headSet

public ReferenceSortedSet<K> headSet(K to)

Description copied from interface: ReferenceSortedSet

Returns a view of the portion of this sorted set whose elements are strictly less than toElement.

Specified by:

See Also:

• SortedSet.headSet(Object)

tailSet

public ReferenceSortedSet<K> tailSet(K from)

Description copied from interface: ReferenceSortedSet

Returns a view of the portion of this sorted set whose elements are greater than or equal to fromElement.

Specified by:

tailSet in interface ReferenceSortedSet<K>

Specified by:

iterator

public ObjectBidirectionalIterator<K> iterator()

Description copied from interface: ReferenceCollection

Returns a type-specific iterator on the elements of this collection.

Specified by:

iterator in interface Collection<K>

Specified by:

iterator in interface Iterable<K>

Specified by:

iterator in interface ObjectBidirectionalIterable<K>

Specified by:

Specified by:

iterator in interface ReferenceSortedSet<K>

Specified by:

• Iterable.iterator()

iterator

public ObjectBidirectionalIterator<K> iterator(K from)

Description copied from interface: ReferenceSortedSet

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 ReferenceSortedSet<K>

Parameters:

from - an element to start from.

Returns:

a bidirectional iterator on the element in this set, starting at the given element.
