public class TLcdAISPolygon extends Object implements ILcd3DEditablePolygon, ILcdRing
A polygon that delegates to an internal polygon. This allows varying the concrete class of the internal polygon. The typical use is to set either a TLcdLonLatHeightPolygon or a TLcdXYZPolygon as the delegate. As such, any class inheriting from TLcdAISPolygon can accommodate both geodetic or cartesian polygons.

  • Constructor Details

    • TLcdAISPolygon

      public TLcdAISPolygon()
      The default constructor does not set the polygon to delegate to. It is required to call 'set3DEditablePolygon' before any of the ILcd3DEditablePolygon methods are called.

    • TLcdAISPolygon

      public TLcdAISPolygon(TLcdAISPolygon aPolygon)
      Copy constructor. Takes a clone of the delegate polygon in aPolygon.
      Parameters:
      aPolygon -
