Class Coordinate

java.lang.Object

org.openstreetmap.josm.data.coor.Coordinate

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

EastNorth, LatLon

abstract class Coordinate
extends java.lang.Object
implements java.io.Serializable

Base class of points of both coordinate systems. The variables are default package protected to allow routines in the data package to access them directly. As the class itself is package protected too, it is not visible outside of the data package. Routines there should only use LatLon or EastNorth.

Since:

6162

y - Y coordinate of the point.

Method Detail

getX

public double getX()

getY

public double getY()

distance

protected final double distance(Coordinate coor)

Returns the euclidean distance from this Coordinate to a specified Coordinate.

Parameters:

coor - the specified coordinate to be measured against this Coordinate

Returns:

the euclidean distance from this Coordinate to a specified Coordinate

Since:

6166

distance

public final double distance(double px,
                             double py)

Returns the euclidean distance from this Coordinate to a specified coordinate.

Parameters:

px - the X coordinate of the specified point to be measured against this Coordinate

py - the Y coordinate of the specified point to be measured against this Coordinate

Returns:

the euclidean distance from this Coordinate to a specified coordinate

Since:

6166

distanceSq

protected final double distanceSq(Coordinate coor)

Returns the square of the euclidean distance from this Coordinate to a specified Coordinate.

Parameters:

coor - the specified coordinate to be measured against this Coordinate

Returns:

the square of the euclidean distance from this Coordinate to a specified Coordinate

Since:

6166

distanceSq

public final double distanceSq(double px,
                               double py)
