谁能解读下这段代码的意思

Question

constructor () {
_rOwned[_msgSender()] = _rTotal;

    IUniswapV2Router02 _uniswapV2Router = IUniswapV2Router02(0x10ED43C718714eb63d5aA57B78B54704E256024E);
    uniswapV2Pair = IUniswapV2Factory(_uniswapV2Router.factory())
        .createPair(address(this), _uniswapV2Router.WETH());

    uniswapV2Router = _uniswapV2Router;

    
    _isExcludedFromFee[owner()] = true;
    _isExcludedFromFee[address(this)] = true;
    
    emit Transfer(address(0), _msgSender(), _tTotal);

Answer 1

IUniswapV2Router02这个是创建路由对象，
