Tells this geometry collection that some of its geometries have been altered. Use this method on polylines, polygons and multipatches after directly editing one of its parts.
[Visual Basic 6.0] Sub GeometriesChanged
[Visual Basic .NET] Public Sub GeometriesChanged ( _ )
[C#] public void GeometriesChanged ( );
[Java] public void geometriesChanged ( ) throws IOException, AutomationException
[C++] HRESULT GeometriesChanged( void );
GeometriesChanged flags that the geometries have been changed. It also marks a top level geometry as being non-simple. Use it when manipulating the parts of a geometry directly (for example, rotating a ring). The top level geometry won't know that its cached envelope, length, centroid, etc. are invalid until this method is used.
