    • internListOf

      public static List<String> internListOf(Object... objects)
      Converts the given objects into a set of potentially cached and interned strings contained within an internal pool of lists. See String.intern().

      The values stored at even number positions will be converted to strings and interned.

      Parameters:
      values - The objects
      Returns:
      An unmodifiable set of strings
      See Also:
    • internMapOf
