All Implemented Interfaces:

Savable, JmeCloneable, java.lang.Cloneable

Direct Known Subclasses:

BoneLink, TorsoLink
```
public abstract class PhysicsLink
extends java.lang.Object
implements JmeCloneable, Savable
```
The abstract base class used by DynamicAnimControl to link pieces of a JME model to their corresponding collision objects in a ragdoll. Subclasses include BoneLink and TorsoLink. The links in each DynamicAnimControl form a hierarchy with the TorsoLink at its root.
This class is shared between JBullet and Native Bullet.
