public static class DoubleSortedSets.EmptySet
extends DoubleSets.EmptySet
implements DoubleSortedSet, 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(double ok)

Description copied from interface: DoubleSet

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 DoubleSet

Overrides:

remove in class DoubleSets.EmptySet

See Also:

Collection.remove(Object)

doubleIterator

@Deprecated
public DoubleBidirectionalIterator doubleIterator()

Deprecated.

Description copied from class: AbstractDoubleCollection

Delegates to the new covariantly stronger generic method.

Specified by:

doubleIterator in interface DoubleCollection

Specified by:

doubleIterator in interface DoubleSortedSet

Overrides:

doubleIterator in class AbstractDoubleCollection

See Also:

DoubleCollection.iterator()

iterator

public DoubleBidirectionalIterator iterator(double from)

Description copied from interface: DoubleSortedSet

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 DoubleSortedSet

Parameters:

from - an element to start from.

Returns:

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