Interface GM_Envelope

All Known Subinterfaces:

LayerBoundingBox

All Known Implementing Classes:

GM_Envelope_Impl, LayerBoundingBox_Impl

public interface GM_Envelope

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

Method Summary

boolean	contains(GM_Envelope bb) returns true if all positions of the submitted bounding box are within this bounding box
boolean	contains(GM_Position position) returns true if the bounding box contains the submitted position
GM_Envelope	createIntersection(GM_Envelope bb) returns a new GM_Envelope object representing the intersection of this GM_Envelope with the specified GM_Envelope.
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 intersects the submitted envelope
GM_Envelope	merge(GM_Envelope envelope) merges two GM_Envelops and returns the minimum envelope containing both.
