Vector (Bukkit 1.7.2-R0.3 API)

java.lang.Object
- org.bukkit.util.Vector

All Implemented Interfaces:

Cloneable, ConfigurationSerializable

Direct Known Subclasses:

BlockVector
```
public class Vector
extends Object
implements Cloneable, ConfigurationSerializable
```
Represents a mutable vector. Because the components of Vectors are mutable, storing Vectors long term may be dangerous if passing code modifies the Vector later. If you want to keep around a Vector, it may be wise to call clone() in order to get a copy.
