Method Summary
 void add(Object e)
          Adds obj to this.
 void clear()
          implemented, but *very* inefficient.
 ArraySparseSet clone()
          Clones the current FlowSet.
 boolean contains(Object obj)
          Deprecated. This method uses linear-time lookup. For better performance, consider using a HashSet instead, if you require this operation.
 void copy(FlowSet destFlow)
          Copies the current FlowSet into dest.
 void difference(FlowSet otherFlow, FlowSet destFlow)
          Returns the set difference (this intersect ~other) of this FlowSet and other, putting result into dest.
 Object emptySet()
          implemented, but inefficient.
 boolean equals(Object otherFlow)
           
 void intersection(FlowSet otherFlow, FlowSet destFlow)
          Returns the intersection (meet) of this FlowSet and other, putting result into dest.
 boolean isEmpty()
          Returns true if this FlowSet is the empty set.
 void remove(Object obj)
          Removes obj from this.
 int size()
          Returns the size of the current FlowSet.
 List toList()
          Returns a unbacked list of elements in this set.
 void union(FlowSet otherFlow, FlowSet destFlow)
          Returns the union (join) of this FlowSet and other, putting result into dest.
