 Public 成员函数 继承自 bplus_tree::LogEntryHandler | |
| LogEntryHandler (LogOperation operation, Frame *frame=nullptr) | |
| Frame * | frame () |
| 返回日志对应的frame 更多... | |
| const Frame * | frame () const |
| PageNum | page_num () const |
| void | set_page_num (PageNum page_num) |
| LogOperation | operation_type () const |
| 日志操作类型 | |
| RC | serialize (common::Serializer &buffer) const |
| 序列化日志 | |
| RC | serialize_header (common::Serializer &buffer) const |
| 序列化日志头 | |
| virtual RC | serialize_body (common::Serializer &buffer) const =0 |
| 序列化日志内容。所有子类应该实现这个函数 更多... | |
| virtual RC | rollback (BplusTreeMiniTransaction &mtr, BplusTreeHandler &tree_handler)=0 |
| 回滚 更多... | |
| virtual RC | redo (BplusTreeMiniTransaction &mtr, BplusTreeHandler &tree_handler)=0 |

额外继承的成员函数 | |
| 静态 Public 成员函数 继承自 bplus_tree::LogEntryHandler | |
| static RC | from_buffer (function< RC(PageNum, Frame *&)> frame_getter, common::Deserializer &buffer, unique_ptr< LogEntryHandler > &handler) |
| 从buffer中反序列化出一个LogEntryHandler 更多... | |
| static RC | from_buffer (DiskBufferPool &buffer_pool, common::Deserializer &buffer, unique_ptr< LogEntryHandler > &handler) |
| static RC | from_buffer (common::Deserializer &deserializer, unique_ptr< LogEntryHandler > &handler) |
| Protected 属性 继承自 bplus_tree::LogEntryHandler | |
| LogOperation | operation_type_ |
| Frame * | frame_ = nullptr |
| PageNum | page_num_ = BP_INVALID_PAGE_NUM |
| page num本来存放在frame中。但是只有在运行时才能拿到frame，为了强制适配 解析文件buffer时不存在运行时的情况，直接记录page num | |
