Field Details

EMPTY_SET

public static final IntSortedSets.EmptySet EMPTY_SET

An empty sorted set (immutable). It is serializable and cloneable.

Method Details

emptySet

public static IntSortedSet emptySet()

Returns an empty sorted set (immutable). It is serializable and cloneable.

This method provides a typesafe access to EMPTY_SET.

Returns:

an empty sorted set (immutable).

singleton

public static IntSortedSet singleton(int 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 IntSortedSet singleton(int element,
 IntComparator 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 IntSortedSet 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 IntSortedSet singleton(Object element,
 IntComparator 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 IntSortedSet synchronize(IntSortedSet 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 IntSortedSet synchronize(IntSortedSet 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 IntSortedSet unmodifiable(IntSortedSet 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.
