      an empty set (immutable).
    • 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(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.
    • 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.

    • 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.

    • 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.
