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 Note: the IPointCollection4 interface has been superseded by IPointCollection5.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

	Name	Description
	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.
	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.
	AddPoints	Adds copies of the input points as vertices to this Path, Ring, Polyline, or Polygon; or references to the input points to this Multipoint, TriangleFan, or TriangleStrip. This method is intended for internal use only.
	AddWKSPoints	Adds vertices to this Path, Ring, Polyline, or Polygon, or adds new points to this Multipoint, TriangleFan, or TriangleStrip.
	AddWKSPointZs	Adds vertices/points to this Path, Ring, Polyline, Polygon, Multipoint, TriangleFan, Triangles, TriangleStrip, or MultiPatch.
	EnumVertices	A new enumerator for this point collection.
	GetPoints	Populates an array with references to points in the Multipoint. The QueryPoints method on IPointCollection makes copies of the points. This method is intended for internal use only.
	IndexedEnumVertices	An indexed vertex enumerator for this point collection.
	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.
	InsertPoints	Inserts copies of the input points as vertices into a Path, Ring, Polyline, or Polygon; or references to the input points into a Multipoint, TriangleFan, or TriangleStrip. This method is intended for internal use only.
	InsertWKSPoints	Inserts new vertices/points into this Path, Ring, Polyline, Polygon, Multipoint, TriangleFan, TriangleStrip, or MultiPatch.
	InsertWKSPointZs	Inserts new vertices/points into this Path, Ring, Polyline, Polygon, Multipoint, TriangleFan, Triangles, TriangleStrip, or MultiPatch.
	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.
	PointCount	The number of points in the collection.
	QueryPoint	Queries for a point in the PointCollection at given index.
	QueryPoints	Copies some points to an existing array of points. This method is intended for internal use only.
	QueryWKSPoints	Copies vertices'/points' coordinates to the array of point structures.
	QueryWKSPointZs	Copies vertices/points coordinates to the array of point structures.
	RemovePoints	Removes vertices from a Path, Ring, Polyline, or Polygon, or references to points from a Multipoint, TriangleFan, or TriangleStrip.
	ReplacePointCollection	Replaces vertices/points within a PointCollection.
	ReplacePoints	Replaces vertices/points within a PointCollection.
	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.
	SetPoints	Replaces all existing vertices of this Path, Ring, Polyline, or Polygon with copies of the input points; or all existing points of this Multipoint, TriangleFan, or TriangleStrip with references to the input points (for C++ and VB users only).
	SetWKSPoints	Replaces all vertices of this Path, Ring, Polyline, or Polygon with new ones, or replaces all points of this Multipoint, TriangleFan, or TriangleStrip with new ones.
	SetWKSPointZs	Replaces all vertices/points of this Path, Ring, Polyline, Polygon, Multipoint, TriangleFan, Triangles, TriangleStrip, or MultiPatch with new ones.
	UpdatePoint	Changes the ith vertex or point to be a copy of the input point.

Classes that implement IPointCollection4

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.
