Package org.bukkit

Class Location

java.lang.Object

org.bukkit.Location

All Implemented Interfaces:

Cloneable, ConfigurationSerializable

public class Location
extends Object
implements Cloneable, ConfigurationSerializable

Represents a 3-dimensional position in a world.
No constraints are placed on any angular values other than that they be specified in degrees. This means that negative angles or angles of greater magnitude than 360 are valid, but may be normalized to any other equivalent representation by the implementation.
