EDN: ESRI Developer Network
Provides access to members that can be used for accessing, adding and removing individual geometries of a multi-part geometry (Multipoint, Polyline, Polygon, MultiPatch, and GeometryBag).
A Collection of Geometry parts. For Multipoints, TriangleFans, and TriangleStrips, the Geometry parts are Points. For Polylines, the Geometry parts are Paths. For Polygons, the Geometry parts are Rings. For MultiPatches, the Geometry parts are TriangleFans, TriangleStrips, or Rings. For GeometryBags, the Geometry parts are any IGeometry object.
The GeometryCollection can be used to access, manipulate, add, insert, remove, and set specific parts of a composite geometry.
| Description | ||
|---|---|---|
 |
AddGeometries | Adds references to the specified geometries. This method is intended for internal use only. |
|
AddGeometry | Adds a reference to the input geometry either at the end, or before, or after the specified index. |
|
AddGeometryCollection | Adds references to geometries in the input collection. |
|
GeometriesChanged | 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. |
 |
Geometry | A reference to the ith geometry. |
|
GeometryCount | The number of geometries in this collection. |
|
InsertGeometries | Inserts at the specified index references to some number of geometries in the input array. This method is intended for internal use only. |
|
InsertGeometryCollection | Inserts at the specified index references to all if the geometries in the input collection. |
|
QueryGeometries | Populates the array with references to a sub-sequence of geometries. This method is intended for internal use only. |
|
RemoveGeometries | Removes references to some geometries from this collection. |
|
SetGeometries | Replaces all geometries in the collection with the specified number of references to those in the input array. This method is intended for internal use only. |
|
SetGeometryCollection | Replaces all geometries in the collection with references to geometries from the input collection. |
| CoClasses and Classes | Description |
|---|---|
| GeoEllipse (esriMilitaryAnalyst) | A spheroidal ellipse. |
| GeometryBag | An ordered collection of objects that support the IGeometry interface. |
| GeoPolygon (esriMilitaryAnalyst) | A spheroidal polygon. |
| GeoPolyline (esriMilitaryAnalyst) | A spheroidal polyline. |
| MultiPatch | A collection of surface patches. |
| Multipoint | An ordered collection of points; optionally has measure, height and ID attributes. |
| Polygon | A collection of rings ordered by their containment relationship; optionally has measure, height and ID attributes. |
| Polyline | An ordered collection of paths; optionally has measure, height and ID attributes. |
| TriangleFan | A continuous 3D fan of triangles, where each triangle after the first shares an edge with the preceding triangle, and all triangles share a common pivot point. |
| Triangles | |
| TriangleStrip | A continuous 3D strip of triangles, where each triangle after the first shares an edge with the preceding triangle. |
