Method Detail

singleton

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

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

singleton

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

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

synchronize

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

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

Collections.synchronizedSet(Set)

synchronize

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

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

Collections.synchronizedSet(Set)

unmodifiable

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

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