      public class RowKeySetTreeImpl
      extends RowKeySet
      implements Serializable

  Implements a collection of rowKeys from a TreeModel. The methods on this class are optimized such that it is possible to add/remove all the rowkeys in a subtree in constant time.

  The generic type E is the type of a rowKey.

      Inverts this Set. Every element that is in this Set is removed, and every element that is not in this Set is added to this Set.
