org.openstreetmap.josm.data.ProjectionBounds

public class ProjectionBounds
extends java.lang.Object

This is a simple data class for "rectangular" areas of the world, given in east/north min/max values.

Field Summary

Constructor Summary

Constructors

Constructor and Description
ProjectionBounds(double minEast, double minNorth, double maxEast, double maxNorth) Construct bounds out of two points.
ProjectionBounds(EastNorth p) Construct bounds out of a single point.
ProjectionBounds(EastNorth center, double east, double north) Construct bounds out of a center point and east/north dimensions.
ProjectionBounds(EastNorth min, EastNorth max) Construct bounds out of two points.

Method Summary

Modifier and Type	Method and Description
boolean	contains(EastNorth en) Check, if a point is within the bounds.
void	extend(EastNorth e) Extends bounds to include point e.
EastNorth	getCenter() Returns the center east/north.
EastNorth	getMax() Returns the max east/north.
EastNorth	getMin() Returns the min east/north.
boolean	hasExtend() Determines if the bounds area is not null
boolean	intersects(ProjectionBounds b) The two bounds intersect? Compared to java Shape.intersects, if does not use the interior but the closure.

getCenter

public EastNorth getCenter()

Returns the center east/north.

Returns:

the center east/north

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

intersects

public boolean intersects(ProjectionBounds b)

getMax

public EastNorth getMax()

Returns the max east/north.

Returns:

the max east/north

hasExtend

public boolean hasExtend()

Determines if the bounds area is not null

Returns:

true if the area is not null
