IGeometryCollection.GeometriesChanged Method

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 .NET]
Public Sub GeometriesChanged ( _
)
[C#]
public void GeometriesChanged (
);
[C++]
HRESULT GeometriesChanged(
void
);

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

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.
