方法名：asReadOnlyBuffer

ByteBuffer.asReadOnlyBuffer介绍

[英]Returns a read-only buffer that shares its content with this buffer.

The returned buffer is guaranteed to be a new instance, even if this buffer is read-only itself. The new buffer's position, limit, capacity and mark are the same as this buffer.

The new buffer shares its content with this buffer, which means this buffer's change of content will be visible to the new buffer. The two buffer's position, limit and mark are independent.
[中]返回与此缓冲区共享其内容的只读缓冲区。
返回的缓冲区保证是一个新实例，即使该缓冲区本身是只读的。新缓冲区的位置、限制、容量和标记与此缓冲区相同。
新缓冲区与此缓冲区共享其内容，这意味着此缓冲区的内容更改将对新缓冲区可见。两个缓冲器的位置、极限和标记是独立的。
