类 DbChain

java.lang.Object

com.mybatisflex.core.query.BaseQueryWrapper<QueryWrapper>

com.mybatisflex.core.query.QueryWrapper

com.mybatisflex.core.query.QueryWrapperAdapter<DbChain>

com.mybatisflex.core.row.DbChain

所有已实现的接口:

CloneSupport<QueryWrapper>, PropertySetter<DbChain>, Serializable, Cloneable

public class DbChain
extends QueryWrapperAdapter<DbChain>
implements PropertySetter<DbChain>

链式构建 QueryWrapper 并执行 Db 方法。
