Buffer.length介绍

[英]The backing ByteBuffer is initially set along with initial position and length. This method returns the initial length if there was no operation on the backing ByteBuffer that would change the position (such as get or put). If the backing ByteBuffer position has been changed by reading or writing to the buffer, this method returns the change in position, i.e. difference between current position and initial position.
[中]缓冲垫的背衬最初与初始位置和长度一起设置。如果在backing ByteBuffer上没有任何操作会改变位置（如get或put），则此方法返回初始长度。如果通过读取或写入缓冲区更改了backing ByteBuffer位置，则此方法返回位置更改，即当前位置和初始位置之间的差值。

  // where +7 and the 8's are for getting to double word alignment
  return (((unencryptedInput.length() + 19) / 8) * 8);
