPoint, ilog.views.IlvPoint, ilog.views.IlvTransformer)

boundingBoxCrossingGraphic

IlvRect boundingBoxCrossingGraphic(IlvTransformer t)

Returns the bounding rectangle of the crossing graphic that belongs to this object. Crossing graphics can delegate their boundingBox method to this method if necessary.

Parameters:

t - The transformer used to draw this object.

See Also:

IlvAbstractCrossingGraphic.boundingBox(ilog.views.IlvTransformer)

setCrossingAdjusting

void setCrossingAdjusting(boolean adjusting)

Starts or end an adjustment session for the crossings.

isCrossingEnabled

boolean isCrossingEnabled()

Whether crossings are enabled for the crossing owner.
