Method Detail

singleton

public static DoubleSet singleton(double 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 DoubleSet 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 DoubleSet synchronize(DoubleSet 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 DoubleSet synchronize(DoubleSet 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.
