Constructor Detail

IlpGeographicPolyPoints

protected IlpGeographicPolyPoints()

Note that _numsegments can validly be 0. For IlpPolyline, this is valid if and only if _from == _to.

Method Detail

getNumberOfPoints

public abstract int getNumberOfPoints()

Returns the number of points in the polyline.

Returns:

The number of points

getPosition

public IlpGeographicPosition getPosition(int index)

Returns a specific point (0 <= index < getNumberOfPoints()). The point should not be modified.

getPositions

public IlpGeographicPosition[] getPositions()

Returns the array of points. Neither the array nor the points contained therein should be modified.

setPositions

protected void setPositions(IlpGeographicPosition[] pos)

Sets the array of points.
