Enclosing class:

CharSortedSets

public static class CharSortedSets.EmptySet
extends CharSets.EmptySet
implements CharSortedSet, 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

rem

public boolean rem(char ok)

Description copied from interface: CharCollection

Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().

Specified by:

rem in interface CharCollection

Overrides:

rem in class CharCollections.EmptyCollection

See Also:

Collection.remove(Object)

charIterator

@Deprecated
public CharBidirectionalIterator charIterator()

Deprecated.

Description copied from class: AbstractCharCollection

Delegates to the new covariantly stronger generic method.

Specified by:

charIterator in interface CharCollection

Specified by:

charIterator in interface CharSortedSet

Overrides:

charIterator in class AbstractCharCollection

See Also:

CharCollection.iterator()

iterator

public CharBidirectionalIterator iterator(char from)

Description copied from interface: CharSortedSet

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 CharSortedSet

Parameters:

from - an element to start from.

Returns:

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