Interface Boundary

All Superinterfaces:

Complex, Geometry, TransfiniteSet

All Known Subinterfaces:

ComplexBoundary, CurveBoundary, PrimitiveBoundary, SolidBoundary, SurfaceBoundary

@UML(identifier="GM_Boundary",
     specification=ISO_19107)
public interface Boundary
extends Complex

The abstract root data type for all the data types used to represent the boundary of geometric objects. Any subclass of Geometry will use a subclass of Boundary to represent its boundary through the operation Geometry.getBoundary(). By the nature of geometry, boundary objects are cycles.

Since:

GeoAPI 1.0
