- - ### Methods Detail

    - #### public NavigableSet asChecked(Class type)

      Creates a checked view of a NavigableSet.

      Parameters:
      Since:
        5.0.0
      See Also:
        Collections#checkedNavigableSet

    - #### public NavigableSet asReversed()

      Creates a reverse order view of the set. The order of original list will not change.

          TreeSet navSet = [2, 4, 1, 3]  // natural order is sorted
          assert navSet.asReversed() == [4, 3, 2, 1] as Set

      Returns:
        the reversed view NavigableSet
      Since:
        4.0.11

    - #### public NavigableSet asSynchronized()

      Creates a synchronized view of a NavigableSet.

      Returns:
        a synchronized NavigableSet
      Since:
        5.0.0
      See Also:
        Collections#synchronizedNavigableSet(java.util.NavigableSet)

    - #### public NavigableSet asUnmodifiable()

      Creates an unmodifiable view of a NavigableSet.

      Returns:
        an unmodifiable view of the NavigableSet
      Since:
        5.0.0
      See Also:
        Collections#unmodifiableNavigableSet(java.util.NavigableSet)
        List#asUnmodifiable()

    - #### public NavigableSet reverseEach(Closure closure)

      Iterate over each element of the set in reverse order.

          TreeSet navSet = [2, 4, 1, 3]  // natural order is sorted
          List result = []
          navSet.reverseEach { result << it }
          assert result == [4, 3, 2, 1]

      Parameters:
        `closure` - a closure to which each item is passed.
      Returns:
        the original NavigableSet
      Since:
        4.0.11
