public Point3D(double x,
               double y,
               double z)

Initializes a newly created Point3D instance with the values specified.

Parameters:

x - the X coordinate of this Point3D in coordinate system units

y - the Y coordinate of this Point3D in coordinate system units

z - the Z coordinate, elevation or altitude of this Point3D in meters

Point3D

public Point3D(double x,
               double y)

Initializes a newly created Point3D instance with the values specified and 0 (zero) for the Z-coordinate.

Parameters:

Method Detail

clone

public Object clone()

Creates and returns a copy of this Point3D instance.

Overrides:

clone in class Object

Returns:

a copy of this Point3D instance

equals

public boolean equals(Object obj)

Compares this Point3D object to the specified object. The result is true if and only if the argument is not null and is a Point3D object that represents the same position as this object.

Overrides:

equals in class Object

Parameters:

obj - the object to compare this Point3D object against

Returns:

true if the Point3D objects are equal; false otherwise.

equals

public boolean equals(Point3D pt)

Compares this Point3D object to the specified Point3D object. The result is true if and only if the argument is not null and represents the same position as this object.

Parameters:

pt - the Point3D object to compare this Point3D instance against

Returns:

true if the Point3D objects are equal; false otherwise.

hashCode

public int hashCode()

Returns the hash code for this Point3D instance.

Overrides:

hashCode in class Object

Returns:

a hash code for this Point3D instance

toString

public String toString()

Returns a string representation of this Point3D instance. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.

Overrides:

toString in class Object

Returns:

a string representation of this Point3D object
