Interface DSet

  • All Superinterfaces:
    java.util.Collection, DCollection, java.lang.Iterable, java.util.Set
    All Known Implementing Classes:
    RasSet
    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.

      • union

        DSet union​(DSet otherSet)
        Create a new DSet object that is the set union of this DSet object and the set referenced by otherSet,
        not yet available in RasDaMan.
        Parameters:
        otherSet - The other set to be used in the union operation.
        Returns:
        A newly created DSet instance that contains the union of the two sets.

      • intersection

        DSet intersection​(DSet otherSet)
        Create a new DSet object that is the set intersection of this DSet object and the set referenced by otherSet,
        not yet available in RasDaMan.
        Parameters:
        otherSet - The other set to be used in the intersection operation.
        Returns:
        A newly created DSet instance that contains the intersection of the two sets.

      • difference

        DSet difference​(DSet otherSet)
        Create a new DSet object that contains the elements of this collection minus the elements in otherSet,
        not yet available in RasDaMan.
        Parameters:
        otherSet - A set containing elements that should not be in the result set.
        Returns:
        A newly created DSet instance that contains the elements of this set minus those elements in otherSet.

      • subsetOf

        boolean subsetOf​(DSet otherSet)
        Determine whether this set is a subset of the set referenced by otherSet,
        not yet available in RasDaMan.
        Parameters:
        otherSet - Another set.
        Returns:
        True if this set is a subset of the set referenced by otherSet, otherwise false.

      • properSubsetOf

        boolean properSubsetOf​(DSet otherSet)
