  • Field Details

    • EMPTY_SET

      public static final ByteSets.EmptySet EMPTY_SET
      An empty set (immutable). It is serializable and cloneable.

  • Method Details

    • 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(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.

    • 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.

    • 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.

    • fromTo

      public static ByteSet fromTo(byte from, byte to)
      Returns an unmodifiable type-specific set containing elements in the given range.
      Parameters:
      from - the starting element (lower bound) of the set (inclusive).
      to - the ending element (upper bound) of the set (exclusive).
      Returns:
      an unmodifiable set containing the elements in the given range.

    • from

      public static ByteSet from(byte from)
      Returns an unmodifiable type-specific set containing elements greater than or equal to a given element.
      Parameters:
      from - the starting element (lower bound) of the set (inclusive).
      Returns:
      an unmodifiable set containing the elements greater than or equal to from.

    • to

      public static ByteSet to(byte to)
      Returns an unmodifiable type-specific set containing elements smaller than a given element.
      Parameters:
      to - the ending element (upper bound) of the set (exclusive).
      Returns:
      an unmodifiable set containing the elements smaller than to.
