Examples of io.netty.buffer.ByteBuf.copy()

io.netty.buffer.ByteBuf.copy()
Returns a copy of this buffer's readable bytes. Modifying the content of the returned buffer or this buffer does not affect each other at all. This method is identical to {@code buf.copy(buf.readerIndex(), buf.readableBytes())}. This method does not modify {@code readerIndex} or {@code writerIndex} ofthis buffer.
