com.baomidou.mybatisplus.core.conditions.Wrapper<T>

com.baomidou.mybatisplus.core.conditions.AbstractWrapper<T,R,Children>

icu.mhb.mybatisplus.plugln.core.support.SupportJoinWrapper<T,R,Children>

所有已实现的接口:

com.baomidou.mybatisplus.core.conditions.interfaces.Compare<Children,R>, com.baomidou.mybatisplus.core.conditions.interfaces.Func<Children,R>, com.baomidou.mybatisplus.core.conditions.interfaces.Join<Children>, com.baomidou.mybatisplus.core.conditions.interfaces.Nested<Children,Children>, com.baomidou.mybatisplus.core.conditions.ISqlSegment, IfCompareFun<Children,R>, Serializable

直接已知子类:

SupportJoinChainQueryWrapper, SupportJoinLambdaWrapper

public abstract class SupportJoinWrapper<T,R,Children extends SupportJoinWrapper<T,R,Children>>
extends com.baomidou.mybatisplus.core.conditions.AbstractWrapper<T,R,Children>
implements IfCompareFun<Children,R>
