    - #### expand

          public static java.nio.ByteBuffer expand​(java.nio.ByteBuffer in,
                                                   int newSize)

      Expands buffer to the given size unless it is already as big or bigger. Buffers are assumed to be in 'write to' mode since there would be no need to expand a buffer while it was in 'read from' mode.
      Parameters:
        `in` - Buffer to expand
        `newSize` - The size t which the buffer should be expanded
      Returns:
        The expanded buffer with any data from the input buffer copied in to it or the original buffer if there was no need for expansion

    - #### cleanDirectBuffer

          public static void cleanDirectBuffer​(java.nio.ByteBuffer buf)
