Constructor Detail

XYZ

public XYZ()

Creates a new instance of XYZ

XYZ

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

Create a new XYZ coordinate

Parameters:

x - The X component

y - The Y component

z - Th Z component

Method Detail

x

public double x()

Get the X component

Returns:

The X component

y

public double y()

Get the Y component

Returns:

The Y component

z

public double z()

Get the Z component

Returns:

The Z component

hashCode

public int hashCode()

Provide a hashcode for this XYZ based on the values contained. This is necessary to meet the contract for the Object.hashcode() method which requires that if object1.equals(object2) their hashcodes must also be equal.

Overrides:

hashCode in class java.lang.Object

Returns:

hashcode

equals

public boolean equals(java.lang.Object obj)

Compare this XYZ with another Object

Overrides:

equals in class java.lang.Object

Parameters:

obj - - the Objecty to compare to.

Returns:

true if obj is another XYZ containing the same values. They are not necessarily the same object.
