Modifier and Type	Interface and Description
`static interface`	`TransactionCoordinator.TransactionDriver` Provides the means for "local transactions" (as transaction drivers) to control the underlying "physical transaction" currently associated with the TransactionCoordinator.

`default void`	`invalidate()`
`boolean`	`isActive()` Is this transaction still active? Answers on a best effort basis.
`boolean`	`isJoined()` Determine if there is an active transaction that this coordinator is already joined to.
`default boolean`	`isTransactionActive()`
`default boolean`	`isTransactionActive(boolean isMarkedRollbackConsideredActive)`
`void`	`pulse()` Used by owner of the JdbcSession as a means to indicate that implicit joining should be done if needed.

- Method Detail
  - getTransactionCoordinatorBuilder
```
TransactionCoordinatorBuilder getTransactionCoordinatorBuilder()
```
    Access to the builder that generated this coordinator
  - getTransactionDriverControl
```
TransactionCoordinator.TransactionDriver getTransactionDriverControl()
```
    Get the delegate used by the local transaction driver to control the underlying transaction
    
    Returns:
    
    The control delegate.
  - getLocalSynchronizations
```
SynchronizationRegistry getLocalSynchronizations()
```
    Get access to the local registry of Synchronization instances
    
    Returns:
    
    The local Synchronization registry
  - getJpaCompliance
```
JpaCompliance getJpaCompliance()
```
  - explicitJoin
```
void explicitJoin()
```
    Indicates an explicit request to join a transaction. This is mainly intended to handle the JPA requirement around EntityManager.joinTransaction(), and generally speaking only has an impact in JTA environments
  - isJoined
```
boolean isJoined()
```
    Determine if there is an active transaction that this coordinator is already joined to.
    
    Returns:
    
    true if there is an active transaction this coordinator is already joined to; false otherwise.
  - pulse
```
void pulse()
```
    Used by owner of the JdbcSession as a means to indicate that implicit joining should be done if needed.
  - isActive
```
boolean isActive()
```
    Is this transaction still active?
    Answers on a best effort basis. For example, in the case of JDBC based transactions we cannot know that a transaction is active when it is initiated directly through the JDBC Connection, only when it is initiated from here.
    
    Returns:
    
    true if the transaction is still active; false otherwise.
    
    Throws:
    
    HibernateException - Indicates a problem checking the transaction status.
  - createIsolationDelegate
```
IsolationDelegate createIsolationDelegate()
```
    Retrieve an isolation delegate appropriate for this transaction strategy.
    
    Returns:
    
    An isolation delegate.
  - addObserver
```
void addObserver(TransactionObserver observer)
```
    Adds an observer to the coordinator.
    observers are not to be cleared on transaction completion.
    
    Parameters:
    
    observer - The observer to add.
  - removeObserver
```
void removeObserver(TransactionObserver observer)
```
    Removed an observer from the coordinator.
    
    Parameters:
    
    observer - The observer to remove.
  - setTimeOut
```
void setTimeOut(int seconds)
```
  - getTimeOut
```
int getTimeOut()
```
  - isTransactionActive
```
default boolean isTransactionActive()
```
  - isTransactionActive
```
default boolean isTransactionActive(boolean isMarkedRollbackConsideredActive)
```
  - invalidate
```
default void invalidate()
```
