    • containsAll

      public boolean containsAll(Collection c)
      Returns true if this collection contains all of the elements in the specified collection.

      This implementation iterates over the specified collection, checking each element returned by the iterator in turn to see if it's contained in this collection. If all elements are so contained true is returned, otherwise false.

      Returns:
      a shallow copy of this set.

    • getSCOHashSet

      public HashSet getSCOHashSet()
      Returns set of the persistence-capable instances associated with this Set.

      Set of the persistence-capable instances.

    • setSCOHashSet

      public void setSCOHashSet(Collection coll)
      Replace the set of the persistence-capable instances associated with this EJBHashSet. There is no need to check transaction as it has already been checked in this case.

    • iterator
