Class GM_Envelope_Impl

java.lang.Object
  org.deegree_impl.model.geometry.GM_Envelope_Impl

All Implemented Interfaces:

GM_Envelope, java.io.Serializable

Direct Known Subclasses:

LayerBoundingBox_Impl

public class GM_Envelope_Impl

extends java.lang.Object

implements GM_Envelope, java.io.Serializable

a boundingbox as child of a GM_Polygon isn't part of the iso19107 spec but it simplifies the geometry handling within jago

Constructor Summary

GM_Envelope_Impl()
Creates a new GM_Envelope_Impl object.

GM_Envelope_Impl(GM_Position min, GM_Position max)
Creates a new GM_Envelope_Impl object.

Method Summary

java.lang.Object	clone()
boolean	contains(GM_Envelope bb) returns true if all points of the submitted bounding box are within this bounding box
boolean	contains(GM_Position point) returns true if the bounding box conatins the specified GM_Point
GM_Envelope	createIntersection(GM_Envelope bb) returns a new GM_Envelope object representing the intersection of this GM_Envelope with the specified GM_Envelope. * Note: If there is no intersection at all GM_Envelope will be null.
boolean	equals(java.lang.Object other) checks if this point is completly equal to the submitted geometry
GM_Envelope	getBuffer(double b) creates a new envelope
double	getHeight() returns the height of bounding box
GM_Position	getMax() returns the maximum coordinates of bounding box
GM_Position	getMin() returns the minimum coordinates of bounding box
double	getWidth() returns the width of bounding box
boolean	intersects(GM_Envelope bb) returns true if this envelope and the submitted intersects
GM_Envelope	merge(GM_Envelope envelope) merges two GM_Envelops and returns the minimum envelope containing both.
