Class OctagonalEnvelope

java.lang.Object

com.vividsolutions.jts.geom.OctagonalEnvelope

public class OctagonalEnvelope
extends Object

A bounding container for a Geometry which is in the shape of a general octagon. The OctagonalEnvelope of a geometric object is a geometry which is a tight bound along the (up to) four extremal rectilinear parallels and along the (up to) four extremal diagonal parallels. Depending on the shape of the contained geometry, the octagon may be degenerate to any extreme (e.g. it may be a rectangle, a line, or a point).
