      • emptySet

        public static ByteSet emptySet()
        Returns an empty set (immutable). It is serializable and cloneable.

        This method provides a typesafe access to EMPTY_SET.

        Returns:
        an empty set (immutable).
      • 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​(java.lang.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,
                                          java.lang.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.
