Interface SurfaceBoundary

All Superinterfaces:

Boundary, Geometry, PrimitiveBoundary, java.io.Serializable

All Known Implementing Classes:

SurfaceBoundaryImpl

public interface SurfaceBoundary
extends PrimitiveBoundary

Defining the boundary of a surface. The surface boundary is defined as ring surrounding the exterior boundary of the surface and the rings surrounding each interior ring of the surface.

A SurfaceBoundary consists of some number of Rings, corresponding to the various components of its boundary. In the normal 2D case, one of these rings is distinguished as being the exterior boundary. In a general manifold this is not always possible, in which case all boundaries shall be listed as interior boundaries, and the exterior will be empty.
