getBoundary method

Geometry getBoundary()
override

Returns the boundary, or an empty geometry of appropriate dimension if this Geometry is empty. (In the case of zero-dimensional geometries, ' an empty GeometryCollection is returned.) For a discussion of this function, see the OpenGIS Simple Features Specification. As stated in SFS Section 2.1.13.1, "the boundary of a Geometry is a set of Geometries of the next lower dimension."

@return the closure of the combinatorial boundary of this Geometry

Implementation

Geometry getBoundary() {
  Geometry.checkNotGeometryCollection(this);
  Assert.shouldNeverReachHere();
  throw StateError("Should never reach here");
}
