Interface DSet

All Superinterfaces:: java.util.Collection, DCollection, java.lang.Iterable, java.util.Set

public interface DSet
extends DCollection, java.util.Set

The ODMG Set collection interface. A DSet object is an unordered collection that does not support multiple elements with the same value. An implementation typically is very efficient at determining whether the collection contains a particular value.

All of the operations defined by the JavaSoft Set interface are supported by an ODMG implementation of DSet, the exception UnsupportedOperationException is not thrown when a call is made to any of the Set methods.

Version:: ODMG 3.0

Method Summary

DSet difference(DSet otherSet)
          Create a new DSet object that contains the elements of this collection minus the elements in otherSet.

DSet intersection(DSet otherSet)
          Create a new DSet object that is the set intersection of this DSet object and the set referenced by otherSet.

boolean properSubsetOf(DSet otherSet)
          Determine whether this set is a proper subset of the set referenced by otherSet.

boolean properSupersetOf(DSet otherSet)
          Determine whether this set is a proper superset of the set referenced by otherSet.

boolean subsetOf(DSet otherSet)
          Determine whether this set is a subset of the set referenced by otherSet.

boolean supersetOf(DSet otherSet)
          Determine whether this set is a superset of the set referenced by otherSet.

DSet union(DSet otherSet)
          Create a new DSet object that is the set union of this DSet object and the set referenced by otherSet.
