Enclosing class:

FloatSortedSets

public static class FloatSortedSets.EmptySet
extends FloatSets.EmptySet
implements FloatSortedSet, 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(float ok)

Description copied from interface: FloatSet

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 FloatSet

Overrides:

remove in class FloatSets.EmptySet

See Also:

Collection.remove(Object)

floatIterator

@Deprecated
public FloatBidirectionalIterator floatIterator()

Deprecated.

Description copied from class: AbstractFloatCollection

Delegates to the new covariantly stronger generic method.

Specified by:

floatIterator in interface FloatCollection

Specified by:

floatIterator in interface FloatSortedSet

Overrides:

floatIterator in class AbstractFloatCollection

See Also:

FloatCollection.iterator()

iterator

public FloatBidirectionalIterator iterator(float from)

Description copied from interface: FloatSortedSet

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 FloatSortedSet

Parameters:

from - an element to start from.

Returns:

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