IncidenceSet

public class HGAtomSet
extends Object
implements HGSortedSet<HGHandle>

A HGAtomSet represents a temporary construction of a set of atoms. Each atom handle is stored in the set. The implementation provides:

• Very fast membership operation.
• Fast addition and removal of elements.
• Long term persistence of the set.
