IPointCollection4 Interface

Provides access to members that manipulate the points of a Multipoint, Path, Ring, Polyline, Polygon, TriangleFan, TriangleStrip, or MultiPatch. Note: the IPointCollection4 interface has been superseded by IPointCollection5. Please consider using the more recent version.

Product Availability

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

Members

Description
Method AddPoint Adds a vertex to a Path, Ring, Polyline, or Polygon; or adds a reference to the input point to a Multipoint, TriangleFan, or TriangleStrip.
Method AddPointCollection Adds copies of points in the input point collection to this Path, Ring, Polyline, or Polygon; or adds references to the points in the collection to this Multipoint, TriangleFan, or TriangleStrip.
Method AddWKSPointZs Adds vertices/points to this Path, Ring, Polyline, Polygon, Multipoint, TriangleFan, Triangles, TriangleStrip, or MultiPatch.
Read-only property EnumVertices A new enumerator for this point collection.
Read-only property IndexedEnumVertices An indexed vertex enumerator for this point collection.
Method InsertPointCollection Inserts copies of points, from the input point collection, as vertices into this Path, Ring, Polyline, or Polygon; or references to points in the input point collection into this Multipoint, TriangleFan, or TriangleStrip.
Method InsertWKSPointZs Inserts new vertices/points into this Path, Ring, Polyline, Polygon, Multipoint, TriangleFan, Triangles, TriangleStrip, or MultiPatch.
Read-only property Point A copy of the ith vertex of a Path, Ring, Polyline, or Polygon; or a reference to the ith point of a Multipoint, TriangleFan, or TriangleStrip.
Read-only property PointCount The number of points in the collection.
Method QueryPoint Queries for a point in the PointCollection at given index.
Method QueryWKSPointZs Copies vertices/points coordinates to the array of point structures.
Method RemovePoints Removes vertices from a Path, Ring, Polyline, or Polygon, or references to points from a Multipoint, TriangleFan, or TriangleStrip.
Method ReplacePointCollection Replaces vertices/points within a PointCollection.
Method ReplacePoints Replaces vertices/points within a PointCollection.
Method SetPointCollection Replaces all vertices of this Path, Ring, Polyline, or Polygon with copies of the points in the input collection; or all points of this Multipoint, TriangleFan, or TriangleStrip with references to points from the input collection.
Method SetWKSPointZs Replaces all vertices/points of this Path, Ring, Polyline, Polygon, Multipoint, TriangleFan, Triangles, TriangleStrip, or MultiPatch with new ones.
Method UpdatePoint Changes the ith vertex or point to be a copy of the input point.

CoClasses that implement IPointCollection4

CoClasses and Classes Description
MultiPatch A collection of surface patches.
Multipoint An ordered collection of points; optionally has measure, height and ID attributes.
Path A sequence of connected segments.
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.
Ring An area bounded by one, closed sequence of connected segments; optionally has measure, height and ID attributes at each vertex.
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 A collection of 3D triangles, where each consecutive triplet of vertices defines a new triangle
TriangleStrip A continuous 3D strip of triangles, where each triangle after the first shares an edge with the preceding triangle.
