    Returns the maximum number of NIO ByteBuffers that consist this buffer. Note that ByteBuf.nioBuffers() or ByteBuf.nioBuffers(int, int) might return a less number of ByteBuffers.

    返回:
    -1 if this buffer has no underlying ByteBuffer. the number of the underlying ByteBuffers if this buffer has at least one underlying ByteBuffer. Note that this method does not return 0 to avoid confusion.

    Exposes this buffer's bytes as an NIO ByteBuffer's for the specified index and length The returned buffer either share or contains the copied content of this buffer, while changing the position and limit of the returned NIO buffer does not affect the indexes and marks of this buffer. This method does not modify readerIndex or writerIndex of this buffer. Please note that the returned NIO buffer will not see the changes of this buffer if this buffer is a dynamic buffer and it adjusted its capacity.
