Field Detail

EMPTY_SET

public static final ByteSets.EmptySet EMPTY_SET

An empty 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 ByteSet singleton(byte 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 ByteSet singleton(Byte 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 ByteSet synchronize(ByteSet 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 ByteSet synchronize(ByteSet 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 ByteSet unmodifiable(ByteSet 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.
