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.
