Field Detail

EMPTY_SET

public static final ShortSortedSets.EmptySet EMPTY_SET
An empty sorted set (immutable). It is serializable and cloneable.

The class of this objects represent an abstract empty set that is a subset of a (sorted) type-specific set.

Method Detail

singleton

public static ShortSortedSet singleton(short element)
Returns a type-specific immutable sorted set containing only the specified element. The returned sorted set is serializable and cloneable.

Parameters:
element - the only element of the returned sorted set.
Returns:
a type-specific immutable sorted set containing just element.

singleton

public static ShortSortedSet singleton(short element,
                                       ShortComparator comparator)
Returns a type-specific immutable sorted set containing only the specified element, and using a specified comparator. The returned sorted set is serializable and cloneable.

Parameters:
element - the only element of the returned sorted set.
comparator - the comparator to use in the returned sorted set.
Returns:
a type-specific immutable sorted set containing just element.

singleton

public static ShortSortedSet singleton(Object element)
Returns a type-specific immutable sorted set containing only the specified element. The returned sorted set is serializable and cloneable.

Parameters:
element - the only element of the returned sorted set.
Returns:
a type-specific immutable sorted set containing just element.

singleton

public static ShortSortedSet singleton(Object element,
                                       ShortComparator comparator)
Returns a type-specific immutable sorted set containing only the specified element, and using a specified comparator. The returned sorted set is serializable and cloneable.

Parameters:
element - the only element of the returned sorted set.
comparator - the comparator to use in the returned sorted set.
Returns:
a type-specific immutable sorted set containing just element.

synchronize

public static ShortSortedSet synchronize(ShortSortedSet s)
Returns a synchronized type-specific sorted set backed by the given type-specific sorted set.

Parameters:
s - the sorted set to be wrapped in a synchronized sorted set.
Returns:
a synchronized view of the specified sorted set.

Collections.synchronizedSortedSet(SortedSet)

synchronize

public static ShortSortedSet synchronize(ShortSortedSet s,
                                         Object sync)
Returns a synchronized type-specific sorted set backed by the given type-specific sorted set, using an assigned object to synchronize.

Parameters:
s - the sorted set to be wrapped in a synchronized sorted set.
sync - an object that will be used to synchronize the access to the sorted set.
Returns:
a synchronized view of the specified sorted set.

Collections.synchronizedSortedSet(SortedSet)

unmodifiable

public static ShortSortedSet unmodifiable(ShortSortedSet s)
Returns an unmodifiable type-specific sorted set backed by the given type-specific sorted set.

Parameters:
s - the sorted set to be wrapped in an unmodifiable sorted set.
Returns:
an unmodifiable view of the specified sorted set.
