 |
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. |
|
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. |
|
Union | Constructs the geometry that is the set-theoretic union of the input geometries. |
Inherited Interfaces
| Interfaces | Description |
|---|---|
| ITopologicalOperator4 | Provides additional information on non-simple geometries. |
| ITopologicalOperator3 | Provides additional information on non-simple geometries. |
| ITopologicalOperator2 | Provides access to members that extend the ITopologicalOperator interface. |
| ITopologicalOperator | Provides access to members for constructing new geometries based upon topological relationships between existing geometries. |
CoClasses that implement ITopologicalOperator5
| CoClasses and Classes | Description |
|---|---|
| Polyline | An ordered collection of paths; optionally has measure, height and ID attributes. |
Remarks
ITopologicalOperator5 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.
