ITopologicalOperator2 Interface

Provides access to members that extend the ITopologicalOperator interface. Note: the ITopologicalOperator2 interface has been superseded byITopologicalOperator5. Please consider using the more recent version.

	All Properties Methods Inherited Non-inherited	Description
	Boundary	The boundary of this geometry. A polygon's boundary is a polyline. A polyline's boundary is a multipoint. A point or multipoint's boundary is an empty point or multipoint.
	Buffer	Constructs a polygon that is the locus of points at a distance less than or equal to a specified distance from this geometry.
	Clip	Constructs the intersection of this geometry and the specified envelope.
	ClipDense	Constructs the intersection of this geometry and the specified envelope; densifies lines in output contributed by the clipping envelope.
	ClipToDomain	Clips the geometry to the domain of the spatial reference. Useful for ensuring that buffers can be fit within the spatial domain of the feature class to which they are being added.
	ConstructBuffers	Constructs a set of buffers at various distances. More efficient than calling Buffer repeatedly on the same geometry. This method is intended for internal use only.
	ConstructUnion	Defines this geometry to be the union of the inputs. More efficient for unioning multiple geometries than calling Union repeatedly.
	ConvexHull	Constructs the convex hull of this geometry.
	Cut	Splits this geometry into a part left of the cutting polyline, and a part right of it.
	Difference	Constructs the geometry containing points from this geometry but not the other geometry.
	Intersect	Constructs the geometry that is the set-theoretic intersection of the input geometries. Use different resultDimension values to generate results of different dimensions.
	IntersectMultidimension	Constructs the set-theoretic intersection of the inputs. The results are returned in a geometry bag with one element per result dimension.
	IsKnownSimple	Indicates whether this geometry is known (or assumed) to be topologically correct.
	IsKnownSimple	Indicates whether this geometry is known (or assumed) to be topologically correct.
	IsSimple	Indicates whether this geometry is known (or assumed) to be topologically correct, after explicitly determining this if the geometry is not already known (or assumed) to be simple.
	QueryClipped	Redefines clippedGeometry to be the intersection of this geometry and the clipping envelope.
	QueryClippedDense	Redefines clippedGeometry to be the intersection of this geometry and the clipping envelope; densifies lines in the output contributed by the clipping envelope.
	Simplify	Makes this geometry topologically correct.
	SymmetricDifference	Constructs the geometry that contains points from either but not both input geometries.
	Union	Constructs the geometry that is the set-theoretic union of the input geometries.

CoClasses that implement ITopologicalOperator2

Remarks

ITopologicalOperator2 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.

For multipatch geometries, generally the footprint or envelope is used.
