ITopologicalOperator6 Interface

Product Availability

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

Members

	Name	Description
	ConstructUnionEx	Defines this geometry to be the union of the inputs, with the option for non-planary result.
	DifferenceEx	defined for (multi)points and polylines.
	IntersectEx	Constructs the set-theoretic intersection of the inputs in the specified result dimension, , with the option for non-planary result.
	IntersectMultidimensionEx	Constructs the set-theoretic intersection of the inputs. The results are returned in a geometry bag with one element per result dimension.
	SimplifyAsFeature	Simplifies the geometry using the rules appropriate for this feature.
	SymmetricDifferenceEx	defined for (multi)points and polylines.
	UnionEx	Constructs the set-theoretic union of the inputs, with the option for non-planary result.

Classes that implement ITopologicalOperator6

Classes	Description
Multipoint	An ordered collection of points; optionally has measure, height and ID attributes.
Point	A two dimensional point, optionally with 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.

Remarks

ITopologicalOperator6 methods must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon. To use this interface with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, Bezier Curve), paths or rings, they must be wrapped into high-level geometry types.
