singleton
public static DoubleSortedSet singleton(double 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 DoubleSortedSet singleton(double element, DoubleComparator 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 DoubleSortedSet singleton(java.lang.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 DoubleSortedSet singleton(java.lang.Object element, DoubleComparator 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 DoubleSortedSet synchronize(DoubleSortedSet 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.

synchronize
public static DoubleSortedSet synchronize(DoubleSortedSet s, java.lang.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.

unmodifiable
public static DoubleSortedSet unmodifiable(DoubleSortedSet s)
Returns an unmodifiable type-specific sorted set backed by the given type-specific sorted set.- Parameters:
s
