IlvMapLinearSegment

public IlvMapLinearSegment(IlvCoordinate start,
                           IlvCoordinate end)

Creates a linear segment by specifying the start and end point.

Parameters:

start - The start point.

end - The end point.

Method Detail

getStartPoint

public IlvCoordinate getStartPoint()

Returns the start point of this segment.

Specified by:

getStartPoint in interface IlvMapSegment

Returns:

The start point of this segment.

setStartPoint

public void setStartPoint(IlvCoordinate start)

Sets the start point of this segment.

Specified by:

setStartPoint in interface IlvMapSegment

Parameters:

start - The start point of this segment.

getEndPoint

public IlvCoordinate getEndPoint()

Returns the end point of this segment.

Specified by:

getEndPoint in interface IlvMapSegment

Returns:

The end point of this segment.

setEndPoint

public void setEndPoint(IlvCoordinate end)

Sets the end point of this segment.

Specified by:

setEndPoint in interface IlvMapSegment

Parameters:

end - The end point of this segment.

getHorizontalIntersectionCount

public int getHorizontalIntersectionCount(IlvCoordinate p)

Returns the number of intersections between an horizontal half line defined by its right extremity point and the segment. This function is used for point inclusion tests of IlvMapRingInterface.
