Class BoundaryOp

Hierarchy: Object , BoundaryOp

public class BoundaryOp

Computes the boundary of a Geometry. Allows specifying the BoundaryNodeRule to be used. This operation will always return a Geometry of the appropriate dimension for the boundary (even if the input geometry is empty). The boundary of zero-dimensional geometries (Points) is always the empty GeometryCollection.
