Method Summary

Modifier and Type	Method and Description
IlvCrossing	createCrossing(double x, double y, IlvCrossingAwareSegment crossingSegment) Creates a crossing for the segment.
IlvCrossingOwner	getCrossingOwner() Returns the owner of crossings that are registered for this segment.
IlvPoint	getEndPoint() Returns the end point of the segment.
IlvPoint	getStartPoint() Returns the start point of the segment.
boolean	isIncident(IlvCrossingAwareSegment segment) Returns whether this crossing aware segment is incident to the input segment.

Method Detail

getStartPoint

IlvPoint getStartPoint()

Returns the start point of the segment.

getEndPoint

IlvPoint getEndPoint()

Returns the end point of the segment.

getCrossingOwner

IlvCrossingOwner getCrossingOwner()

Returns the owner of crossings that are registered for this segment.

createCrossing

IlvCrossing createCrossing(double x,
                           double y,
                           IlvCrossingAwareSegment crossingSegment)

Creates a crossing for the segment. The crossing is active for the segment. The crossing must store the crossing owner obtained from this segment as active owner, and the crossing owner obtained from the input segment as passive owner.

Parameters:

x - The x coordinate of the crossing.

y - The y coordinate of the crossing.

crossingSegment - The other segment that crosses this segment.

isIncident

boolean isIncident(IlvCrossingAwareSegment segment)

Returns whether this crossing aware segment is incident to the input segment.
