    • get

      public byte get(int index)
      Read the byte at getArray()[getOffset() + index] and return it as a byte, similar to TruffleString.ReadByteNode. Consider using TruffleString.ReadByteNode (and TruffleString.MaterializeNode before) instead if not needing the byte[] for other purposes, as that will avoid extra copying if the string is stored in native memory.
