```
public interface TransactionCoordinator
```
Models the coordination of all transaction related flows.

Nested Class Summary

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

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`void`	`addObserver(TransactionObserver observer)`	Adds an observer to the coordinator.
`IsolationDelegate`	`createIsolationDelegate()`	Retrieve an isolation delegate appropriate for this transaction strategy.
`void`	`explicitJoin()`	Indicates an explicit request to join a transaction.
`JpaCompliance`	`getJpaCompliance()`
`SynchronizationRegistry`	`getLocalSynchronizations()`	Get access to the local registry of Synchronization instances
`int`	`getTimeOut()`
`TransactionCoordinatorBuilder`	`getTransactionCoordinatorBuilder()`	Access to the builder that generated this coordinator
`TransactionCoordinator.TransactionDriver`	`getTransactionDriverControl()`	Get the delegate used by the local transaction driver to control the underlying transaction
`default void`	`invalidate()`
`boolean`	`isActive()`	Is this transaction still active?
`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 "JDBC session" as a means to indicate that implicit joining should be done if needed.
`void`	`removeObserver(TransactionObserver observer)`	Remove an observer from the coordinator.
`void`	`setTimeOut(int seconds)`

- 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 "JDBC session" 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)
```
    Remove 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()
```
