public static class ByteSortedSets.EmptySet
extends ByteSets.EmptySet
implements ByteSortedSet, 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(byte ok)

Description copied from interface: ByteSet

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 ByteSet

Overrides:

remove in class ByteSets.EmptySet

See Also:

Collection.remove(Object)

byteIterator

@Deprecated
public ByteBidirectionalIterator byteIterator()

Deprecated.

Description copied from class: AbstractByteCollection

Delegates to the new covariantly stronger generic method.

Specified by:

byteIterator in interface ByteCollection

Specified by:

byteIterator in interface ByteSortedSet

Overrides:

byteIterator in class AbstractByteCollection

See Also:

ByteCollection.iterator()

iterator

public ByteBidirectionalIterator iterator(byte from)

Description copied from interface: ByteSortedSet

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 ByteSortedSet

Parameters:

from - an element to start from.

Returns:

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

subSet

public ByteSortedSet subSet(byte from,
                   byte to)

comparator

public ByteComparator comparator()

Description copied from interface: ByteSortedSet

Returns the comparator associated with this sorted set, or null if it uses its elements' natural ordering.

Note that this specification strengthens the one given in SortedSet.comparator().
