该代码在BEP20代币书写中意味着什么
我试图了解BEP20代码的这一行是什么意思，它是以坚固的
constructor () {
_rOwned[owner()] = _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), owner(), _tTotal);
I'm trying to understand what this lines of BEP20 code mean, it is written in solidity
constructor () {
_rOwned[owner()] = _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), owner(), _tTotal);

在第一行中，他将UnisWapv2Router实例化，将地址路由器指向Pancakeswap。这是因为，他想用他的令牌和BNB创建一个流动性池，实际上，在他称之为
createpair（）的实施操作之后，他可以在智能合约和地址weth（）之间创建这对这对（） 。重要： weth（）是提供者部署智能合约的链条本机包装的硬币地址的功能。例如：如果我在以太坊区块链上创建一个对uniswap路由器进行实现的对，则weth（）将返回有关
weth（包装以太）地址的地址。相反，如果我将其地址呈现在二元智能链中的Uniswap路由器（因此在这种情况下是指pancakeswap），则WETH（）的值将为wbnb地址。经过这一行之后，我假设他不包括交易支付费用
lands（）地址（谁首次部署了智能合约）和智能合约本身。Finally he emitted a Transfer event passing :
address(0)(0x0000000000000000000000000000000000000000),owner()andtotal supply.有关对文档的更多信息。
In the first lines, he instanciate UniswapV2Router pointing the address router to PancakeSwap. This because, he want to create a liquidity pool with his TOKEN and BNB, indeed after this instanciating operation he call
createPair()that allows him to create this pair between his smart contract and the address WETH().IMPORTANT: WETH() is a function that provider the chain native wrapped coin address where smart contract was deployed. For example: If I create a pair instanciating Uniswap router on Ethereum blockchain then WETH() will return address about
WETH(Wrapping Ether) address present into Etheruem. On the contrary if I instanciate Uniswap Router with its address present into binance smart chain (and so I refers to Pancakeswap in this case), the value of WETH() will beWBNBaddress.After this lines of code, I assume that he excluded from paying a fee for only transactions the
owner()address (who deployed the smart contract for the first time) and smart contract itself.Finally he emitted a Transfer event passing :
address(0)(0x0000000000000000000000000000000000000000),owner()andtotal supply.More information about pair on documentation.
