Members

	Name	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.
	ClipEx	Constructs the intersection of this geometry and the specified 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.
	Cut2	Divides a geometry into multiple parts
	Difference	Constructs the geometry containing points from this geometry but not the other geometry.
	GeoNormalizeEx	Shifts longitudes, if need be, into a continuous range of 360 degrees.
	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.
	IsSimpleEx	Determines why a geometry is not simple. Currently only implemented for polygons.
	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.
	TopologyCache	Provides a handle to the TopologyCache.
	Union	Constructs the geometry that is the set-theoretic union of the input geometries.
