All Implemented Interfaces:

com.jme3.export.Savable

public class SixDofJoint
extends PhysicsJoint

From bullet manual:
This generic constraint can emulate a variety of standard constraints, by configuring each of the 6 degrees of freedom (DOF). The first 3 DOF axes are linear axes, which represent translation of rigid bodies, and the latter 3 DOF axes represent the angular motion. Each axis can be either locked, free or limited. On construction of a new btGeneric6DofConstraint, all axis are locked. Afterwards the axis can be reconfigured. Note that several combinations that include free and/or limited angular degrees of freedom are undefined.
