SynchronizationCallbackTarget (hibernate-jdk11 5.4.12.Final API)

所有已知实现类:

JtaTransactionCoordinatorImpl
```
public interface SynchronizationCallbackTarget
```
Defines "inflow" for JTA transactions from the perspective of Hibernate's registered JTA Synchronization back into the TransactionCoordinator by means of the SynchronizationCallbackCoordinator.
That's a mouthful :) The way it works is like this...
- Hibernate will register a JTA Synchronization implementation (RegisteredSynchronization) which allows it to listen for completion of the JTA transaction.
- That RegisteredSynchronization is given a SynchronizationCallbackCoordinator which it uses to route the transaction completion calls back into Hibernate. The SynchronizationCallbackCoordinator contract applies various behaviors around this process. See the impls for details.
- The SynchronizationCallbackCoordinator is handed a SynchronizationCallbackTarget which is the specific means for it to "route the transaction completion calls back into Hibernate". The SynchronizationCallbackTarget is most often the TransactionCoordinator impl or a direct delegate of the TransactionCoordinator impl. In that sense, SynchronizationCallbackTarget is the contract between the SynchronizationCallbackCoordinator and the TransactionCoordinator.

方法概要

所有方法实例方法抽象方法
修饰符和类型	方法	说明
`void`	`afterCompletion(boolean successful, boolean delayed)`	Callback of after-completion.
`void`	`beforeCompletion()`	Callback of before-completion.
`boolean`	`isActive()`	Is the callback target still active?

- 方法详细资料
  - isActive
```
boolean isActive()
```
    Is the callback target still active? Generally this is checked by the caller prior to calling beforeCompletion() or afterCompletion(boolean, boolean)
    
    返回:
    
    true indicates the target is active; false indicates it is not.
  - beforeCompletion
```
void beforeCompletion()
```
    Callback of before-completion.

    Synchronization.beforeCompletion()
  - afterCompletion
```
void afterCompletion(boolean successful,
                     boolean delayed)
```
    Callback of after-completion.
    
    参数:
    
    successful - Was the transaction successful?
