类 EqualsComparatorWithErrorCode<T>

java.lang.Object

cn.gongler.util.EqualsComparatorWithErrorCode<T>

public class EqualsComparatorWithErrorCode<T>
extends Object

比较用户名、密码、IP等信息，并返回错误码或信息。如果不需要返回错误码，比直接调用Comparater，可以指出差异项，并生成代码编号。

 例：转发服务器验证用户登录并返回错误码的代码：
 Tuple2<Integer, Object> result = EqualsComparatorWithErrorCode.of(LoginResponsePack.LOGIN_SUCESS)
 .compare(loginPack.username(), xmlUser.username(), LoginResponsePack.LOGIN_USERNAME_MISTAKE)
 .compare(loginPack.password(), xmlUser.password(), LoginResponsePack.LOGIN_PASSWORD_MISTAKE)
 .compare(loginPack, xmlUser, (p, u) -> u.ipcheck(p.remoteAddr().getAddress()), LoginResponsePack.LOGIN_IP_MISTAKE)
 .result();
 int errCode = result.first();
 Object incorrectedVal = result.second();
 LoginResponsePack ackPack = new LoginResponsePack(loginPack, errCode, incorrectedVal);
