                 Collection<? extends E> coll)

  Called when a collection is to be added to the composite.

  Parameters:

  composite - the CompositeSet being changed

  sets - all of the Set instances in this CompositeSet

  coll - the collection being added

  Returns:

• resolveCollision

  void resolveCollision(CompositeSet<E> comp,
                        Set<E> existing,
                        Set<E> added,
                        Collection<E> intersects)
