Library: ilvmaps
The instances of the predefined subclasses IlvMapSegment
can be rendered by an IlvDefaultFeatureRenderer
or by an IlvDefaultCurveRenderer
.
|
pure virtual |
Returns a copy of the object.
IlvMapGeometry
that must be deleted by the user. Implements IlvMapCurve.
Implemented in IlvMapSegmentString, IlvMapLineString, IlvMapLinearSegment, IlvMapCurveString, IlvMapArcString, and IlvMapArcSegment.
|
pure virtual |
Returns the end point of the segment.
Implemented in IlvMapSegmentString, IlvMapLineString, IlvMapLinearSegment, IlvMapCurveString, IlvMapArcString, and IlvMapArcSegment.
|
pure virtual |
Returns the number of intersections between this segment and an horizontal half line.
This function is used for point inclusion tests of IlvMapRing
.
point | The point at the right end of the horizontal half line. |
1
if the point is on the segment, 2
if the point is not on the segment. If the point is on the segment where the tangent is not horizontal, the intersection should not be counted. Implemented in IlvMapLineString, IlvMapLinearSegment, IlvMapCurveString, IlvMapArcString, and IlvMapArcSegment.
|
pure virtual |
Returns the start point of the segment.
Implemented in IlvMapSegmentString, IlvMapLineString, IlvMapLinearSegment, IlvMapCurveString, IlvMapArcString, and IlvMapArcSegment.
|
pure virtual |
Sets the end point of the segment.
end | The end point. |
Implemented in IlvMapSegmentString, IlvMapLineString, IlvMapLinearSegment, IlvMapCurveString, IlvMapArcString, and IlvMapArcSegment.
|
pure virtual |
Sets the start point of the segment.
start | The start point. |
Implemented in IlvMapSegmentString, IlvMapLineString, IlvMapLinearSegment, IlvMapCurveString, IlvMapArcString, and IlvMapArcSegment.
