Class DefaultEnvelope

java.lang.Object

org.gvsig.fmap.geom.generalpath.primitive.DefaultEnvelope

All Implemented Interfaces:

java.lang.Cloneable, org.gvsig.fmap.geom.primitive.Envelope, org.gvsig.tools.persistence.Persistent

Direct Known Subclasses:

Envelope2D, Envelope3D

public abstract class DefaultEnvelope
extends java.lang.Object
implements org.gvsig.fmap.geom.primitive.Envelope, org.gvsig.tools.lang.Cloneable

A minimum bounding box or rectangle. Regardless of dimension, an Envelope can be represented without ambiguity as two direct positions (coordinate points). To encode an Envelope, it is sufficient to encode these two points. This is consistent with all of the data types in this specification, their state is represented by their publicly accessible attributes.
