All known Subclasses: org.apache.ojb.odmg.collections.DSetImpl,
| DSet | | public interface DSet extends DCollection,java.util.Set(Code) | | 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.

| Method Summary | |
| public DSet | difference(DSet otherSet)
Create a new DSet object that contains the elements of this
collection minus the elements in otherSet. | | public DSet | intersection(DSet otherSet)
Create a new DSet object that is the set intersection of this
DSet object and the set referenced by otherSet. | | public boolean | properSubsetOf(DSet otherSet)
Determine whether this set is a proper subset of the set referenced by
otherSet.
Parameters:
otherSet - Another set. | | public boolean | properSupersetOf(DSet otherSet)
Determine whether this set is a proper superset of the set referenced by
otherSet.
Parameters:
otherSet - Another set. | | public boolean | subsetOf(DSet otherSet)
Determine whether this set is a subset of the set referenced by otherSet.
Parameters:
otherSet - Another set. | | public boolean | supersetOf(DSet otherSet)
Determine whether this set is a superset of the set referenced by otherSet.
Parameters:
otherSet - Another set. | | public DSet | union(DSet otherSet)
Create a new DSet object that is the set union of this
DSet object and the set referenced by otherSet. |
| difference | | public DSet difference(DSet otherSet)(Code) | | Create a new DSet object that contains the elements of this
collection minus the elements in otherSet.
Parameters:
otherSet - A set containing elements that should not be in the result set. A newly created DSet instance that contains the elementsof this set minus those elements in otherSet. |
| intersection | | public DSet intersection(DSet otherSet)(Code) | | Create a new DSet object that is the set intersection of this
DSet object and the set referenced by otherSet.
Parameters:
otherSet - The other set to be used in the intersection operation. A newly created DSet instance that contains theintersection of the two sets. |
| properSubsetOf | | public boolean properSubsetOf(DSet otherSet)(Code) | | Determine whether this set is a proper subset of the set referenced by
otherSet.
Parameters:
otherSet - Another set. True if this set is a proper subset of the set referenced byotherSet, otherwise false. |
| properSupersetOf | | public boolean properSupersetOf(DSet otherSet)(Code) | | Determine whether this set is a proper superset of the set referenced by
otherSet.
Parameters:
otherSet - Another set. True if this set is a proper superset of the set referenced byotherSet, otherwise false. |
| subsetOf | | public boolean subsetOf(DSet otherSet)(Code) | | Determine whether this set is a subset of the set referenced by otherSet.
Parameters:
otherSet - Another set. True if this set is a subset of the set referenced by otherSet,otherwise false. |
| supersetOf | | public boolean supersetOf(DSet otherSet)(Code) | | Determine whether this set is a superset of the set referenced by otherSet.
Parameters:
otherSet - Another set. True if this set is a superset of the set referenced by otherSet,otherwise false. |
| union | | public DSet union(DSet otherSet)(Code) | | Create a new DSet object that is the set union of this
DSet object and the set referenced by otherSet.
Parameters:
otherSet - The other set to be used in the union operation. A newly created DSet instance that contains the union of the two sets. |
