Special reference component for source frames that also returns the
associated target frame as a hard reference. This ensures that the
reference will be removed if the target frame is removed via the GUI.
Nested Class Summary
Nested classes/interfaces inherited from interface artisynth.core.modelbase.ModelComponent
Appends all hard references for this component to a list.
References are other components, outside of this component's
immediate ancestry, on which this component depends. For
example, an AxialSpring refers to two Point components as
for it's end points. A hard reference is one which
the referring component must have, and which if deleted, implies
that the referring component should be deleted too.
