Method Summary

Modifier and Type	Method and Description
void	add(java.lang.Object e) Adds obj to this.
void	clear() implemented, but *very* inefficient.
ArraySparseSet	clone() Clones the current FlowSet.
boolean	contains(java.lang.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.
java.lang.Object	emptySet() implemented, but inefficient.
boolean	equals(java.lang.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(java.lang.Object obj) Removes obj from this.
int	size() Returns the size of the current FlowSet.
java.util.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.
