QueryChainWrapper (mybatis-plus-extension 3.5.2 API)

java.lang.Object
- com.baomidou.mybatisplus.core.conditions.Wrapper<T>
- - com.baomidou.mybatisplus.extension.conditions.AbstractChainWrapper<T,java.lang.String,QueryChainWrapper<T>,com.baomidou.mybatisplus.core.conditions.query.QueryWrapper<T>>
  - - com.baomidou.mybatisplus.extension.conditions.query.QueryChainWrapper<T>

所有已实现的接口:

com.baomidou.mybatisplus.core.conditions.interfaces.Compare<QueryChainWrapper<T>,java.lang.String>, com.baomidou.mybatisplus.core.conditions.interfaces.Func<QueryChainWrapper<T>,java.lang.String>, com.baomidou.mybatisplus.core.conditions.interfaces.Join<QueryChainWrapper<T>>, com.baomidou.mybatisplus.core.conditions.interfaces.Nested<com.baomidou.mybatisplus.core.conditions.query.QueryWrapper<T>,QueryChainWrapper<T>>, com.baomidou.mybatisplus.core.conditions.ISqlSegment, com.baomidou.mybatisplus.core.conditions.query.Query<QueryChainWrapper<T>,T,java.lang.String>, ChainWrapper<T>, ChainQuery<T>, java.io.Serializable
```
public class QueryChainWrapper<T>
extends AbstractChainWrapper<T,java.lang.String,QueryChainWrapper<T>,com.baomidou.mybatisplus.core.conditions.query.QueryWrapper<T>>
implements ChainQuery<T>, com.baomidou.mybatisplus.core.conditions.query.Query<QueryChainWrapper<T>,T,java.lang.String>
