      • ensureWritableBytes

        public void ensureWritableBytes​(int minWritableBytes)
        从接口复制的说明: ChannelBuffer
        Makes sure the number of the writable bytes is equal to or greater than the specified value. If there is enough writable bytes in this buffer, this method returns with no side effect. Otherwise:
        • a non-dynamic buffer will throw an .
        • a dynamic buffer will expand its capacity so that the number of the writable bytes becomes equal to or greater than the specified value. The expansion involves the reallocation of the internal buffer and consequently memory copy.
