public ByteBuf copy(int index, int length)

Overrides io.netty.buffer.ReadOnlyByteBufferBuf.copy.

Doc from io.netty.buffer.ByteBuf.copy.

Returns a copy of this buffer's sub-region. Modifying the content of the returned buffer or this buffer does not affect each other at all. This method does not modify readerIndex or writerIndex of this buffer.
