  #compact
    copies data from the current position to the beginning of the buffer
  #clear
    clears the buffer
  #position=
    raises ArgumentError if the specified position exceeds the limit
    sets the buffer's position to a valid value
    raises ArgumentError if the specified position is less than zero
  #capacity
    has the requested capacity
  #mark
    returns self
  #reset
    raises NIO::ByteBuffer::MarkUnsetError unless mark has been set
    returns to a previously marked position
  #full?
