implements IntSortedSet, Serializable, Cloneable

An immutable class representing the empty sorted set and implementing a type-specific set interface.

This class may be useful to implement your own in case you subclass a type-specific sorted set.

Method Detail

remove

public boolean remove(int ok)
Description copied from interface: IntSet
Removes an element from this set.

Note that the corresponding method of the type-specific collection is rem(). This unfortunate situation is caused by the clash with the similarly named index-based method in the List interface.

Specified by:
remove in interface IntSet
Overrides:
remove in class IntSets.EmptySet
See Also:
Collection.remove(Object)

intIterator

@Deprecated
public IntBidirectionalIterator intIterator()
Deprecated. 

Description copied from class: AbstractIntCollection
Delegates to the new covariantly stronger generic method.

Specified by:
intIterator in interface IntCollection
Specified by:
intIterator in interface IntSortedSet
Overrides:
intIterator in class AbstractIntCollection
See Also:
IntCollection.iterator()

iterator

public IntBidirectionalIterator iterator(int from)
Description copied from interface: IntSortedSet
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 IntSortedSet
Parameters:
from - an element to start from.
Returns:
a bidirectional iterator on the element in this set, starting at the given element.

subSet

public IntSortedSet subSet(int from,
                           int to)

comparator

public IntComparator comparator()
Description copied from interface: IntSortedSet

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

Specified by:
subSet in interface IntSortedSet
Specified by:
subSet in interface SortedSet<Integer>
See Also:
SortedSet.subSet(Object,Object)

headSet
