    • cacheString

      private static String cacheString(char[] charBuf, String[] stringCache, int start, int count)
      Caches short strings, as a flywheel pattern, to reduce GC load. Just for this doc, to prevent leaks.

      Simplistic, and on hash collisions just falls back to creating a new string, vs a full HashMap with Entry list. That saves both having to create objects as hash keys, and running through the entry list, at the expense of some more duplicates.

    • rangeEquals

      static boolean rangeEquals(char[] charBuf, int start, int count, String cached)
      Check if the value of the provided range equals the string.

    • rangeEquals

      boolean rangeEquals(int start, int count, String cached)
