Creates a new, read-only byte buffer that shares this buffer's
content.
<p> The content of the new buffer will be that of this buffer. Changes
to this buffer's content will be visible in the new buffer; the new
buffer itself, however, will be read-only and will not allow the shared
content to be modified. The two buffers' position, limit, and mark
values will be independent.
<p> The new buffer's capacity, limit, position, and mark values will be
identical to those of this buffer.
<p> If this buffer is itself read-only then this method behaves in
exactly the same way as the {@link #duplicate duplicate} method. </p>
