Transaction

All Superinterfaces:

java.lang.AutoCloseable, Graph
```
public interface Transaction
extends Graph, java.lang.AutoCloseable
```
交予客户用的事务API

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method and Description
`default void`	`close()` 等效于`txClose()`
`void`	`txClose()` 提交事务提交前需要执行`txSuccess()`或`txFailure()`否则默认回滚
`void`	`txFailure()` 标记事务失败标记完毕后即可调用`txClose()`或`close()`回滚
`long`	`txId()` 事务Id
`boolean`	`txIsFailure()` 事务是否被标记为失败
`boolean`	`txIsOpen()` 事务是否仍然存活
`boolean`	`txIsSuccess()` 事务是否被标记为成功
`void`	`txSuccess()` 标记事务成功标记完毕后即可调用`txClose()`或`close()`提交
