Class ObjectSortedSets.EmptySet<K>

    • Method Detail

      • iterator

        public ObjectBidirectionalIterator<K> iterator​(K from)
        Description copied from interface: ObjectSortedSet
        Returns a type-specific BidirectionalIterator on the elements in this set, starting from a given element of the domain (optional operation).

        This method returns a type-specific bidirectional iterator with given starting point. The starting point is any element comparable to the elements of this set (even if it does not actually belong to the set). The next element of the returned iterator is the least element of the set that is greater than the starting point (if there are no elements greater than the starting point, hasNext() will return false). The previous element of the returned iterator is the greatest element of the set that is smaller than or equal to the starting point (if there are no elements smaller than or equal to the starting point, hasPrevious() will return false).

        Note that passing the last element of the set as starting point and calling previous() you can traverse the entire set in reverse order.

        Specified by:
        iterator in interface ObjectSortedSet<K>
        Parameters:
        from - an element to start from.
        Returns:
        a bidirectional iterator on the element in this set, starting at the given element.
      • subSet

        public ObjectSortedSet<K> subSet​(K from,
                                         K to)
        Description copied from interface: ObjectSortedSet
        Returns a view of the portion of this sorted set whose elements range from fromElement, inclusive, to toElement, exclusive.

        Note that this specification strengthens the one given in SortedSet.subSet(Object,Object).

      • headSet

        public ObjectSortedSet<K> headSet​(K from)
        Description copied from interface: ObjectSortedSet
        Returns a view of the portion of this sorted set whose elements are strictly less than toElement.

        Note that this specification strengthens the one given in SortedSet.headSet(Object).

        public ObjectSortedSet<K> tailSet​(K to)
        Description copied from interface: ObjectSortedSet
        Returns a view of the portion of this sorted set whose elements are greater than or equal to fromElement.
