Constructor Detail

AbstractObject2ShortSortedMap.KeySet

protected AbstractObject2ShortSortedMap.KeySet()
Method Detail

contains

public boolean contains(Object k)
Specified by:
contains in interface Collection<K>
Specified by:
contains in interface Set<K>
Overrides:
contains in class AbstractCollection<K>

size

public int size()
Specified by:
size in interface Collection<K>
Specified by:
size in interface Set<K>
Specified by:
size in class AbstractCollection<K>

clear

public void clear()
Specified by:
clear in interface Collection<K>
Specified by:
clear in interface Set<K>
Overrides:
clear in class AbstractCollection<K>

comparator

public Comparator<? super K> comparator()

first

public K first()

last

public K last()

headSet

public ObjectSortedSet<K> headSet(K to)
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).

See Also:
SortedSet.headSet(Object)

tailSet

public ObjectSortedSet<K> tailSet(K from)
Description copied from interface: ObjectSortedSet
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).

See Also:
SortedSet.tailSet(Object)

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).

See Also:
SortedSet.subSet(Object,Object)

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.

Parameters:
from - an element to start from.
Returns:
a bidirectional iterator on the element in this set, starting at the given element.

iterator

public ObjectBidirectionalIterator<K> iterator()
Description copied from interface: ObjectCollection
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 ObjectCollection<K>
Specified by:
iterator in interface ObjectIterable<K>
Specified by:
iterator in interface ObjectSet<K>
Specified by:
iterator in interface ObjectSortedSet<K>
Specified by:
iterator in interface Iterable<K>
Specified by:
iterator in interface Collection<K>
Specified by:
iterator in interface Set<K>
Specified by:
iterator in class AbstractObjectSortedSet<K>
Returns:
a type-specific iterator on the elements of this collection.
