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

io.netty.buffer.ByteBuf.slice()
Returns a slice of this buffer's readable bytes. Modifying the content of the returned buffer or this buffer affects each other's content while they maintain separate indexes and marks. This method is identical to {@code buf.slice(buf.readerIndex(), buf.readableBytes())}. This method does not modify {@code readerIndex} or {@code writerIndex} ofthis buffer.
