Method Detail

comparator

public java.util.Comparator<? super K> comparator()
Specified by:
comparator in interface java.util.SortedSet<K>

subSet

public ReferenceSortedSet<K> subSet(K from,
                                    K to)
Description copied from interface: ReferenceSortedSet
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).

Specified by:
subSet in interface ReferenceSortedSet<K>
Specified by:
subSet in interface java.util.SortedSet<K>
See Also:
SortedSet.subSet(Object,Object)

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.

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

Specified by:
headSet in interface ReferenceSortedSet<K>
Specified by:
headSet in interface java.util.SortedSet<K>
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.

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

Specified by:
tailSet in interface ReferenceSortedSet<K>
Specified by:
tailSet in interface java.util.SortedSet<K>
See Also:
SortedSet.tailSet(Object)

iterator

public ObjectBidirectionalIterator<K> iterator()
Description copied from interface: ReferenceCollection
Returns a type-specific iterator on the elements of this collection.

Note that this specification strengthens the one given in Iterable.iterator(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends Collection.

Specified by:
iterator in interface ObjectIterable<K>
Specified by:
iterator in interface ReferenceCollection<K>
Specified by:
iterator in interface ReferenceSet<K>
Specified by:
iterator in interface ReferenceSortedSet<K>
Specified by:
iterator in interface java.lang.Iterable<K>
Specified by:
iterator in interface java.util.Collection<K>
Specified by:
iterator in interface java.util.Set<K>
Overrides:
iterator in class ReferenceCollections.UnmodifiableCollection<K>
Returns:
a type-specific iterator on the elements of this collection.

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.

objectIterator

@Deprecated
public ObjectBidirectionalIterator<K> objectIterator()
Deprecated. 

Description copied from interface: ReferenceCollection
Returns a type-specific iterator on this elements of this collection.

Specified by:
objectIterator in interface ReferenceCollection<K>
Specified by:
objectIterator in interface ReferenceSortedSet<K>
Overrides:
objectIterator in class ReferenceCollections.UnmodifiableCollection<K>

ReferenceCollection.iterator()

first

public K first()
Specified by:
first in interface java.util.SortedSet<K>

last

public K last()
Specified by:
last in interface java.util.SortedSet<K>
